This page features profiles of the demand response (DR) and time-variable pricing (TVP) offerings from utilities in western states, as well as from independent system operators (ISOs) such as MISO and CAISO (the Midcontinent and California ISOs). TVP options are offered by most utilities and can range from simple time-of-use (TOU) rates, in which prices vary at pre-set levels through the day (usually with peak, off-peak, and two "shoulder" periods), to truly "dynamic" rates such as real-time and day-ahead hourly pricing.

Alaska

Chugach Electric Association has an interruptible rate (Schedule 27) available to secondary voltage customers with peak demands over 100 kW. In exchange for their willingness to be interrupted, customers on this tariff are not assessed a demand charge.

Arizona

Both APS and SRP offer time-of-use rates for commercial customers. These rates provide utility bill savings for customers who can shift electricity use to off-peak hours, particularly during the summer. APS also offers the time-of-week price plan demand response program to its commercial and industrial customers. The program is offered through CPower and allows customers to earn revenue for being available to curtail load on short notice when the grid is stressed. APS provides 60 minutes notice prior to an interruption. The program runs from June 1–September 30, and events can be called anytime between 4 and 9 p.m. Events last anywhere from 1–5 hours on a maximum of three consecutive days. Capacity and energy payments of $40 per kW and $0.09 per kWh, respectively, are paid to customers for reducing their energy consumption.

Tuscon Electric Power's (TEP) Smart Demand Response (SmartDR) Program offers large commercial and industrial customers the opportunity to reduce energy costs by reducing energy use at times of high demand. The program provides quarterly bill credits to customers who agree to be notified by TEP during high demand events and asked to reduce their energy use according to an "energy reduction plan," which they design in collaboration with TEP.

TEP also offers the Interruptible Service Program to commercial customers for agreeing to electric service interruptions during times of high demand. TEP provides 30-minute notices prior to an interruption. Bill credits are issued monthly based on the kilowatt (kW) capacity that customers agree to curtail and TEP's "market value capacity price" (MVCP). The program is only available to customers with demand that exceeds 3,000 kW, and participating customers must agree to curtail at least 1,000 kW at a single service point. Interested customers may subscribe between April 1–15 of each program year.

California

PG&ESDG&E, and SCE, as well as the California Independent System Operator (CAISO), offer a number of statewide programs:

  • The automated demand response (auto-DR) offerings of PG&ESCE, and SDG&E provide free technical assistance and generous incentives to customers for installing automated DR equipment. Participation is open to customers enrolled in a qualifying DR or time-varying pricing option (PG&E’s Peak Day Pricing or SCE's and SDG&E's Critical Peak Pricing program). Auto-DR uses communication and control technology to automatically implement the customer's chosen pre-programmed load reductions, providing a fast and reliable way to respond to peak events, while still leaving the customer in complete control. The incentive is $200/kW (up to 75% of total equipment and installation costs) for measured and verifiable automated load reductions. Eligible equipment includes energy management systems and software, wired and wireless controls for lighting, HVAC, thermostats, motors, pumps and other equipment capable of receiving curtailment signals. SCE also offers the Auto-DR Express program to customers with a peak demand between 50 and 499 kW. Incentives under this program are either $300/kW or 100% of total actual eligible project costs, whichever is less.
     
  • The Base Interruptible Program (BIP) offered by PG&ESCE, and SDG&E pays participants to reduce electric load to (or below) a level pre-selected by the customer (called the firm service level or FSL) that is below its historic average maximum demand. Customers receive a monthly incentive payment or credit based on the size of the curtailable portion of their load, in return for committing to reduce to the FSL when called upon by the utility with 15–30 minutes' notice, depending on the utility. The incentives are up to $11.50 per committed kW per month, even if no events are called. There is a minimum curtailment commitment of 100 kW, or 15% of the monthly average peak demand (whichever is larger). Customers are also required to take service under a time-of-use (TOU) or real-time pricing (RTP) rate to be eligible for this program. Requests for curtailments (which can last up to six hours) cannot exceed one per day, 10 per month, or 180 hours per year. Penalties apply for customers that fail to reduce load as requested; the amount depends on the utility and the incentive option. All three utilities have contracted with numerous third-party aggregators (also known as curtailment service providers, CSPs) who recruit customers to participate in BIP and manage their participation process. By serving as an intermediary, the aggregators can handle many of the details on customers' behalves and help them develop load reduction strategies. The aggregators may also offer innovative program features – for example, by assuming the risk of non-compliance penalties or by allowing customers to participate who might otherwise be too small to enroll directly in the utility's program. BIP participants are also eligible for simultaneously participating in other load management opportunities offered by the utilities (e.g., time-varying pricing or PG&E/SCE’s Demand Bidding Program), which allows customers to take advantage of rate credits, reduced energy charges, and incentives associated with both programs, with some restrictions.
     
  • Under the Capacity Bidding Program (CBP), PG&ESCE, and SDG&E participants receive a monthly incentive for pledging to reduce their energy use by a pre-determined amount in the event a CBP event is called by the utility. Events can occur weekdays year-round or from May through October, depending on the utility. The time periods for the events vary across utilities and program options (e.g. 11 a.m.–7 p.m., 1–7 p.m. or 1–9 p.m.). The program offers either a day-ahead or day-of notification option; participants opting for the latter receive higher incentives. Customers receive the monthly payment (varies by utility, time of year, and notification option) whether or not an event is called. Failure to reduce the pledged amount during an event will result in reduced incentives and, for those not meeting at least 50% of the pledge, possible penalties. Customers typically enroll in CBP through a third-party aggregator/curtailment service provider (CSP), who manages their participation and relays their monthly reduction pledge, which can vary. PG&E CBP participants may also be eligible to concurrently participate in additional PG&E demand response programs.
     
  • The California Independent System Operator (CAISO) offers its Proxy Demand Response and Reliability Demand Response programs for commercial customers who can curtail at least 500 kW. Participating customers can bid directly into the wholesale day ahead or real time markets (Reliability Demand Response program) or through a CSP (Proxy Demand Response program). Participants must be able to fully curtail their committed load within 40 minutes of an event being called and maintain that reduction for at least four hours. CAISO can call up to 15 events or 48 total hours of curtailment per six-month term. The summer term runs from June through September and winter term from October through May.

The following demand response and time-of-use programs are not common to all California utilities:

  • PG&E offers time-of-use rates for commercial customers in California. These rates provide utility bill savings for customers who can shift electricity use to off-peak hours, particularly during the summer (June through September). On-peak hours are every day from 4 to 9 p.m.
     
  • SDG&E also offers time-of-use rates for its commercial customers. Similar to PG&E's, these rates offer savings for load shifting to off-peak hours, particularly during the summer. On-peak hours are defined as 4–9 p.m.
     
  • SCE also provides time-of-use rates. On-peak hours are defined as 4–9 p.m. As with PG&E and SDG&E, price disparities are most pronounced during the summer (June 1 to September 30), including weekends and holidays.
     
  • Critical Peak Pricing (CPP) from SCE and SDG&E is a time-of-use rate structure that offers lower electricity rates year-round in return for setting a higher rate on specific summer afternoons. The rate is three to five times higher than the regular rate on up to fifteen (SCE) or 18 (SDG&E) "critical peak" afternoons during the summer with customers notified of CPP days on a day-ahead basis. Summer months for SCE occur from June through September and for SDG&E from May through October. CPP events are called between 4 and 9 p.m. Customers are notified via email or text by 3 p.m. the day before an event is called. CPP is the default rate for small, medium, and large commercial and industrial customers as well as large agricultural and pumping customers of SCE. For new program entrants, a bill protection option is available that prevents participants from paying more than they would have under their previous rate during the first year of CPP participation. Participants may also opt for technical assistance to help them better take advantage of the program. SDG&E customers participating in the Day-Ahead option of the Capacity Bidding Program are not eligible for CPP.
     
  • PG&E's Peak Day Pricing (PDP), very similar to SCE's and SDG&E's Critical Peak Pricing (see above), is the default rate for PG&E's large commercial, industrial and agricultural customers. PDP imposes substantial additional charges during critical peak times (4–9 p.m. on 9 to 15 "Peak Event Days" per year, with some alternative durations available). Participants shield their exposure to high prices during PDP events by shedding load during the peak price hours. Customers on E-19 and E-20 rate schedules (demand of 500 kW–999 kW and 1000+ kW respectively) have the option to mitigate bill fluctuation by allotting a portion of their load to a "capacity reservation." For new program entrants, a bill protection option is available that prevents participants from paying more than they would have under their previous rate during the first year of CPP participation.
     
  • Commercial and industrial customers can also enroll in SCE’s Real-Time-Pricing (RTP) Program, which is designed to incentivize participants to reduce load or shift their demand to lower-priced hours. Pricing under this program is based on the time of day, season, and prior-day temperature, providing customers with multiple pricing options to choose from. The summer season is defined as June through September and winter season as October through May. Customers can receive day-ahead notifications of hourly prices via SCE’s DR alerts app. Customers enrolled in the RTP program can also enroll in other SCE demand response programs.
     
  • PG&E and SCE offer the Optional Binding Mandatory Curtailment Program, which provides customers with exemptions from rotating power outages if they can reduce their circuit load during Stage 3 emergencies. Participants must reduce their power consumption by 15% below their established baseline load for the duration of every rotating outage event. 
     
  • SCE’s Summer Discount Plan and SDG&E's Summer Saver program are summer air conditioner cycling programs for commercial customers. These "direct load control" programs provide a credit on participants' summer season electric bills in return for allowing the utility to cycle air conditioners when needed during the months of June through October (SCE) and April to October (SDG&E). Customers can choose among several options regarding the frequency and duration of curtailments, each with corresponding remuneration levels. Curtailment events may occur any day of the week.
     
  • SDG&E offers the Smart Thermostat Program, which allows the utility to remotely adjust participating customers’ thermostats when an AC Saver Thermostat activation or Critical Peak Pricing day/event is called The rate and/or program a customer is enrolled in determines the times of day and year that events may be called.  Most commonly, events are between 12 and 9 P.M., April through October.  Customers receive $50 for every thermostat they register (limit of four thermostats per customer). Thermostats are adjusted for no longer than four hours per event and customers can opt out of the temperature adjustment if they do not want to participate that day.
     
  • SCE offers the Scheduled Load Reduction Program (SLRP) to qualified bundled-service customers whose average monthly demand is 100 kW or more. The program provides a $0.10 per kWh on-bill credit for reducing load by at least 15% on prescheduled days and times on weekdays from June 1 through September 30. Customers can choose different four-hour periods: 8 a.m. to 12 p.m.; 12 to 4 p.m.; and 4 to 8 p.m.
     
  • SCE offers the Agricultural and Pumping Interruptible Program (AP-I), which helps customers save on energy costs in exchange for allowing SCE to temporarily interrupt electric service during times of peak demand. Eligible customers must have a demand of 37 kW or greater, or at least 50 horsepower of connected load. Customers allow SCE to install remote-controlled switches on their agricultural and pumping equipment that can automatically shut off the equipment when called upon by SCE. Service interruptions may occur at any time of the year, seven days a week. Events are limited to one per day, no longer than six hours per event, and may occur up to 25 times per year, or 150 hours total. Customers may request courtesy notifications via email, phone, or text message.
     
  • SDG&E offers its commercial/industrial customers the Electric Vehicle-High Power rate, which aims to eliminate unpredictable demand charges by offering lower rates and bill stability through fixed monthly subscription charges. This rate uses reduced time-of-use energy charges that are incurred based on the time of day the customer charges their electric vehicle(s). Energy charges are separated out into peak, off-peak, and "super off-peak" prices.
     
  • PG&E offers two electric vehicle rate plans (BEV1 and BEV2) for business customers with on-site EV charging. Both plans combine a customizable monthly subscription charge with a time-of-use rate. When charging during off-peak (9 p.m. – 9 a.m. and 2– 4 p.m.) and "super off-peak" (9 a.m.–2 p.m.) hours customers are offered a lower rate than when charging during peak times (4–9 p.m.).
     
  • SCE offers time-of-use Electric Vehicle Rates to Charge Ready program participants. Three rates are offered depending on customer charging demands. Customers pay lower rates when charging during off-peak and "super off-peak" hours. Summer (June 1-September 30) off-peak hours are from 9 to 4 p.m. (19 hours) and winter (October 1 – May 31) off-peak hours are from 9 p.m. – 8 a.m. with super off-peak hours from 8 a.m. –4 p.m.
     
  • Glendale Water and Power offers time-of-use pricing for its smallmedium, and large business customers. These rates provide utility bill savings for customers who can shift electricity use to off-peak hours, particularly during the summer. On-peak hours are defined as 2–8 p.m., Monday through Friday, from July through October and 12 to 9 P.M., Monday-Friday, from November through June.
     
  • Sacramento Municipal Utility District (SMUD) offers the PowerDirect Automated Demand Response program. Participating customers have automated controls installed on their lighting and/or HVAC systems that will automatically curtail system usage during peak periods. The program incentive is $5/kW per month and requires a one-year commitment. There are also generous incentives to cover the cost of installing the automated controls technology. Customers must be able to reduce usage for at least two consecutive hours during peak periods, and achieve at least 50% of their load reduction goal each event hour on eight of the called "conservation days," which take place between June 1–September 30. Peak periods occur from 2 to 6 p.m. on weekdays. Curtailment events last between 1–4 hours. Customers will receive notification at least 30 minutes prior to a curtailment event, and often the day before.
     
  • SMUD also offers time-of-use rates to commercial and industrial customers that incentivize them to shift their demand away from peak periods. Peak periods take place during non-holiday weekdays from 4 to 9 p.m. during both summer (June through September) and winter (October through May).
     
  • The Los Angeles Department of Water and Power (LADWP) offers financial incentives for participating in their demand response (DR) offering. Customers are eligible to receive two different incentives, one for "capacity," another for actual event participation. The event incentive is $0.25/kWh. The capacity incentive is based on committed kW curtailment capacity, with a minimum 50% performance during the DR events required. If an event is not called during a given month, capacity incentives are still granted. Customers who select the day-ahead notification option will receive an $8/kW monthly payment, which escalates to $12/kW in the two-hour advance notification option. Participants must be able to curtail at least 100 kW. Program details include a maximum of 12 events per season, maximum of one event per day, and maximum of four hours per event. The program season is from June 15–October 15, and operates between 1–5 p.m.
     
  • LADWP offers the Summer Shift Time-of-Use program for commercial customers in California. These rates provide utility bill savings for customers who can shift electricity use to off-peak hours, particularly during the summer (June through September). High-peak hours are defined as Monday–Friday, 1–5 p.m. and "low-peak" periods are Monday to Friday, 10 a.m. to 1 p.m. and 5 to 8 p.m.

Colorado

Xcel Energy's Interruptible Service Option Credit (ISOC) provides opportunities for significant electric bill savings to customers who have a contract interruptible load (the median of maximum demands from 12–8 p.m. weekdays, excluding holidays, from June 1 to September 30 of the previous year) from which they can cut at least 300 kW for a minimum of four hours when called. Remuneration in the form of a monthly credit is based on the maximum annual hours of interruption and the advance notice needed, so it ranges widely. Most events occur during summer weekdays, but can be called at any time. Participants can sign up for the year any time before May 31.

Through the Peak Partner Rewards program, Xcel customers with as little as 25 kW in reduction capability can earn $2/kW per month for their committed cuts, as well as $0.70/kWh for actual event participation. Events, of which there can be up to 15 per summer (June 1–September 30), last between one and four hours and take place between 2–6 p.m. on weekdays. Curtailment events can be called outside of these times and months; however, customers are not obligated to participate outside of their committed period. Participants must respond with as little as one hour's notice. No more than one curtailment event can be called per day. The initial contract term is 24 months and can be extended on an annual basis.

Through the Peak Day Partners (PDP) program, Xcel customers who can reduce demand by at least 500 kW can receive credit for reducing their load during peak event times. Events usually occur on weekday afternoons in the summer (June 1–September 30). The day before events, participants are contacted to determine willingness to reducing their electricity load and to establish a purchase price for their energy reduction. They can then accept or decline Xcel's offer, or provide a counter offer. Once the offer is accepted, participants are committed to a minimum load reduction for each hour of the buyback period relative to a "baseline load profile" determined from the five highest energy consumption days within the last ten non-holiday weekdays. Remuneration is provided in the form of a bill credit or separate payment.

Xcel also offers a Critical Peak Pricing option, in which customers able to cut their loads for up to four hours between 12–8 p.m. on up to 15 non-holiday weekdays per year are assessed a lower demand charge that can save them 5%–10% of their total electricity bill. During events, though, electricity prices are many times higher than usual. Customers are notified by the utility at least 22 hours prior to a critical peak event. The contract term to participate in this program is a minimum of 12 months.

The EV Critical Peak Pricing Program allows Xcel commercial and industrial customers to save money on energy costs by shifting electrical vehicle charging away from critical peak events to off-peak hours. Critical peak pricing events can be called from 12–8 p.m. on non-holiday weekdays and last no more than four hours. These events can occur up to 15 times per year, but not more than once per day. Customers will receive notification via email, text, or voice message no later than 4 p.m. the previous day. Customers cannot participate in the EV Critical Peak Pricing Program and also receive the Interruptible Service Option Credit (see above).

Colorado Springs Utilities offers its Peak Savings Program to customers willing to commit to curtailing at least 5% of their electric load for up to four hours on summer (May 1–September 30) weekdays between 11 a.m.–6 p.m. Participants receive event notice 8–24 hours in advance, and no more than 10 times per summer. In exchange, they receive an annual incentive of $50 per committed kW, as well as a facility walk-through to help them identify good curtailment opportunities.

CSU also offers a time-of-use rate to its commercial customers whose daily use averages less than 1,000 kWh/day in the last 12 billing periods, with savings for customers able to shift load away from peak times (11 a.m.–6 p.m., April to September and 4-10 p.m., October through March).

Fort Collins Utilities (FCU) provides a Load Management Tool to commercial and industrial customers with peaks over 50 kW that can help reduce electricity demand during the utility's peak hour of each month, also known as the coincident peak. These customers are assessed a coincident peak demand charge of roughly $15/kW in summer months and $12/kW during non-summer months. The Load Management Tool provides customers with the ability to track the demand of FCU's wholesale power supplier, Platte River Power Authority. Customers can sign up to receive an email during potential peak hours indicating when to shed load. It is impossible to predict when the peak hour of the month will occur, so FCU identifies about 10 potential peak hours per month.

Hawaii

Hawaiian Electric Company (HECO) offers small and large business customers several options under its Demand Response Business Solutions initiative.

HECO's Large Commercial and Industrial Direct Load Control (CIDLC) program, also known as EnergyScout™ for Business, provides customers with free installation of a device that can curtail customer-designated loads. Participating customers receive monthly bill credits based on the magnitude of the load they let HECO control, regardless of whether a DR event is called. In the unusual event that a DR event lasting more than one hour occurs, program participants receive an additional incentive. This program is currently fully subscribed and HECO is directing interested customers towards its Fast DR program (see below) instead.

HECO's Small Business Direct Load Control (SBDLC) program, also known as EnergyScout™ for Small Business, provides customers with free installations of a device that can temporarily turn off water heaters or cycle air conditioners for no longer than an hour. Participants receive a monthly credit of $5 for each participating water heater and each ton of air conditioning. Incentives are received regardless of whether an event is called. The program is currently fully subscribed; interested customers should check the link above for updates.

HECO's Fast Demand Response (DR) program is intended to stabilize the grid and prevent unplanned outages during times when demand exceeds generation capacity. Program participants agree to have controllers installed on non-essential equipment. However, they maintain complete control of their equipment and can opt out of participating in any event. Events occur between 7 a.m. and 9 p.m. on weekdays and last a maximum of one hour. Participants have 10 minutes to reduce the participating energy load once the event has been initiated. Customers can participate in 40 events per year at $5/kW each month or 80 events at $10/kW per month. There is a minimum load shed requirement of 50 kW, which amounts to $3,000 or $6,000 per year for 40- and 80-event participants, respectively.

HECO is offering new commercial EV rates through a five-year pilot program (2022-2027) that incentivizes charging during mid-day hours (when grid power from solar PV installations is plentiful). Three rates are offered through the pilot program, EV-J, EV-F, and EV-P. For more information on these rates visit HECOs Commercial Facility Pilot rates page.

Idaho

Idaho Power's FlexPeak Management program is a highly customizable demand response program that utilizes web-based software to provide real-time energy information to manage energy use and reduce peak load during the program period (June 15–August 15, 2–8 p.m., Mondays through Fridays). Commercial and industrial customers who are able to reduce a minimum of 20kW when an event is called are eligible. Participants receive financial incentives for agreeing to be "on call" to respond within two hours to demand reduction events. A fixed payment of $3.25/kW per week is paid even for weeks when events are not called. For weeks when an event is called, customers will receive the $3.25/kW payments based on the actual kW reduction achieved during the event. After three events are called in a season, additional incentives of $0.16/kWh are provided for actual energy reductions during events, which last from two to four hours each.

Idaho Power offers a direct load control option, the Irrigation Peak Rewards program to agricultural customers for allowing irrigation pumps to be remotely shut off during peak electricity usage. The program runs from June 15 to August 15 and offers participants $5 per kW of controlled load plus a small additional incentive for kWh actually reduced; if the number of events exceeds three, the kWh incentive for actual events goes up dramatically. Individual irrigation pumps have a load control device installed at the pump location. Load control events can occur any weekday or Saturday between 1 and 9 p.m. Customers are notified four hours before each event, if possible, by the company. A minimum of three load control events, each lasting no more than four hours, will occur each program season. The company, however, also offers an option to opt out of a specific load control event in exchange for a fee.

Rocky Mountain Power offers the Interruptible Power Service schedule to customers with loads of 1,000 kW or greater. Customers are remunerated based on the level of load curtailment they are able to commit to. Customers may commit to a guaranteed availability level of 60%, 70%, 80%, or 90% of their contract demand. A contract term of one year or longer is required.

Rocky Mountain Power's Irrigation Load Control program offers financial incentives to irrigators who agree to curtail electricity use during peak demand periods. Irrigators choose which sites to enroll in the program and which load control option best suits their needs. Rocky Mountain Power's third-party vendor, EnelX, then installs a device that allows customers to access an online portal to monitor usage and control their demand. Compensation is determined by multiplying the average load (kW) a customer can reliably shut off during program hours by the incentive rate, adjusted for event participation. The incentive rate is set by customer's average expected kW per pump. The program runs from June 1 through August 15. Events can be called only during weekdays from 2 to 9 p.m. Participants receive a 20% bonus if the listed pumps participate in every event that lasts until 9 p.m. The utility is limited to 20 events and 52 event-hours (and no more than 12 event-hours in any given week). Customers receive notification by 5 p.m. the day before an event.

Rocky Mountain Power offers its Time-of-Day rate for commercial and industrial customers of any size. Customers who can shift their usage to off-peak periods will see utility bill savings. On-peak periods are defined as 7 a.m. to 10 p.m. during winter (November–April) and 8 a.m. to 11 p.m. during summer (May–October), Monday through Friday, excluding holidays. Off-peak periods are all other times.

Bonneville Power Authority (BPA), a wholesale power supplier to utilities in the northwest, supports demand response by utilities and their customers in its footprint, but does not currently offer DR programs for end-use customers.

Kansas

Evergy (formerly Kansas City Power and Light) offers time-of-use plans where customers can shift their energy use away from on-peak hours (1–8 p.m. in the summer and 10 a.m.–8 p.m., Monday to Friday, in the winter).

Evergy also offers an Electric Vehicle Plan to EV owners. Customers can lower their vehicle charging costs substantially by shifting charging outside of peak hours (2-8 p.m.) and ideally into the program's "super off-peak" period of midnight to 6 a.m.

Minnesota

Xcel Energy offers the Electric Rate Savings program, which provides financial incentives for peak demand reduction at commercial and industrial facilities that can reduce load by 50 kW or more during peak periods, primarily in the summer (June–September). Customers can be called on to reduce anytime during the year, but the great majority of events occur in the summer. Participating customers receive a per-kW discount on controllable demand every month, but in exchange must commit to reducing their load to a pre-determined level for up to 150 hours per year. Customers can also add time-of-day service and save more on energy costs by shifting part of their load to off-peak hours (9 p.m.–9 a.m.).

In addition, Xcel offers the Peak Partner Rewards program, which provides bill credits to customers who agree to reduce their energy usage during times of peak demand. Customers enrolled in this program provide a minimum of 25 kW of interruptible load from June to September. Participants are given a one-hour notice before load curtailment events, which last anywhere from 1–4 hours. Events are most likely to occur during weekdays from 12 to 8 p.m. There is a maximum of 15 events per year.

Also available from Xcel is the Saver’s Switch for Business program, offering participants a monthly discount of $5 per ton of enrolled air conditioning in exchange for allowing the utility to cycle the air conditioning on and off for 15–20 minute intervals during periods of peak electric demand in the summer (June–September). The maximum amount of allowable control hours is 300 hours per year.

Customers can save on natural gas costs when they enroll in the Interruptible Gas Rate program. This program allows business customers to receive a one-hour notice from Xcel that they must go off the gas system and curtail their load completely during periods of peak gas demand, like cold winter mornings. Customers can reserve up to 15 days of gas supply for use during curtailment days in order to maintain operations of their facilities. A designated phone line connection to Xcel’s telemetering device is required. Contact your Xcel Energy account manager or call 1-888-852-6748 for more information.

Otter Tail Power Company offers a number of ways by which customers can take advantage of their load management capabilities, including:

  • Various energy control options provide 30-50% rate cuts in exchange for allowing Otter Tail to control specific equipment (such as domestic water heating or thermal storage) on their system during on-peak times. Customers can choose whether or not to be notified ahead of events.
     
  • Real Time Pricing Rider is available to a limited number of customers with at least 200 kW of permanent load. Customers pay at the company's real-time rate for usage above and below a historically determined customer baseline load. Otter Tail provides hourly real time prices (RTP) to customers enrolled in this program no later than 4 p.m. the previous day.
     
  • The Off-Peak Water Heating programs provide several money-saving options for customers with separately metered water heaters. Customers receive a credit on the monthly bill in exchange for permitting the utility to directly control their electric water heaters for up to 14 hours per day. These programs may be combined with rebates for new electric water heaters. The Water Heating Credit for Standard General Service allows farm and general commercial customers to receive a monthly bill credit when direct control for water heating appliances is installed. Similar to the Off-Peak Water Heating program, water heaters may be controlled up to 14 hours per day.
     
  • The Deferred Load Rate helps customers save on heating and cooling costs by allowing thermal storage technologies (e.g., electric water heaters) to charge during off-peak hours and still provide service during peak periods when energy control is used. Customers can save up to 30% with the rate. Customers can also use this rate for certain heat pumps and level 2 EV chargers if they are connected to storage.
     
  • The Dual Fuel Rate program allows customers to save on energy costs by switching from an electric heating system to a non-electric backup system during times of peak demand. There are two Dual Fuel Rates, Large and Small, that are dependent on the electric service and metering installed at the facility, one for summer (June through September) and one for winter (October through May).
     
  • The Fixed Time of Delivery Rate delivers electricity only between 10 p.m.–6 a.m. This rate is designed for permanently connected deferred loads with self-contained metering, typically thermal storage space heating or cooling. As with the deferred load and dual fuel rates, there are rate differences between winter and summer, as well aspenalty charges.
     
  • Customers who enroll in Otter Tail's CoolSavings program allow Otter Tail to manage their  cooling usage during peak demand periods. The customer will receive a credit of $6 per ton of controlled cooling load per month during the summer months (June–September).
     
  • Otter Tail customers with a peak demand over 80 kW can also take advantage of the Large General Service Time-of-Day Rate, which provide utility bill savings for shifting electricity usage to off-peak hours, particularly during summer months (June–September).
     
  • Otter Tail offers the Off-Peak Electric Vehicle Rider to customers with electric vehicle chargers. Participants receive heavily discounted electric charging service during the authorized period from 10 P.M. to 6 A.M. each day, though are penalized for charging outside of those hours.

Minnesota Power offers a Commercial Dual Fuel program. This direct load control program is designed for any electric load where a non-electric backup source of energy (e.g., oil as an alternative to electric heat) can be used during periods of peak demand. The incentive is roughly 5 cents per curtailed kWh.

Dakota Electric Association offers several money-saving options through its Energy Wise® Load Management initiative. Full and partial interruption options are available (Rate 70 and 71). The Full Interruption option is offered to customers who manually reduce their connected load to zero during times of peak demand, or let Dakota control the site's generator(s) to achieve the same. The Partial Interruption option is available to customers who agree to reduce their electric load by at least 50 kW during times of peak energy use. Savings are commensurate with the magnitude of curtailment.

Dakota also offers direct load control options for air conditioners as part of its Energy Wise® initiative. On days when energy use is high, Dakota Electric will cycle participants' air conditioner condensers on and off in 15-minutes increments. Option one participants receive a credit of 3.2 cents per kWh for the electricity their air conditioner uses. A rebate of $20 per ton of cooling capacity, up to $1,500, is available to offset the cost of installing a sub-meter and load control receiver. Option two participants have a load control receiver installed by a Dakota Electric contractor and receive a rebate of $6.50 per ton of cooling load each June, July, and August. Dakota Electric also offers a related interruptible program for electric water heaters, which allows participants to receive a reduced price on the electricity their water heater uses.

The Central Minnesota Municipal Power AuthorityMinnkota Power Cooperative, and Dairyland Power Cooperative generation and transmission utilities serving municipal and cooperative utilities in Minnesota offer their members various direct load control and interruptible demand response programs. CMMPA also offers a load bidding option.

Nevada

NV Energy's Cool Share program is currently (Spring 2021) not accepting new applications, but has historically been available to small businesses with air conditioning units of 10 tons or less. Customers earn incentives for allowing direct load control via NV Energy or by controlling their own A/C loads via internet-attached thermostats.

The Interruptible Irrigation Service (IS-2) is available to agricultural customers during irrigation season (March 1–October 31). Irrigation customers on this service must agree to have load control equipment installed on their irrigation pumping. NV Energy will not shut down irrigation equipment except in an emergency situation, in which case the customer will be contacted by NV Energy at least 30 minutes prior to a curtailment event. IS-2 rates are set by the Public Utilities Commission of Nevada on an annual basis.

NV Energy also offers several optional time-of-use rates, which provide utility cost savings for customers who can shift a portion of their electricity use, or peak power draws, away from on-peak hours. These on-peak hours apply to the summer months of July–September in northern Nevada (from 1–6 p.m.) and June–September in southern Nevada (from 1–7 p.m.). Under these rate schedules customers pay substantially less for energy use (or peak power draws) during off-peak hours and more during on-peak hours, especially during summer months.

New Mexico

Public Service Company of New Mexico (PNM) offers two load management programs:

  • The Peak Saver Program, open to large customers on qualifying rates, provides quarterly financial incentives to participants in return for voluntarily reducing the amount of energy they use during peak demand days, typically the hottest days of the year. The size of the incentive paid depends on the amount of electricity committed to the program. These events may occur during any non-holiday weekday from 8 a.m.–8 p.m. from June 1–September 30. PNM is limited to 100 demand response event hours per year. Each event is limited to four hours in duration. Notifications are sent out 10 minutes prior to the start of an event.
     
  • The Power Saver Program offers small business customers (< 50 kW peak) annual payments and a one-time enrollment bonus for allowing the company to either install a Wi-Fi enabled thermostat or connect a load control device directly to their air conditioning units. On selected summer weekday afternoons from June 1–September 30 when electricity demand increases, the Power Saver device receives a wireless signal that puts the air conditioner into a conservation mode.
     
  • PNM also offers time-of-use rates for commercial customers in New Mexico. These rates help customers to save money on their utility bills by allowing them to shift electricity usage to off-peak hours, especially during June, July, and August. On-peak hours are defined as 8 a.m.–8 p.m., Monday through Friday.

Xcel Energy (Southwestern Public Service Company of New Mexico) offers several load management programs:

Participants choose the amount of interruption appropriate for their facility. Remuneration in the form of a monthly credit is based on the maximum annual hours of interruption and the advance notice needed, so there is a wide range of possible savings. Customers may choose either the year-round or summer version of the program, and can join anytime, but most sign up before March 1st for the rate to take effect the same year.
     
  • The Commercial and Industrial Controlled Air Conditioning Rider (Schedule 49) provides energy-saving opportunities for non-residential customers through the use of Xcel-owned load controls on single and/or dual stage air conditioning units of five tons or more. An annual credit per ton is applied to the customer's October bill. Load management events can occur at any time of the year, but are most likely during summer months (June to September) on high demand days. Load management events may occur up to a maximum of 300 hours per year. Customers must agree to load control by Xcel for a minimum of one year.
     
  • The Voluntary Load Reduction Purchase Program (Schedule 60) provides an opportunity for customers with at least 500 kW of peak load during summer months (June–September) that can be available for service interruption by Xcel. Load committed under this program cannot already be committed under another interruptible program or tariff.
     
  • Xcel also offers time-of-use rates for commercial and irrigation customers in New Mexico. These rates provide utility bill savings for customers who can shift electricity use to off-peak hours during the summer. On-peak hours are defined as 12–6 p.m., Monday through Friday, from June–September.
