April 26, 2023: How to Determine Hosting Capacity on the Bulk Electric System

Distribution utilities in more than a dozen states offer publicly accessible hosting capacity maps, allowing developers of distributed energy resources to identify favorable and unfavorable locations before applying to interconnect, saving some of the time and cost for all stakeholders. Despite these potential benefits, hosting capacity methods are not widely applied on the bulk electric system (BES). This meeting highlighted technical challenges for implementing such maps in BPS and identify novel approaches to overcome such challenges.

May 3, 2023, 2-4 p.m. ET: Distribution System Protection with High DER Adoption Levels  

Record amounts of distributed energy resources (DER) have changed the nature of fault currents and relay coordination on distribution systems. Some of the conventional solutions have included direct transfer trip, de minimus DER levels on urban secondary networks, and forced disconnection whenever the feeder is reconfigured. These methods have limitations for both DER and the utility. This exchange discussed newer methods that might work better, and identify pathways to adoption.

August 2, 2023, 2-4 p.m. ET: Defining Distribution, Sub-transmission, Transmission, and the Bulk System for Interconnection

What is sub-transmission? It’s important to know when applying to connect generation, or study such an application, at a location that might be classified as sub-transmission. Of the many terms in use to describe transmission, distribution, or sub-transmission, only “bulk electric system” is rigorously defined, leaving much room to interpret other terms. As the grid becomes more complicated and less hierarchical, the interconnection community needs to find better ways of cooperating.

July 19, 2023, 2-4 p.m. ET: Collecting and Considering Feedback in Public Policy

Evidence is mounting that the United States is shifting toward a focus on equity and energy justice. Renewable interconnection policies play an important role in that shift. The U.S. Department of Energy (DOE) Justice40 Initiative launched in early 2021 and directs 40% of the overall benefits of certain Federal investments to flow to disadvantaged communities. Several states have also been centering equity and energy justice in recent years. This territory may be new for some policymakers and actors, but is well tread for advocates. This Solution e-Xchange focused on merging those worlds through collaboration. Watch a recording of the meeting and download the presentation slides (PDF).

May 31, 2023, 2-4 p.m. ET: Limitations and Barriers to Improving Pre-Application Data Transparency

Previous i2X Solution e-Xchanges have highlighted the need for increased data prior to the submission of an interconnection request in order to reduce developer uncertainty and mitigate the need to submit exploratory requests. This meeting will unpack the limitations and barriers to making such data more transparent and accessible. Pre-application data may include, for example, data on transmission or distribution headroom (i.e., hosting capacity), data on estimated or historical upgrade costs by location, and detailed generator equipment data needed by transmission providers to run models. This meeting will feature shared content and breakout sessions across both distribution (DER) and transmission (BPS) interconnections.

July 6, 2023, 2-4 p.m. ET: Opportunities to Improve Accessibility and Standardization of Post-Application Interconnection Queue and Cost Data

Data on interconnection processes, timelines, and upgrade costs are crucial to enable third-party analysis, auditing, and to assess the efficacy of implemented reforms. Yet, the publicly accessible data currently provided through interconnection queues lacks details that are important to understanding key trends and interconnection barriers and are not well standardized across grid operators. Interconnection cost data, in particular, is very difficult or even impossible to access at the project-level, making any compilation and analysis of cost trends extremely costly and challenging. This e-Xchange explored opportunities to improve the transparency, accessibility, and standardization of interconnection process, timeline, and cost data in order to inform, assess, and improve interconnection procedures going forward.
