Turning Oranges to Apples: A Cutting-Edge Price Comparison for Renewables

A new, comprehensive approach is now available for evaluating renewable energy project revenue and value holistically. Stakeholders increasingly compare renewable energy technologies based on prices from auctions and power purchase agreements (PPAs), but such face-value price comparisons can be misleading. Auction and PPA prices are often not directly comparable because they come from different value frameworks, jurisdictions or points in time, each reflecting their own markets, taxes, and regulatory environments.

To facilitate more meaningful comparisons, researchers from the U.S. Department of Energy (DOE) and the National Renewable Energy Laboratory (NREL)—in collaboration with international researchers working under the International Energy Agency’s Wind Technology Collaboration Programme—have developed a new approach that uses project revenue and value assessments to facilitate improved “apples-to-apples” comparisons between projects and against established cost metrics.

Read the article in Joule to learn more about how the approach evaluates project revenue and value holistically and about its application to eight global offshore wind projects.

National Offshore Wind Research and Development Consortium Announces Offshore Wind Supply Chain Roadmap Project

On May 13 at the Business Network for Offshore Wind’s International Partnering Forum, DOE Acting Assistant Secretary Kelly Speakes-Backman announced the launch of a comprehensive U.S. offshore wind supply chain roadmap project in partnership with the National Offshore Wind R&D Consortium, NREL, Business Network for Offshore Wind, State of Maryland, and New York State Energy R&D Authority. The project will gather data through the Supply Chain Connect tool—a database, or information clearinghouse, used by developers to search for suppliers and by vendors seeking to introduce themselves to industry. Once the data are robust, NREL will evaluate the results and carry out a detailed analysis of current resources and gaps. The project will also characterize the benefits of strengthening the domestic supply chain and leveraging existing strengths.

“Offshore wind will be an important element of meeting President Biden’s goal to achieve a 100% clean energy economy with net-zero emissions by 2050,” said Kelly Speakes-Backman, DOE’s Acting Assistant Secretary for Energy Efficiency and Renewable Energy. “This project will help us develop a robust domestic offshore wind supply chain that will support tens of thousands of good-paying jobs and spur significant national and regional economic growth.”

DOE and Industry Partner to Ensure Cybersecurity for Wind Energy Systems

WETO and Office of Cybersecurity, Energy Security, and Emergency Response (CESER) have announced the formation of a national Wind Cybersecurity Consortium. The Consortium convenes NREL and six leading wind industry organizations to improve the cybersecurity of the U.S. wind fleet through collaborative analysis, development, and information sharing.

The public-private consortium will identify use cases and develop a platform to improve intelligence on wind energy threats and address the need for focus on the potential risks and consequences of cyber intrusions on wind turbines and their systems and controls. Consortium activities will align with strategies and goals from WETO’s Roadmap for Wind Cybersecurity and CESER’s Multiyear Plan for Energy Sector Cybersecurity.

Departments of Interior and Energy Enter into Cooperative Agreement to Advance Offshore Energy Safety and Environmental Sustainability

As part of the Biden-Harris Administration’s commitment to improving the safety and environmental sustainability of offshore energy development, DOE and the U.S. Department of the Interior’s Bureau of Safety and Environmental Enforcement have entered into a cooperative agreement with Texas A&M Engineering Experiment Station. The university will support the ongoing operation and maintenance of the Ocean Energy Safety Institute (OESI). OESI will manage a research program in support both traditional energy, as well as offshore wind and marine and hydrokinetic energy technologies.

New Modeling Tool Helps Maximize Wind Farm Power Production and Reliability

Researchers at NREL have developed FAST.Farm, a new modeling tool for predicting the power performance and structural loads of wind turbines within a wind farm. An extension of the OpenFAST open-source wind turbine engineering tool, FAST.Farm considers the physics of farm-wide ambient wind in the layer of the atmosphere in which wind turbines operate, changes in wake shape with downstream distance, wake movements caused by background turbulence, and farm-wide control. With FAST.Farm, users can simulate the conditions each turbine in a wind farm will need to withstand throughout its lifetime, or they can start fresh and design an entire wind farm to achieve minimal structural load and maximum power production.

FAST.Farm is now available through OpenFAST on GitHub.

Halfway to Zero: Progress towards a Carbon-Free Power Sector

Sharply reducing carbon emissions is imperative to prevent the worst effects of climate change. Yet even in the power sector—often viewed as the lynchpin to economy-wide decarbonization, and where low-carbon solutions are increasingly plentiful and cost effective—the pace and scale of the required transformation can be daunting.

A wind turbine is reflected on solar arrays.

A review of historical trends, however, shows the progress the power sector has already made in reducing emissions. Fifteen years ago, many business-as-usual projections, such as in the Energy Information Administration’s 2005 Annual Energy Outlook, anticipated that annual carbon dioxide (CO2) emissions from power supply in the United States would reach 3,000 million metric tons (MMT) in the year 2020. In fact, direct power-sector CO2 emissions in 2020 were 1,430 MMT—roughly 50% below the earlier projections. By this metric, in only 15 years the country’s power sector has gone halfway to zero emissions. At the same time, electricity  bills are lower, costs to human health from air pollution are lower, climate damages from carbon dioxide emissions are lower, and the number of energy jobs is higher than previously projected.

Some factors that have contributed to this success include broad changes to the economy, energy efficiency, more wind and solar power, continued operations of the nuclear fleet, and switching from coal to gas. Achieving a net zero power sector may be challenging, but if the past is any guide, it suggests that further deep reductions are possible.

Experts Predict 50% Lower Wind Costs than they did in 2015

Wind energy has realized accelerated cost reduction over the last five years—both land-based wind and offshore wind. Recent DOE-funded research gathered input from 140 global experts on technology advancement and cost-reduction opportunities. The work follows a similar expert survey conducted in 2015. The DOE-funded 2020 research shows that experts now expect land-based and offshore wind costs to decline ~35–50% by 2050, resulting in costs 50% lower than predicted in 2015. According to the findings, turbine scale is a key driver for cost reduction. Wind turbines are expected to be 2–3 times larger by 2035, with a median of 5.5 MW for land-based turbines and 17 MW for offshore turbines. As costs decline, industry focus will turn to enhancing the value of wind in energy markets, e.g., through hybridization with storage, and to overcoming deployment barriers. If realized, these expected advancements, cost reductions, and value-enhancement measures will enable wind to play a larger role in energy supply and power-sector decarbonization than previously anticipated.
