From 2022 to 2023, WRI convened a cohort of local governments interested in exploring 24/7 carbon-free energy (CFE). Through this cohort, local governments engaged in a series of ten virtual workshops to build a community of practice around 24/7 CFE. Slides from each cohort workshop are posted below. While the content is designed for cohort participants, the materials may be helpful to other local governments and organizations interested in exploring 24/7 CFE.

Cohort Workshops


Workshop 1: Local Government Cohort Kickoff and Introduction to 24/7 CFE

The first workshop provided an introduction to 24/7 CFE; why it is important; why cities are interested in 24/7 or have set 24/7 goals; market experience to date with hourly CFE matching; and approaches and steps cities can take to implement 24/7 CFE. The workshop featured presentations from WRI and Google, who described their commitment and approach to 24/7 CFE.

Workshop 2: Assessing Hourly Loads and Coincidence with CFE

This workshop focused on understanding how hourly load data, grid generation and emissions data, and additional energy procurement data are used together to conduct 24/7 CFE analyses, and what resources and tools are available to collect and analyze these data. The workshop featured presentations from WRI; the city of Boulder, CO; RMI; and Greenlink Analytics.

Workshop 3: Exploring Supply-Side 24/7 Options and Firm Dispatchable CFE

This workshop explored how cities can utilize publicly available data to identify which types of procurement best support their hourly matching goals, how wind and solar generation can complement each other, and how hydropower can contribute to a city’s carbon-free energy resource portfolio. The workshop featured presentations from WRI, Peninsula Clean Energy, National Renewable Energy Laboratory, and National Hydropower Association.

Workshop 4: Integrating Storage into Supply Portfolios 

This workshop examined how local governments can include storage options in a supply portfolio, how the storage market is developing, and how recent federal funding impacts storage deals. It also explored how one buyer structured a value-sharing deal to expand its storage capacity. The workshop featured presentations from the American Clean Power Association and Google.

Workshop 5: Assessing Demand Side Solutions

This workshop identified key opportunities for local governments to shift demand to better align with clean energy production on an hourly basis. It explored emerging research on grid-interactive building technology and highlighted how one leading city is pursuing electrification. The workshop featured presentations from WRI, the Lawrence Berkeley National Laboratory and Luis Aguirre-Torres.

Workshop 6: Emerging Technology Solutions for Hourly Matching

This workshop highlighted a variety of emerging energy technologies and explored how they might be utilized to advance cities’ 24/7 carbon-free energy goals. For two technologies—advanced geothermal and advanced nuclear reactors—experts provided details on the timelines for commercialization, economic comparisons, and safety considerations. The workshop featured presentations from Clean Air Task Force, the U.S. Department of Energy’s Office of Clean Energy Demonstrations, and the Electric Power Research Institute.

Workshop 7: Reporting and Verification Practices for 24/7 Carbon-Free Energy

This workshop provided cohort participants with a deep dive into the key considerations and processes involved in reporting and verifying 24/7 carbon-free energy purchases. Participants also learned how new processes for hourly accounting of community electricity emissions are currently being tested. The workshop featured presentations from Center for Resource Solutions, International Council for Local Environmental Initiatives (ICLEI), and M-RETS.

Workshop 8: Developing an RFP for Hourly Matching of CFE; Assembling Resource Portfolios that Can Match City Loads

This workshop explored many of the important factors for local governments to consider when developing a Request for Proposals (RFP) to meet hourly matching goals. Participants also heard from Jan Pepper (CEO, Peninsula Clean Energy) about Peninsula’s new advanced modeling tool and the findings of their recent research. The workshop featured presentations from World Resources Institute and Peninsula Clean Energy.

Workshop 9: Developing a 24/7 CFE Strategy and Getting to Implementation

This workshop presented pathways and strategies for cities to advance 24/7 carbon-free energy goals. Participants learned how two peer cities are developing internal and external buy-in as they pursue advanced clean energy projects. The workshop featured presentations from C40 Cities, the City of Ann Arbor, MI and Salt Lake City, UT.

Workshop 10: Implementation Challenges and Cohort Wrap-Up

The final workshop centered on the key challenges that cohort members face implementing 24/7 CFE and meeting their clean energy goals. Representatives from three participating local governments shared challenges around working with their utility to develop CFE projects, collecting baseline 24/7 CFE data, and balancing 24/7 CFE investments with current needs. Workshop participants provided feedback and shared relevant experiences. To facilitate open sharing amongst cohort participants, we removed specific speaker attributions from the slides.
