The Clean Coalition's vision

From 2025 onward, at least 25% of all electricity generated from newly added generation capacity in the United States will be from local renewable energy sources.

Staging Community Microgrids

A key part of getting to 25% local renewables, Community Microgrids provide an unparalleled trifecta of economic, environmental, and resilience benefits to communities.

Unleashing wholesale distributed generation

To get to 25%, we're working to unleash a vastly untapped market in the US, wholesale distributed generation (WDG) — often commercial-scale solar.

Our programs work

Creating groundbreaking models

The Clean Coalition designs and stages cutting-edge Community Microgrid projects that can be replicated in any utility service territory. By showcasing the value and feasibility of these projects, and the vast potential for siting distributed energy resources in the built environment, we’re helping proliferate clean local energy.

Grounding our work in real-world projects

At the Clean Coalition, we base our work on concrete project experience. The projects we design highlight the regulatory and policy issues that are impeding the development of clean local energy projects, and the tools and best practices needed to overcome those barriers.

 

Our policy work

Removing barriers to clean local energy

California is poised to bring significantly more clean local energy online. But some serious hurdles remain. The Clean Coalition is working to overcome these — streamlining the front-of-meter (FOM) or wholesale distributed generation (WDG) interconnection process, helping plan for more FOM projects on the grid, and fixing the system for assessing Transmission Access Charges.

Showing the value of clean local energy

Currently, the full value and benefits of FOM projects are not recognized and compensated in procurement processes. The Clean Coalition is working to fix this. In addition, with our unique combination of technical, economic, and policy expertise, we’re showing that solar+storage can cost-effectively obviate the need for gas peaker plants.

The Clean Coalition now accepts cryptocurrency donations

  • Crypto donations to support clean local energy will help ensure that energy used for crypto is increasingly clean — essentially like local solar offsets for energy-related emissions.
  • Clean local energy like rooftop solar is decentralized energy and similar to decentralized finance — essentially the energy equivalent of DeFi.
  • The proliferation of clean local energy provides resilience that is similar to the unparalleled integrity of a robust blockchain.
