In just four years, MCE customers have eliminated 185,751 metric tons of greenhouse gas emissions.
It would take all of the trees in Muir Woods over 300 years to sequester that much carbon!

Why Renewable Energy Matters

Energy is one of the largest contributors to harmful greenhouse gases in the U.S. because so much of it is sourced from fossil fuels. But each of us can do something to change that. MCE’s mission is to make it easier for our customers to choose an electric service that contributes more renewable energy to the electric grid. Turning away from polluting energy sources and toward clean, sustainable energy sources has never been easier or more critical.

Where Our Power Comes From

We procure our energy from clean, renewable sources such as solar, wind, biogas, geothermal, and small hydroelectric. We closely research and monitor our suppliers to ensure that they are using green, responsible practices and sourcing our power from renewable energy providers throughout California, Oregon, and Washington. Not only is our power greener, it’s also as local as possible.

Growing Renewable Development

MCE has signed over 70 energy supply contracts to date, 28 of which are active this year. These numbers will continue to grow. We currently have more than 813 megawatts of new, California renewable energy online and under development for our customers.

MCE and its partners have committed over $1.6 billion to the development of in-state and local renewable energy projects.

Power Suppliers

Developers and owners of renewable energy projects have an opportunity to help fulfill MCE’s future resource requirements through our “open season” process. We also operate a Feed-In Tariff program through which local developers can create and sell small renewable energy projects directly to us at a set price, provided they are located within our service area.

Beginning in 2016, MCE committed to limit its usage of unbundled renewable energy credits (RECs) to a maximum of 3% of its entire energy portfolio.

Renewable energy credits, or “RECs,” are accounting mechanisms used to track renewable energy production and provide proof that electricity has been generated from an eligible renewable energy resource and delivered to the electric grid. One REC represents one megawatt hour (MWh) of renewable energy. This system allows utilities to document their progress towards sustainability goals, such as fulfilling—or in the case of MCE, surpassing—the requirements of California’s Renewable Portfolio Standard program.

There are three types of RECs:

Category 1 (Bundled): RECs are associated and permanently attached (“bundled”) to renewable energy that is delivered from eligible renewable resources within California.

Category 2 (Bundled): RECs are associated and permanently attached (“bundled”) to renewable energy that is generated outside of California—but within the Western Electricity Coordinating Council (WECC)—and “firmed and shaped” upon delivery into the California grid by coupling it with an equivalent volume of energy from an alternative source, typically hydroelectric or natural gas.

Category 3 (Unbundled): RECs are associated with renewable energy that is generated within the Western Electricity Coordinating Council but are not attached to any physical energy. This category of REC allows businesses, organizations, and institutions to claim the environmental benefits of renewable energy generation to help satisfy the sustainability goals or requirements assigned by their local, state, or federal government.

Integrated Resource Plan

We follow an annually updated Integrated Resource Plan to determine our electricity resource needs and guide our procurement process. Our goals include a long-term objective of 100% renewable energy for all customers, as well as short-term goals that set local parameters around electricity procurement and storage. We are aiming to provide our Light Green customers with 80% renewable and 95% carbon-free power by 2025.
