Understanding Clean Energy



Using the Community Choice Energy
model, MBCP is able to source
clean energy at a lower cost

You now have a choice in the energy mix your dollars support. MBCP procures carbon-free and renewable energy on behalf of our Central Coast community, at a savings.

How it Works (Power Supply)

MBCP procures carbon-free and renewable electricity on the wholesale market. Through contracts with our suppliers, MBCP sources approximately 3,400 Gigawatt hours of electricity to serve nearly 95% of the electricity load in our jurisdiction: Monterey, San Benito and Santa Cruz counties as well as the cities of San Luis Obispo and Morro Bay.

The electricity that MBCP purchases is generated along the Western Grid, which is the largest regional grid in the US, spanning from British Columbia in the north, to Northern Mexico in the south, and from California in the west to Colorado in the east. Being connected to such a vast network of power suppliers allows MBCP’s procurement team to secure clean energy at the best possible price to ensure that cost-savings are passed onto our customers.


Energy Source (Power Mix)

Wind, water, and solar sources produce the majority of electricity which MBCP purchases on behalf of our customers. 

Our power mix is made up of approximately 34% renewable energy with the remainder being supplied by large hydroelectric facilities.

MBprime is our 100% renewable service offering, with 50% solar and 50% wind. If you would like to support 100% renewable energy, MBprime costs less than one penny per kilowatt hour more (.8c/kwh more). Would you like to sign up? Go to the Account Services tab. 

In the great state of California, hydroelectric dams bigger than a certain size are no longer considered “eligible renewable” sources, largely because of the environmental impacts on river ecosystems. However, these dams produce no greenhouse gasses when generating electricity and MBCP is committed to supplying carbon free electricity on behalf of our customers. Our renewable energy content is made up of electrons generated from solar power plants, wind farms, geothermal, and small “run of the river” hydroelectric facilities.

When thinking about electricity and where it comes from, it’s important to keep in mind that because of the nature of electrons, it is nearly impossible to track electricity from its source to where it is finally used. This is especially true when considering the size of the Western Grid. MBCP supplies clean power onto the grid and is thereby cleaning up the general power mix of the region. It has become clear that the Community Choice Energy trend is poised to change the status quo and with combined efforts, facilitate the biggest push for clean power in the history of the state.

MBCP's 2020 Carbon-fee Allocation Decision

MBCP customers have been unknowingly supporting the high costs of operating PG&E’s Diablo Canyon nuclear facility by paying their Power Charge Indifference (PCIA) fee. After years of fighting for lower PCIA fees on behalf of our customers, the CPUC recently ruled that our customers are entitled to energy credits referred to as “carbon free attributes,” an offer that would save millions over a 5 year period. 
These credits have already been paid for by our customers which is one of the many reasons MBCP’s Policy Board decided to accept the carbon-free attributes (CFA) on March, 2020.  Following a Special Meeting of the Policy Board on June 10, 2020 where the Policy Board decided to reject the CFA for 2020, MBCP has updated its CFA Decision Fact Sheet:
