California Aggregator Seeks Microgrid Hosts as Part of Community Choice Program

Monterey Bay Community Power, a community choice aggregation in California, plans to develop microgrids and Friday released an application seeking customers to host projects.

The solicitation (MGA-01-001) is the first step toward installing one or more microgrid projects in the aggregrator’s service territory: Monterey, San Benito and Santa Cruz counties. After selecting host sites, Monterey Bay Community Power will seek bids, beginning June 7, to identify contractors who can offer turnkey engineering and construction.

California allows cities and counties to form aggregations that provide electricity to customers while the local utility handles transmission, distribution and billing.  Through aggregation municipalities pool their energy loads and leverage buying power. This gives communities not just a chance to buy more renewable energy but to also build microgrids that can increase reliability as well as promote economic development.

“As a local energy model that is rapidly expanding across California, community choice aggregation (models) are well positioned to move beyond the procurement of clean power by also facilitating the development of critical energy infrastructure including microgrids,” says Shawn Marshall, executive director of the Local Energy Aggregation Network, in an interview. “We are seeing this as an emergent area of interest for community choice aggregators, especially in communities that may have grid capacity and/or reliability issues.”

To this point, such aggregation programs work in concert with the local investor owned utility that is domiciled in that area.  The utilities benefit when microgrids alleviate the grid’s stress and congestion, thus improving reliability and maintenance issues.

Moreover, community aggregation programs are carrying out their promise to buy renewable energy. Thus far, they have procured 2,000 MW across the nation and mostly through long-term power purchase agreements.

As for the Monterey Bay Community Power initiative, it is launching the Microgrid SmartConnect Program as a way to support economic development and to provide a resilient power supply to its customers.

“This is a new go-to-market strategy for microgrid development,” says Matthew Willis, manager of energy business development for Monterey Bay Community Power. “For us, it is an economic development play. But it can serve as a model for other places around the country.”

Is it feasible?

In Monterey’s region, for example, there is a large agricultural base. And there is a need for a lot of business expansion to serve the needs of packaging, coolers and products. Customers go to the aggregator and they identify areas where there are grid constraints — anything from where there is congestion to a lack of infrastructure. They ask the aggregator to present a solution.

Monterey Bay Community Power will then look at the feasibility of the site and it will determine the needs and the potential designs. The aggregator can ask for as much as a 50% downpayment on the projected total cost.

The program is now in the process of being rolled out. After a project is constructed, the aggregator will charge a dynamic rate to those customers connected to the microgrid. Customers benefit and ultimately recover their expenses because they are addressing grid constraints and they are able to expand their businesses while receiving a resilient form of power.

Similarly, the Redwood Coast Energy Authority is a community aggregator for Humboldt County. It will use solar-plus-storage to power an airport microgrid in the city of Eureka. The county is interested in reliable electricity for critical facilities. And, given the recent wildfires, PG&E also wants to reduce its reliance on long distance transmission. It believes distributed power with microgrids is an answer.

“We are into the microgrid project because it is one piece of our renewable portfolio strategy and our energy storage development pathway to meet our regulatory requirement,” says Richard Engle, director of power resources for the Redwood Coast Energy Authority, in an interview. “This one project will meet our storage requirement as required by state law.” 

Microgrids are a critical tool to increase the use of renewable energy while gaining more resiliency and improving economic development. Community choice aggregation programs provide the leverage to achieve those goals.
