Virtual power plant aggregator Swell will organize a new VPP in Sacramento Municipal Utility District (SMUD). The My Energy Optimizer Partner+ program aims to bring 20 MWh and 10 MW of renewable capacity to SMUD by recruiting, installing and aggregating capacity from residential customers’ batteries located in the utility’s service area.
The program has the opportunity to scale to 54 MWh and 27 MW over the term of the partnership. Contract capability is based on a 2-hour deliverable capacity, inclusive of exports with day-ahead notification for up to 240 events per year.
“As more SMUD customers add solar panel systems paired with battery storage solutions, they’ll be better able to manage their own energy needs while making meaningful contributions toward reducing their community’s carbon footprint,” said Lora Anguay, Chief Zero Carbon Officer of SMUD. “We are excited to partner with Swell to make this program a reality in 2023 and continue to deliver on our decarbonization plan, which promises environmental protection, excellence in grid resiliency and reliability, affordable rates, and local economic and workforce growth opportunities that benefit the entire region.”
Currently, there are approximately 600 customer-sited energy storage systems in SMUD’s service area, with an additional 400 in the interconnection process and thousands more projected over the next several years. The success of programs like the My Energy Optimizer Partner+ is based not only on total enrollment but also on the additional job opportunities created for local installers and on the socially equitable impact of the program. Accordingly, SMUD has committed to funding batteries for low-income customers in the service area through local non-profits such as Grid Alternatives.
“We’re honored to work with SMUD towards the achievement of their Carbon Zero 2030 plan through the deployment of a multifaceted virtual power plant across SMUD territory and the overall CAISO grid,” said Suleman Khan, CEO of Swell Energy. “Our collaborative virtual power plant will provide real-time energy management and synchronized battery dispatch across SMUD’s customer base, enabling large-scale renewable deployment and minimizing the need for conventional power plants in the region. We believe this model is a beacon for how municipal utilities and other publicly owned utilities can achieve scale and value with distributed energy resources.”
My Energy Optimizer Partner+ will launch enrollments in Q1 of 2023, with operations planned to start in April 2023. Enrollment will be open to both new and existing solar and storage customers. Customers on SMUD’s Solar and Storage Rate can optimize onsite energy usage by pairing solar with energy storage.

This is the type of “thing” that forces the installation company to think ahead to give the customer the “best information” on such a program and the components needed to effectively interface and supply grid services as a “2-hour deliverable capacity…”, provider. I’ve come acrossed many articles where some of those commenting state they have at least 20kWh of ESS and some have even said they have (4 Power Walls). The cost of grid services is a moving target and during one such “emergency” generation/distribution period one might make $2/kWh,… $10/kWh, for grid regulating services. What would the (min/max) of average demand use compared to the cost of a Smart ESS? At the basic level this puts focus on the size of the backup battery pack(s) and size and function of the ancillaries like, is the inverter small as in 3kWh or less output or is it larger like 12kWh and perhaps two units set up to allow a Master/Slave inverter output that could serve 24kWh if need be. At 24kWh and two hours, one would need 48kWh of available energy storage and one would also have to add capacity and resilience to maybe have a 60kWh to 100kWh battery pack storage capacity. Right now a smart ESS can be around $1,100/kWh to around $700/kWh installed. Prices need to come down to one third of this to make long term use sense. Another technology point is expandable architecture. You could start out with a smaller system and enhance energy storage over a period of time as electricity rates go up. This type of design takes some up front thought as to both the customer’s specific (duty cycle) each day on average and cost of electricity from the grid and local utility. SMUD or not, the bottom line for the retail residential consumer is to buy a system that is (flexible), expandable, and allows the residential consumer the ability to cut out the [middleman] in their daily energy needs.
