New England’s Wholesale Energy Markets
Front-of-the-Meter (FTM) Opportunities with Stem
Supporting Multiple Value Streams for Customers in ISO-NE
With Stem’s extended project developer support services and Athena®’s ability to deliver multiple value streams, Stem has grown rapidly in the ISO New England (ISO-NE) market since it expanded market participation activities for FTM storage in 2020. As of mid-2021, Stem’s Athena-controlled systems comprised 52% of Massachusetts and 19% of ISO-NE’s operational continuous storage facilities active in the wholesale energy, ancillary services, and forward capacity markets. Athena continues to deliver an average of up to 30% internal rate of return (IRR) for its users.
From early site analysis to managing the bidding strategies using our AI software, Stem’s expertise in wholesale markets ensures our developer partners in ISO-NE achieve their revenue goals.
Across various projects in New England, Stem is enabling its project developer customers to co-optimize value streams – including day-ahead energy markets, real-time energy markets, forward reserve markets, real-time reserve markets, frequency regulation, forward capacity market, Clean Peak Energy Portfolio Standard program, coincident peak reduction, solar shifting incentives, solar ITC earnings, and Solar Massachusetts Renewable Target (SMART).
Why Partner with Stem?
Important milestones achieved by Stem during three recent customer projects in ISO-NE include:
- Athena Bidder™ automated both day-ahead and real-time energy market participation in ISO-NE along with the capacity market and frequency regulation for a project in Haverhill, Mass. Athena uses the most recent forecasts to automatically optimize the battery operations and evaluate what value stream to participate in while respecting constraints such as the point of interconnection (POI) limit, other interconnection service agreement (ISA) constraints, ramp rate restrictions, warranty guidelines, program requirements, and investment tax credit (ITC) constraints at every trading interval.
- In addition, Athena Bidder forecasted market prices and solar generation while continuously delivering market-ready price and quantity bids in the ISO-NE market for a project in Halifax, Mass.
- Separately, Stem’s first direct current-coupled systems, deployed in Leicester and New Marlborough Mass., are expected to begin generating revenue via ISO-NE as well as the state’s SMART and Clean Peak Energy Portfolio Standard programs.
