New England’s Wholesale Energy Markets
Front-of-the-Meter (FTM) Opportunities with Stem
Capturing Energy Storage Value in ISO-NE
With Stem’s extended project developer support services and Athena®’s ability to deliver multiple value streams, Stem’s installed base has grown rapidly in the ISO New England (ISO-NE) market since it expanded market participation activities for FTM storage in 2020. As of early 2024, Stem operates nine fully commercial projects participating in ISO-NE and another 20 projects working towards market participation throughout the year with 12 unique partners.
From early site revenue simulations to managing the bidding strategies using our AI-powered digital platform Athena®, Stem’s wholesale markets expertise ensures our developer partners in ISO-NE achieve their revenue goals.
Across various projects in New England, Stem is enabling its developer partners to co-optimize value streams – including day-ahead & real-time energy, forward & real-time reserve, frequency regulation, forward capacity, Clean Peak Energy Portfolio Standard program, coincident peak reduction, and Solar Massachusetts Renewable Target (SMART).
Why Partner with Stem?
Stem is playing a key role in helping developers get their clean energy projects to the finish line through our extensive experience in project development services, our procurement and supply chain strength, analytical support around technical and economic analysis, project delivery services, and ultimately operating the projects in the market to achieve maximum revenues.
Our best-in-class Athena digital platform drives success under this framework by optimizing the economic and operational trade-offs necessary for optimizing solar and storage portfolios. Athena Energy Management System (EMS) provides an end-to-end supervisory monitoring and controls solution for energy storage and solar assets. It is a comprehensive controls platform encompassing onsite controllers, an optional onsite SCADA solution and cloud infrastructure to deliver complete configuration, monitoring, control, data management and overall performance management capabilities.
Important milestones achieved by Stem during three recent customer projects in ISO-NE include:
- Athena PowerBidder™ automated both day-ahead and real-time energy market participation in ISO-NE while co-optimizing with the capacity and ancillary services markets for a project in Haverhill, MA. By integrating Athena’s AI-powered market price forecasts and bidding engine our partners optimized the battery operations while respecting constraints such as the interconnection service agreement (ISA) constraints, ramp rate restrictions, warranty guidelines, program requirements, and investment tax credit (ITC) constraints at every trading interval.
- In addition to market prices, Athena PowerBidder forecasted solar generation while continuously delivering market-ready price and quantity bids in the ISO-NE market for a project in Halifax, MA.
- Separately, Stem’s first DC-coupled systems, deployed in Leicester and New Marlborough, MA, generated revenue via ISO-NE as well as the state’s SMART and Clean Peak Energy Portfolio Standard programs.
