Solar-plus-storage systems in ordinary households will provide 20MW of energy capacity in New England, with Sunrun announcing the award of a contract from state’s ISO (independent system operator).
Aggregated as a virtual power plant, around 5,000 customer systems will be able to contribute to meeting peaking capacity demand on the network, the most polluting - and expensive - energy on the grid. ISO New England figures forecast peak load between 1 June 2019 and the end of May 2020 of as much as 25,528.391MW during the peak hour of 4pm to 5pm.
While the residential solar leasing company’s initial contribution to the value of the entire opportunity is fairly modest, it is among the largest VPP’s projects announced to date as well as the first capacity contract in the US from an ISO to a home storage operator.

Now in its sixth successful year, Solar & Storage Finance USA is the only event which looks at raising capital for solar, storage and collocated solar and storage projects in the USA. The conference will help delegates understand how providers are evolving propositions for storage and how they can access capital for standalone solar or storage, and co-located projects. Meet debt providers, funders, utilities, corporate off takers and blue chip energy firms with capital to invest and developers with credible pipelines.
