Vertically integrated solar PV company SunPower and residential battery storage provider sonnen have each started up programmes to deploy solar-plus-storage for communities in California and New York respectively.
Talen Energy, a US independent power producer (IPP) with a 13GW portfolio of generation assets, has contracted energy storage developer Key Capture Energy to install a battery storage system at the site of a coal power plant in Maryland.
A residential virtual power plant (VPP) programme in Maryland has received regulatory approvals, enabling a partnership between technology provider Sunverge and utility Delmarva Power to get started on the project.
While interconnection queues for America’s electric transmission and distribution operators are “swelling up” with growing numbers of energy storage projects, some of the big challenges ahead include enabling fair market participation for both standalone storage and storage paired with generation.
Decision-makers across Canada now recognise the value that energy storage can bring to the grid, with Ontario’s grid operator establishing its first-ever set of market rules for energy storage’s participation.
The CEO of US virtual power plant provider Swell Energy has said that New York utility company Con Edison has been “very progressive” in recognising the value that aggregated home battery systems paired with solar can offer.
The battery storage market in the UK has become a viable investment opportunity in just the past few months, even without the backing of long-term contracts for grid services, according to an investment manager in the renewable energy sector.
