June 21 (Renewables Now) - Powerwall storage system owners in Massachusetts or Rhode Island can now participate in National Grid’s ConnectedSolutions programme which connects home batteries in a virtual power plant (VPP) to support the grid’s operation.
Storage systems will be used to help cut overall electric use during periods of high energy demand.
US electric vehicles (EVs) and energy storage major Tesla Inc (NASDAQ:TSLA), which makes the Powerwall, calculates that battery owners can earn up to USD 700 (EUR 619.5) per year in Massachusetts and as much as USD 1,000 per year in Rhode Island. Powerwall systems paired with enough solar power capacity to completely recharge the battery every day have the greatest potential to earn extra cash, Tesla noted.
Those enrolled in the ConnectedSolutions programme can expect National Grid to request power from their Powerwall for a few hours up to 75 days per year. This includes about 60 summer days and 15 winter days, Tesla explained.
