Solar power firm SunPower and utility Consolidated Edison are to collaborate on a virtual power plant pilot project in the US state of New York.

In a statement released this week, the companies said they plan to bundle ‘hundreds’ of Sunpower’s rooftop solar photovoltaic (PV) systems with battery energy storage units from Sunverge Energy, and sell the aggregated output to over 300 residential customers.

The virtual plant will feature 1.8 MW of solar power capacity and around 4 MWh of energy storage, the two firms said, making it the nation’s largest residential distributed energy storage project.  

The project is a result of New York’s Reforming the Energy Vision (REV) initiative, designed to integrate renewables into the state’s grid.

Howard Wenger, SunPower’s president, business units, said:  ‘Increasingly, SunPower is working with forward-thinking utilities to integrate advanced energy solutions and enable the transition to a more sustainably powered world.’

Sunverge CEO Ken Munson added: ‘Solar plus storage facilitates innovative new approaches for utilities to serve customers, including alternative tariff structures and virtual power plants.’
