As distributed energy resources such as residential solar rooftop increase in the next decade, aggregation into virtual power plants could save US utilities up to US$35 billion, according to The Brattle Group.

Hitachi Energy will power the US’ first-ever primary vanadium source entirely from renewable energy in a partnership with Nevada Vanadium.

Battery storage could play the same role on the grid as a proposed 60MW natural gas and fuel oil peaker plant in Massachusetts and not only result in lower emissions but also in cost savings.

Many of the most polluting thermal power plants on the US grid today are also the most lucrative to run, but the service they provide could already be done twice as cheaply using solar and storage, developer 8minutenergy has claimed.
