As US states work to address and enable the swift growth of distributed energy resources (DERs), including solar and energy storage, the issues surrounding their interconnection to the electric grid require close attention, Sara Baldwin, VP for regulatory affairs at the Interstate Renewable Energy Council (IREC), explains.

In the UK, the National Grid has recently warned the government that its capacity to supply electricity is at a seven-year low due to recent generator closures, fires and outages. The margin of capacity over demand is expected to be just 4% this winter.
