Grids & Integration

Solar and wind generation continue to expand rapidly while coal is in a tailspin

The EIA’s most recent Electric Power Monthly report shows that solar has accounted for nearly 3.4% of the country’s generation so far in 2020, with wind being responsible for another 8.5%. Meanwhile, coal has plummeted to just 17.8% of the nation’s total, down nearly 30% from just last year.

Duke Energy, developers and regulators advance solar in the Carolinas with ‘queue reform’ and cluster studies

To address developers’ frustrations with its interconnection process, Duke Energy worked with solar industry associations to map out a second proposal aimed at rationalizing its interconnection process in 2022, after the existing queue is cleared.

Interconnection queues across the US are loaded with gigawatts of solar, wind and storage

Texas and California lead the green grid trend, with PJM not far behind. ERCOT has 75 GW of solar in its interconnection queue — but how fast clean energy can displace natural gas and coal remains a key issue.

Can community microgrids fill the gap in California’s plans for 100% renewable energy?

A 10 MW, 40 MWh storage project on the Southern California coastline could provide the first link for a string of community microgrids that, according to the Clean Coalition’s Craig Lewis, could show that high penetrations of distribution-connected solar are entirely doable.
