Advanced macro grid initiative announced, with funding support from Bill Gates-backed group
Bill Gates and Breakthrough Energy see enhanced transmission as facilitating electrification and grid reliability. Increasing transmission development at the “seams” between regions could save consumers more than $47 billion and return more than $2.50 on every dollar invested.
Solar hosting capacity maps must be accurate to be useful
Solar hosting capacity maps, now required in seven states, show where solar can be added on a distribution circuit without incurring any grid expense—but only if those maps are accurate. California’s experience, says a policy paper, shows that best practice guidelines for validating maps are needed to aid state regulators.
Keeping net energy metering credits ‘clean’ in California means adding relays and meters
It’s during the interconnection review and approval processes that most developers run into the NEM integrity issue with California’s big utilities.
