The N.C. Clean Energy Technology Center (NCCETC) released its 2024 annual review and Q4 update edition of The 50 States of Solar.
The quarterly series tracks state regulatory and legislative discussions and actions on distributed solar policy.
The Q4 report finds that 47 states, plus the District of Columbia and Puerto Rico, took some type of distributed solar policy action during 2024. The greatest number of actions were related to net metering policies, residential fixed charge increases and community solar. From these policy actions, the authors noted the top ten most active states along with trends in policy making.
“Following a period of relatively little activity, 2024 saw the reemergence of requests for large fixed charge increases,” noted Brian Lips, senior project manager at NCCETC. “Starting with California, where the Commission approved income-graduated fixed charges, multiple utilities requested increases of 100% or more.”
