Improve transmission planning and interconnection cost allocation, says SEIA-affiliated group

Federal regulators should consider specific reforms to improve transmission planning, lower interconnection costs and provide cost certainty, says a group affiliated with the Solar Energy Industries Association.

Reconductoring could enable 764 GW of transmission-connected solar by 2035

Replacing existing transmission lines, known as conductors, with advanced conductors could enable 764 GW of transmission-connected solar by 2035 even if transmission in new corridors was limited, found a study by UC Berkeley and GridLab researchers.

DOE aims for national collaboration to deploy advanced grid technologies

Advanced conductors and energy storage are among the technologies that have substantial potential to increase transmission capacity, says a Department of Energy “liftoff” report.

Allow solar developers to choose “connect and manage,” says DOE roadmap

To speed interconnection of utility-scale renewables and storage projects, a U.S. Department of Energy roadmap sets forth 35 solutions and proposes actions to implement the solutions. The roadmap was developed through a DOE stakeholder process known as i2X.

Puerto Rico’s solar net metering law at risk from federal oversight board

Puerto Rico led the nation in per-capita residential solar installations last year, but continued progress is threatened because a law extending solar net metering through 2031 has been challenged by a federal oversight board.

Renewables and storage interconnection backlog grew about 30% last year

The wait for transmission interconnection studies constitutes a “major bottleneck” for solar, storage and wind projects, which accounted for over 95% of all active capacity awaiting studies at the end of 2023, Lawrence Berkeley National Laboratory has reported.

Citizens groups criticize TVA’s decision to build a 1.5 GW gas plant

TVA decided not to choose solar and storage despite 15 GW of such projects in its interconnection queue. TVA’s board of directors could overturn the gas plant decision, said an environmental law group spokesperson.

Give distributed resources a greater role in grid reliability, say four law professors

Distributed solar and storage, along with demand response, “perform during extreme weather events” and deserve a greater role in reliability planning, the law professors say, while a new public office of grid reliability could guide transmission planning.

DOE funds heated sand energy storage project pilot

A modeled commercial-scale project storing energy in heated sand could produce 135 MW of power for five days. The U.S. Department of Energy is funding a pilot project intended to demonstrate commercial viability.

Rural electric co-ops lend money to customers to improve energy efficiency

Some rural electric cooperative utilities allow customers to pay off energy efficiency improvement loans through their utility bills. That contributes to energy efficiency’s role in the renewables transition.
