LCG, May 30, 2025--NuScale Power Corporation (NuScale), a leading provider of advanced small modular reactor (SMR) nuclear technology, yesterday announced that it has received design approval from the U.S. Nuclear Regulatory Commission (NRC) for its uprated 77 MW power modules. NuScale states that it remains the only SMR technology company with design approval from the NRC, and the company remains on track for deployment by 2030, with 50- and 77-MW SMR options.

LCG, May 29, 2025--The U.S. Energy Information Administration (EIA) released an analysis yesterday showing that the California Independent System Operator (CAISO), the grid operator for most of the state, is increasing its curtailment of the rapidly growing solar- and wind-powered generation facilities in order to balance electricity supply and demand, which is necessary to maintain a stable electric system.

Hawaiian Electric Begins Implementation of New Solar Option for Homeowners
LCG, August 5, 2016--Hawaiian Electric Company announced Tuesday that a new kind of rooftop solar system that enables households to generate their own electricity and to potentially store energy for when the sun is not shining is now being approved and installed on island homes. The island's first approved "self-supply" rooftop system was recently turned on at a home in Honolulu.
The new, self-supply systems, believed to be the first in the U.S., are now being installed under Hawaiian Electric Companies' Customer Self-Supply Program, an alternative to the popular Customer Grid-Supply Program.
The self-supply systems are designed specifically for the Hawaiian market and use new inverter technology to provide power to the home but prevent any excess electricity from being injected back into the distribution grid. By not allowing injection back into the grid, the utility can avoid pushing physical limits of the distribution system and causing related problems. This concern is more significant in Hawaii, where rooftop solar PV has been rapidly installed. Given Hawaii's Renewable Portfolio Standard (RPS) goal for each utility to achieve 100 percent renewable energy by 2045, solar power generation is likely to continue to increase in Hawaii.
Hawaiian Electric's Senior Vice President of Customer Service stated, "It's been five years since rooftop solar really took off in Hawaii and more than 77,000 customers have made the choice to use it. The shift to self-supply is an important evolutionary step to ensure that the rooftop solar option remains sustainable, cost-effective and available to some of the 85 percent of customers who don't have it."
There is a growing number of self-supply systems available from a number of vendors that now meet the specifications set by the Hawaii Public Utilities Commission (PUC). Hawaiian Electric has been working with these companies to develop standard technical specifications that will qualify systems for an expedited approval and potentially faster installation.
The PUC created the Customer Self-Supply Program as an alternative to the grid-supply program, especially once the grid-supply capacity limits established by the commission were met.
The Customer Grid-Supply program, which credits customers for the excess electricity they send to the grid, remains available on Oahu, though space is going fast. Maui Electric recently reached the capacity limit set by the PUC and Hawaii Island is nearing the limit, but self-supply is available.
