The Southwest Power Pool (SPP) can reach 90% renewable energy while keeping US electricity rates stable, according to a study by Brattle Group.
Researchers recommended that transmission system operators consider adopting grid-forming battery energy storage systems system-wide to improve grid stability and to maximize system hosting capacity for solar and wind generation.
A new study says that more solar power would be used to charge electric vehicles in the United States if inexpensive level-1 chargers were deployed at workplaces, and rate design favored daytime charging.
Wider use of electric heat pumps to heat buildings creates a larger market for renewable energy, but also presents challenges, which can be met through building insulation and weatherization, cold climate heat pumps, thermal energy storage systems, and higher-voltage distribution grids, a report says.

Replacing existing transmission lines, known as conductors, with advanced conductors could enable 764 GW of transmission-connected solar by 2035. However, some US utilities are slow to adopt this technology. In a recent webinar, two utilities that have used advanced conductors for years shared their experiences.
The Sierra Club, an environmental group with a focus on reducing fossil fuel pollution, has graded 75 American utilities on their resource plans through 2035. The average grade was a “D.”
Firebrick heat storage technology, not batteries, will be used to store energy for industrial process heat in a 100% renewable energy system, says a study out of Stanford University.
A new U.S. Department of Energy loan guarantee will help finance 200 MW of solar and 285 MW of grid-scale storage on the island.
The National Institute of Standards and Technology has flagged a cybersecurity risk for smart inverters, and is developing guidelines to prevent cyberattacks.
