Breaking the U.S. interconnection logjam
Experts at Intersolar & Energy Storage North America 2025 highlight key reforms to accelerate interconnection and reduce project delays.
Consumers will pay billions due to “very slow” interconnection in the PJM grid, study says
Faster interconnection of generating resources waiting in PJM’s queue, nearly all renewables, could have resulted in far lower capacity prices in PJM’s latest auction, but instead consumers will pay for PJM’s high capacity prices, says a study by Grid Strategies.
Solar-friendly policies that states can pursue to control the cost of electricity
Solar-friendly policies that include demand flexibility, advanced conductors and virtual power plants, as well as lesser-known approaches, can help control the cost of electricity, says RMI.
Who’s footing the bill for new transmission?
While the Federal Energy Regulatory Commission’s Order 1920 could provide a step forward, many regions continue to struggle with implementing effective cost-sharing frameworks.
Higher voltage faces greater resistance
Utility-scale solar is set to crank up the voltage, preparing to shift from 1.5 kV to 2 kV on the DC side. It is a move that could redefine PV system design and slash costs, but it won’t happen globally due to vastly different regulations as voltages rise, reports Tristan Rayner.

Battery storage in California delivering as a daily workhorse, details IEEFA report
An institute report details how batteries are now regularly capturing otherwise-curtailed solar generation, and are firmly integral to daily grid operations.
Dynamic line ratings: A smart business decision
Dynamic line ratings allow operators to optimize existing infrastructure by adjusting transmission limits in real-time based on environmental conditions, thereby reducing the need for costly upgrades, minimizing service interruptions and facilitating the integration of clean energy resources.
Building not your average dream home: All things energy
This series describes the process of designing and building a sustainable home, which was all going smoothly until the utility put up a major roadblock by “red zoning” the area.
