U.S. authorities find no definitive evidence of hidden devices in Chinese solar inverters
New documents reveal U.S. government found two cases of communications in Chinese inverters that differed from official documentation. The discrepancies were deemed “non-malicious” and “non-intentional” by investigators.
How to build a balcony solar kit to UL certification
UL Solutions has released design standards for balcony solar, also known as plug-in pv, along with whitepaper highlighting three main risk categories of balcony solar in the US consumer market.
Ohm Analytics 2025 VPP market report reveals 21% growth in overall capacity
Ohm analysts tracked over 150 actions taken by utilities, regulators and legislators in 2025 and noted a 153% year-over-year increase in residential battery enrollments, with ample room to grow.
EG4 Electronics partners with Leap to expand VPP offerings
The collaboration will integrate Leap’s distributed energy platform with EG4’s hardware ecosystem, which the companies say will allow homeowners to monetize their energy storage systems through automated grid services while maintaining backup reliability.
2026 National Electrical Code changes: PCS and EMS part 2
Power control and energy management systems (PCS and EMS) are powerful tools that will enable the next generation of electrical systems, and the way they are featured in the 2026 NEC is a testament to the ways they can unlock the capability of distributed energy systems and more fully utilize the capacity of electrical infrastructure.
Grid-forming inverters significantly enhance grid stability, national lab finds
The Kauaʻi Island Utility Cooperative in Hawaii, which deployed storage before grid-forming inverters became available, became a test case for diagnosing grid issues that can arise with older grid-following inverters, and how grid-forming inverters can stabilize a grid.
Big Tech turns to solar and storage to bypass grid bottlenecks
Data center developers are co-locating generation and storage to avoid interconnection queues, as the traditional grid is failing to meet power requirements of generative AI, said a report from Wood Mackenzie.
ERCOT outperformed on interconnection in 2024 likely due to “connect and manage”
More than 25 GW of large-scale generating projects seeking an interconnection agreement in the ERCOT grid region reached that stage in 2024. Berkeley Lab said ERCOT’s “connect and manage” approach “is likely one reason” for the grid operator’s success.
2026 National Electrical Code changes: PCS and EMS part 1
The 2026 National Electrical Code (NEC) introduces a significant shift in electrical design by prioritizing real-time power flow over traditional, often oversized, theoretical worst-case calculations. This evolution centers on the formal distinction between two critical technologies: Energy Management Systems (EMS) and Power Control Systems (PCS), which is explored in part one of this two-part series.
Colorado utility PSCo must offer flexible interconnection for community solar, storage
Flexible interconnection is one of the most impactful, cost-effective tools for enabling distributed energy resource deployment, said a joint filing by the Solar Energy Industries Association and others.
