Heat Wave Tests Grid; Clean Energy and Batteries Help Avert Crisis
**Week of August 17, 2026**
A record heat wave put U.S. power infrastructure under significant strain, but clean energy sources helped the grid avoid catastrophe — a notable real-world stress test. In New York City, plug-in battery units kept renters cool without triggering grid overloads, demonstrating a practical resilience tool for dense urban housing.
On the infrastructure side, ConEd announced plans for 28 new substations by 2035 to support growing electrification demand, including heat pump adoption. Meanwhile, Vermont is incentivizing high-efficiency manufactured homes designed to cut energy use by up to 50%.
On the policy front, the Trump administration's proposed changes to energy efficiency analysis methodology could weaken appliance and equipment standards — a development contractors and manufacturers should monitor closely.
