North American Grid Expansion Boosts Summer Reliability Amid Ongoing Risks

Renewable utility firms across Canada are expanding hydroelectric, solar and wind generation, as well as transmission and distribution networks that support industrial production and transportation corridors nationwide. These infrastructure upgrades are linked to stronger domestic electricity supply for manufacturing and resource‑processing enterprises.

In the United States, the North American Electric Reliability Corporation (NERC) reports a record‑breaking addition of more than 58 GW of on‑peak capacity over the past year, driven largely by solar farms, battery storage and new natural‑gas generators. The surge has improved the grid’s ability to meet summer demand, though the agency warns that elevated risks remain due to accelerated load growth, periods of low wind, heat‑driven demand spikes, and maintenance outages. NERC recommends tighter outage coordination, readiness for extreme weather and ensuring sufficient firm, dispatchable resources to maintain reliability through the early fall and winter seasons.
