Company overview

ALLETE INC

ALLETE Inc. is a Midwestern energy holding company that owns regulated utilities, renewable power assets, and related services focused on generating electricity and providing grid management; CIK 66756 highlights this diversified portfolio centered on the Electric Services SIC 4911 universe, where the firm delivers reliable generation, transmission, and distribution along with renewable project development to residential, commercial, and municipal customers across Minnesota, North Dakota, and Michigan’s Upper Peninsula. The company’s suite spans base-load coal and gas stations, hydroelectric and wind farms, plus grid modernization and energy efficiency offerings aimed at large industrial accounts and retail consumers seeking flexible, low-carbon solutions. While ALE leans on long-term rate cases to fund infrastructure, it also navigates material risks such as fuel price volatility, hydrologic variability, and regulatory shifts around emissions and clean energy mandates, so investors keep a close eye on its capital plan and compliance posture; latest filing details remain unavailable, so view live SEC filings on Earnings Feed.
