What Glitre Energi does

Glitre Energi, operating commercially as Å Energi, is Norway's largest power company and a vertically integrated energy group headquartered in Drammen and Kristiansand. The company was founded in 1999, building on hydropower operations with more than a century of operational history, and operates across the full electricity value chain: hydropower generation producing 13 TWh annually, regulated grid distribution serving 432,000 customers, and retail electricity supply to both residential and business end users. It is privately held and structured around three core customer-facing brands — VIBB (residential retail), Å Entelios (business and Nordic B2B), and Å Invest (investment/venture activities).

The company's core technology footprint is anchored in large-scale Norwegian hydropower assets, supported by an asset portfolio that includes district heating and cooling, hydrogen, solar, offshore wind, and battery storage. Since 2025 it has layered AI capability onto its hydropower operations to improve production planning and asset performance. The company is investing more than 3.5 billion NOK into the historic Åseral hydropower development, of which Øygard kraftverk is a component, indicating a multi-year capital deployment program extending its generation base.

The business model combines three revenue mechanisms: wholesale power sales from owned generation, regulated grid distribution tariffs within its concession area, and retail electricity margins on supply to end customers. The regulated grid layer provides predictable, concession-protected cash flow, while the retail and B2B layers (320,000 residential plus 9,000 business customers) layer on margin and optionality. Expansion into adjacent energy vectors and the June 2026 Vardar acquisition agreement point to a deliberate diversification of the revenue base beyond traditional hydro and grid economics.
