What National Electricity Company does

National Electricity Company (Национална електрическа компания ЕАД / NEK EAD) is a Bulgarian state-owned utility, wholly owned through Bulgarian Energy Holding EAD (BEH EAD), that operates as an integrated electricity company with three core functions: hydroelectric power generation, wholesale electricity trading, and designated last resort supply. NEK owns and operates 31 hydroelectric and pumped storage power plants (HPP and PSPP) with a total installed capacity of 2,739 MW across four major cascade systems — Belmeken-Sestrimo-Chaira, Batatski Vodnosilov Pat, Dospat-Vucha, and Arda — making it the largest producer of green electricity in Bulgaria. Its pumped storage portfolio provides grid balancing, frequency regulation, and energy storage services to the Bulgarian transmission system operator (ESO EAD).

NEK generates revenue through three primary streams: (1) sale of generation output on the regulated and free markets via the Bulgarian Independent Energy Exchange (БНЕБ), covering day-ahead, bilateral contracts, and intraday segments; (2) regulated supply to end consumers under its statutory Last Resort Supplier obligation, with prices set by the Energy and Water Regulatory Commission (KEVR); and (3) balancing energy and system services provided to ESO EAD. Ancillary revenue lines include issuance of Guarantees of Origin for renewable electricity and professional vocational training through its licensed ЦПО Зелена енергия center.

The company is undergoing a multi-year infrastructure rehabilitation program, most notably the restoration of PSPP Chaira in partnership with Toshiba, with hydropower unit No. 3 receiving Act 16 commissioning approval on June 10, 2026, adding 420 MW back into the grid. NEK also maintains a portfolio of Projects of Common Interest (Yadenitsa, PSPP Batak, PSPP Dospat) that may attract EU co-financing. Its operating geography is exclusively Bulgaria, and its customer base spans end consumers, wholesale traders, and the national transmission operator — all within a regulated, state-supervised framework under Bulgaria's Ministry of Energy.

Direct peers

• Verbund AG: Austria's largest hydroelectric utility and a leading European pumped storage operator. Direct comparable in hydro-focused business model, cascade operations, and grid balancing services, though in a more developed market.
• Statkraft: Norwegian state-owned renewable energy company, the largest generator of hydro power in Europe. Operates significant pumped storage capacity and provides flexibility services - directly comparable to NEK's hydro and PSPP operations.
• Hidroelectrica: Romanian state-owned hydroelectric producer with comparable fleet of hydro and pumped storage plants. Both are vertically integrated state utilities focused on hydro generation, grid balancing, and supply obligations in their respective national markets.
• Elektroprivreda Srbije (EPS): Serbian state-owned electric power utility with large hydro and lignite generation fleet. Closest geographic and structural peer to NEK as a neighboring Balkan state utility with similar operational scope and challenges.
• Public Power Corporation of Greece (PPC): Greek state-controlled vertically integrated utility with significant lignite, hydro, and increasingly renewable generation. Operates as a regional Southeast European state utility with similar public supplier and grid balancing roles.

Broad incumbents

• ČEZ Group: Czech state-controlled vertically integrated utility with diversified generation mix including hydro. Larger and more diversified than NEK but operates under a similar Central/Eastern European state-influenced utility model.
• Energias de Portugal (EDP): Iberian vertically integrated utility with significant hydro generation in Portugal and renewable energy operations across Europe. Comparable hydro-anchored business model with European utilities footprint.
• EDF (Électricité de France): French state-owned vertically integrated utility with the largest hydro fleet in Europe. Similar state-owned integrated utility model with hydro, pumped storage, and regulated supply obligations, though at much larger scale.
