Retailers and end-users

HERON is a Group of companies engaging in the production, supply and trading of electricity. The HERON Group, focusing on the production and supply of electricity, is one of the few vertically integrated undertakings in the sector, having been the first private Group to operate in the Greek liberalized electricity market. It owns and has successfully operated since 2004, two gas-fired power plants outside Thiva, with a total installed capacity of almost 600 MW.

HERON constructed the first private power plant in Greece in 2004, followed by the second, combined cycle power plant in 2009, at the same site. Having started its operations in 2000, it is now supported by three large energy Groups. HERON was established by the GEK TERNA Group, which is a leader in energy production from conventional and renewable (RES) sources in Greece and abroad. ENGIE (ex GDF Suez), i.e. the largest independent electricity producer and supplier in the world, entered its list of shareholders in 2009. Moreover, QATAR PETROLEUM (through QPI GAS & POWER OPC.), i.e. yet another global leader in the energy sector, successfully acquired a holding in the share capital of the HERON II power plant in March 2014. HERON provides substantial support to Greece’s security of supply, its plants using state-of-the-art technology and operating in line with market needs. On the supply side, HERON is the largest independent electricity retailer owning an ever-increasing household customer portfolio together with a historical legacy of an extended B2B clientele. Thanks to its strong shareholding and production & retail basis, the Group is able to ensure significant and long-term benefits to its customers and partners.
