Heron S.A. is a power company in Greece. It is a joint company of GEK Terna and GDF Suez, established on 11 December 2008. It owns and operates Heron I and Heron II natural gas-fired power plants in Viotia, about 120 kilometres (75 mi) north of Athens.
Heron I
Heron I is a 147 MW dual-fuel open-cycle gas-turbine plant, which has been in operation since 2004. It was the first private power plant in Greece.
A stand-by diesel generator provides emergency power in case of 20 kV grid power loss. Thus, the power plant is capable of black start operation. The installation also includes:
- Natural gas filtering and pressure reducing station with two streams.
- Natural gas preheating with heat exchanger and two hot water boilers.
- Diesel oil storage facility with capacity 2500 m3 providing inventory for 5 days operation in case that natural gas is not available.
- Raw water storage facility with 2 × 1000m3 tanks and two deep well pumps with capacity 10 m3/m & 20 m3/h each.
- Demineralised water production plant with capacity 2 × 30 m3/h.
- One 500 m3 carbon steel tank with interior lining and six stainless steel tanks 100 m3 each for the storage of the demineralised water.
- Two fire pump skids for raw and demineralized water. Each skid consists of one diesel pump, one electric driven pump and one jockey pump.
- Fire detection and CO2 fire fighting systems for the gas turbine housings.
- Main control building with 20 and 0.4 kV switch boards, MCCs, UPS and batteries and the central control room of the station.
Heron II
Heron II is a 435 MW under construction combined cycle gas-fired power plant. It is scheduled to become operational in 2010. The plant includes STAG 109FB GE main equipment in single shaft arrangement using dry low NOx combustion system.
