The Peruvian utility company Empresa de Generación Eléctrica del Sur (“EGESUR”) has awarded a contract to Wärtsilä to convert the Calana Power Plant from heavy fuel oil (HFO) to natural gas (NG). Wärtsilä has also been given the responsibility for relocating the plant from its current location in Tacna, Peru to Independencia, Pisco in Peru.

The Calana Power Plant is equipped with four Wärtsilä 18V32 reciprocating engines, operating on HFO. The scope of Wärtsilä’s contract covers dismantling, packaging for relocation, transportation, engineering, civil works, mechanical and electrical installation, supply of conversion components, overhaul of the engines, commissioning, start-up, and testing. The plant will enter commercial operation in October 2008.

During 2006, EGESUR took the decision to relocate the Calana Power Plant to Independencia to take advantage of the natural gas supply pipeline coming from the Camisea gas reserves which is a cleaner and lower cost fuel supply. The Independencia Power Plant will supply environmentally clean electricity to Peru’s interconnected North-South national grid.

“This project is a great example of the benefit of investing in Wärtsilä multi-fuel technology when today you may only have access to liquid fuel but tomorrow to natural gas or other price-competitive fuels; thus, assuring your investment does not become outdated”, says Mr. Roberto Lira, Regional Sales Director, Americas, Wärtsilä Services in North America.

“Wärtsilä was selected for its experience in similar conversion projects and demonstrated economic, reliable, and environmentally friendly technology, says Mr. Rudolf Kaufman, Managing Director of Wärtsilä in Peru.

The four Wärtsilä 18V32 reciprocating engines operating on HFO will be converted to a Wärtsilä SG (Spark Gas) model. The engine has ported gas admission and a prechamber with a spark plug for igniting the fuel. The engines will, after the conversion, run on 100% natural gas.
