Wartsila has signed a five-year operation and maintenance (O&M) agreement for two power plants in East Timor.

The agreement follows on a previous contract signed in 2012.

Under its terms, Wartsila will continue to operate and maintain the 119 MW Hera and 136 MW Betano gas-fired plants.

The Hera plant (pictured), located in the north of the country near the capital Dili, came online in 2011. The Betano plant is located in the south and came online in 2014. Wartsila supplied the gensets and related equipment for both plants, as well as for the country’s 17.3 MW Inur Sakato power plant, which Wartsila also maintains.

The company said the contract includes real-time plant monitoring and training of local staff.

Virgilio Guterres, director-general of Electricidade De Timor Leste (EDTL), said the contract “will help us to ensure stable electricity supply” in the country.

“As the technology provider of the Hera and Betano power plants,” he added, “Wartsila was the best candidate to support our vision of future’s power plant operation by local Timorese.”

Wartsila has also announced a second renewal of a five-year operations and maintenance agreement, this time with India’s Arkay Energy (Rameswarm) Ltd.

The contract covers O&M for the 150 MW gas-fired Arkay Energy plant in Ramanathapuram, Tamil Nadu.

Wärtsilä’s services include scheduled and unscheduled maintenance of the plant’s 16 34SG gas engines, auxiliaries, waste heat recovery boilers and steam turbine as well as a 110 KV switchyard. The scope also includes manpower services, spare parts and consumables, Wartsila said.

James Rajan, Wärtsilä’s Director of Services Unit, South Asia, added: “The Arkay Energy plant is located in a remote location. We support Arkay Energy by providing them with our quality services which include complete operations and maintenance at the site and remote monitoring support from our Chennai Office. This helps the customer achieve the desired reliability and efficiency, while meeting the expectations of all stakeholders, including their end-customers, authorities and the local community.”
