Turboden expands into the Asian geothermal power market

Source: Turboden

Turboden started an innovative 6 MW geothermal power plant in Japan in June 2015, and have been selected as official technology provider of a 50 MW geothermal Organic Rankine Cycle system in the Philippines.

Turboden, a group company of Mitsubishi Heavy Industries (MHI), leader in Organic Rankine Cycle (ORC) turbogenerators for distributed power generation employing renewable sources and waste heat, announces the successful operation of an innovative 6 MW (gross) geothermal power plant in Japan.

The plant has been built in cooperation with Mitsubishi Heavy Industries for the largest geothermal power generation developer in Japan.

The plant, commissioned in June 2015, is the first Turboden plant in Japan, fed by a two-phase geothermal resource at ca. 140°C. In particular, after the separation, the steam phase condenses in the evaporator, while the preheater receives only a liquid phase.

For this project, Turboden supplied its highly efficient ORC turbine and process engineering along with commissioning and start-up of the plant.

Along this growth in the Asian market, Turboden has recently been selected to supply a 50 MW (gross) geothermal plant in the Philippines.

Last September Turboden, in consortium with the Spanish Company TSK, has been awarded the turnkey construction of the 50 MWe geothermal power plant in Oriental Mindoro: four ORC turbogenerators will deliver electric energy to the local Electric Cooperatives, ORMECO and OMECO.

Emerging Power Inc (EPi) is the first private investor in Renewable Energy in The Philippines, aiming at a total installation of 300 MW portfolio in the next three years. The listed miner Nickel Asia Corporation (NAC) is the major shareholder of EPi.

The plan provides for full completion of the 50 MW capacity, before the end of 2017, which consists of different project phases.

Turboden turbogenerators will be installed at two different well pads where geothermal source is separated into steam and brine before feeding the ORCs. Turboden has tailored optimized machines according to the characteristics of the geothermal source, of the ambient condition and of the environment.

The organic fluid expands into a multistage axial turbine, a proprietary technology of Turboden, in order to produce mechanical power and then electricity through the alternator. The organic fluid was selected to maximize the efficiency.

Turboden 35 years’ experience in the construction of ORC turbogenerators made it possible to construct units from 1 MW to 20 MW per single shaft with high performance as well as high reliability, and with low maintenance and operational costs.

Turboden’s geothermal fleet currently accounts for 11 plants (99 MW), located in Turkey, Europe, the Philippines and Japan. Overall Turboden has more than 310 ORC plants worldwide (ranging from Australia to Canada) of which more than 260 are already operational with a capacity installed of around 340 MW (further 160 MW are under construction), with an estimated cumulative working time of more than 7 million hours.
