Yokogawa Wins Control System Order for Maibarara Geothermal Power Project in the Philippines

Tokyo, Japan - January 17, 2013

Yokogawa Electric Corporation announces that its subsidiary, Yokogawa Philippines Inc., has concluded an EPC*1 contract with Maibarara Geothermal, Inc. (MGI)*2 for the design, supply, delivery, installation, testing, and commissioning, of the instrumentation and control systems for the Maibarara geothermal power plant and steamfield facilities. The contract was awarded on December 4.

The Maibarara power plant will have a total output of 20 MW and is being constructed in Batangas province, which is on Luzon Island. This is the first renewable energy project to be carried out under the Renewable Energy Act of 2008, and the first geothermal power station to be constructed on Luzon in 16 years. The initial commercial approval for this project was granted to MGI by the Department of Energy in November 2011, and MGI is targeting initial testing of the integrated power facility by July 2013, with commercial operations by the fourth quarter of 2013.

For these new facilities, Yokogawa Philippines will deliver the CENTUM*® VP integrated production control system and field instruments such as FOUNDATION™ fieldbus-compatible DPharp differential pressure/pressure transmitters for the balance of plant (BOP) facilities and the fluid collection and reinjection system (FCRS). In addition, a PRM*® field device management package will be provided to enable remote, real-time management of these instruments.

Geothermal energy can generate a stable supply of electricity throughout the year because it is not dependent on weather conditions. Also, as no fuels are burned aboveground and only extremely small amounts of carbon dioxide are released, it is environmentally friendly. As such, it is seen as an attractive alternative to fossil fuel power generation. The systems and instruments to be installed in geothermal power plants must be durable and capable of operating in extreme conditions that include the presence of corrosive gas. In addition to meeting all these requirements and being backed by Yokogawa's engineering and service network in the Philippines, the systems and instruments supplied by Yokogawa allow remote monitoring, diagnosis, and adjustment of devices in the field. This supply win can be attributed to Yokogawa's superior technology, the company's extensive engineering and service network in the Philippines, and a strong track record of providing the systems and instrumentation for four geothermal plants in the Philippines, including the Northern Negros Geothermal Power Project.
