EPEC’s shareholders, GMS Power Public Company Limited, Marubeni Corporation,
Total Gas & Power Thailand S.A. and China Development Industrial Bank are a strong, synergistic blend of local expertise and international development experience.

The Bang Bo power plant was developed in response to the 1994 Request For Proposals (RFP) for Power Purchases from Independent Power Producers (IPP’s). Under the initiative, EGAT and the Thai government sought private sector involvement and support for the development of new electricity generating projects in Thailand.

The Power Purchase Agreement (PPA) for the project was signed in November 1997, with two further amendments dealing with the after-effects of the Asian financial crisis, the last of which was signed in November 1999. Turnkey Engineering, Procurement and Construction (EPC), and Operation and Maintenance (O&M) contracts were signed with Alstom. In February 2000, contracts were signed to provide approximately US$160 million in non-recourse project financing for EPEC from a consortium of leading local and international financial institutions.

A world-class efficient power plant
At the heart of the 350-MW Bang Bo Combined Cycle Power Plant is the Alstom GT-26 gas turbine, one of the most advanced and fuel-efficient turbines in the world. This allows EPEC to produce power at one of the lowest marginal costs in the entire Thai system and minimises the use of Thailand’s important energy reserves.

The facility is a “combined cycle” power plant, meaning that exhaust heat from the gas turbine is captured and then utilised to create steam in a Heat Recovery Steam Generator (HRSG). This steam then drives a turbine, which, like the gas turbine, is connected to an advanced generator.

This recycling of the energy significantly increases the overall efficiency of the plant and ensures that maximum energy from the natural gas is effectively converted to electricity.

Highest safety and environment standards
The utilisation of clean burning natural gas in the cutting-edge GT-26 turbine ensures that the Bang Bo Power Plant provides world-class environmental protection for the surrounding communities. Air, noise and water emissions from the plant all meet the highest international requirements and are regularly monitored to ensure that the highest standards are maintained. The latest and most advanced treatment facilities and techniques are incorporated into the facility to minimise any impact on the surrounding environment.

EPEC also maintains the highest standards for safety at the plant, as is reflected in the company’s outstanding record in the development of its facility. With over 4.2 million man-hours worked on this challenging and complex project, only 11 accidents occurred with just five serious injuries. Most importantly, there were no fatalities. EPEC is proud of this record and is fully committed to continuing to put “Safety First” in the running of the facility.
