EGCO Group's advantages are contractual rather than technical: its long-term power purchase agreements pass through the full projected fixed costs, its debt financing charges, and the major maintenance charges used in the tariff calculation. As of June 30, 2010, the company held a 12.72% share of the Thai market, with 3,836.60 MW of plant capacity sold to EGAT through long-term PPAs.

EGCO Group was Thailand's first independent power producer, a company established on May 12, 1992.

EGCO Group faces two principal company-specific risks: its foreign exchange result, which comes from translating foreign-currency net debt into Thai Baht at period end, and lower electricity sales at the Rayong plant, BLCP, and GPG, in line with their PPAs, which drove the profit decline.

Thailand's energy ministry is weighing fuel diversification toward coal, nuclear, LNG, and renewables as domestic natural gas reserves decline.

EGCO Group supplies electricity and steam to the Electricity Generating Authority of Thailand and to industrial customers under 25-year long-term power purchase agreements and power and steam sales contracts, generated from natural gas, LNG, coal, biomass, hydropower, solar, onshore and offshore wind, fuel cells, and battery energy storage.

EGCO Group maintains a total equity capacity of 6,945 MWe across plants in operation and under construction. Its midstream power business serves as the core operation, supplying the majority of the group's revenue and operating profit.
