Who We Are

Energy Development Corporation is a geothermal energy industry pioneer and the recognized world leader in wet steam field technology. In the Philippines, EDC is the largest vertically integrated geothermal company, delivering 1,475MW of clean and renewable energy. We continue to diversify our renewable energy portfolio through investments in hydropower, solar power and wind energy projects in the Philippines. With almost 40 years of geothermal mastery, EDC is set to deliver the benefits of sustainable geothermal development to communities around the world as it ventures into Latin America and Indonesia.

EDC is part of the First Gen Corporation (“First Gen”) Group, which has the largest portfolio of power plants using clean and renewable technology in the Philippines. First Gen’s 16 power generation plants have a combined capacity of 2,763MW. First Gen has one of the cleanest power portfolios in the country with its entire power generation portfolio utilizing fuels such as geothermal steam, water, and natural gas.

Wind power complements EDC’s existing power generation assets including the baseload geothermal plants, as well as, the Pantabangan hydroelectric plant, which serves as a peaking plant.

EDC has become the leading geothermal energy producer in the Philippines through the successful development and operation of numerous geothermal energy projects. Since 1983, the Company has successfully developed, financed, built, and operated seven geothermal steamfields in five geothermal contract areas, containing both wet and dry steam. These steamfields currently supply geothermal steam to geothermal power plants with an aggregate installed capacity of 1,130 MW. In addition, the Company currently, directly and indirectly, owns and operates eleven geothermal power plants with a total installed capacity of 1,181 MW. EDC, through its indirect wholly owned subsidiary Green Core Geothermal, Inc., operates the 192.5MW Palinpinon and 112.5MW Tongonan geothermal power plants. Bacman Geothermal, Inc., another indirect wholly owned subsidiary of EDC, operates the 130MW Bacman geothermal power plant. The Company believes this track record has enabled it to develop the expertise needed to assess the feasibility of future acquisitions and greenfield projects, ensure the safe and efficient construction of power plants, and provide for efficient power plant operations.


We will become the global leader in geothermal energy as we strengthen our leadership in the Philippine renewable energy industry.

Our Strategy

Our vertically integrated operation primes us for global geothermal leadership as we acquire prime geothermal concessions in Chile, Peru, and Indonesia. We will partner with like-minded international companies that are eager to bring reliable and clean base-load electricity to their customers. As we decisively move into the international market, we will establish our credibility as a clear partner of choice in the long-term development and management of geothermal projects.

On the home front, we will increase our wind energy generation capacities while we maintain our position as the Philippines’ premier geothermal company. Our 150MW wind power project in Burgos, Ilocos Norte commissioned in 2014 is the biggest wind farm in the country. In the next 10 years, we will add 230MW to our geothermal portfolio with our five frontier geothermal projects. We have eight greenfield concessions with a mix of geothermal and wind in the exploration stage. We are also seeding investments in solar energy, aside from continually developing pursuits in hydropower.

We will strengthen our partnerships with customers from the Luzon, Visayas, and Mindanao power grid markets by assuring them of value-added services in a reliable, systematic manner.
