The Department of Energy (DOE) announced that several renewable energy (RE) and energy storage system (ESS) projects have secured system impact study (SIS) endorsements that evaluated the project’s viability for connection to the national grid.
For the month of June, the DOE granted SIS endorsements to 15 RE projects and two ESS developments. Among the RE projects, ten are wind energy projects, four are solar, and one is hydropower. The two ESS projects are battery energy storage systems (BESS).
These projects will now undergo a grid impact study to determine their feasibility for connection to the transmission grids operated by the National Grid Corporation of the Philippines (NGCP).
Several wind facilities received endorsements, including the 260-megawatt (MW) Mauban onshore wind project in Quezon, the 1,264 MW Roxas onshore wind project in Oriental Mindoro, the 500 MW Cebu wind energy project of Philippine New Energy Development, Inc. (PNDC), the 49 MW Panaon wind project in Southern Leyte, the 300 MW Aurelius wind project in Zambales, and the 500 MW San Roque onshore wind project in Oriental Mindoro.
Additionally, Econergy Renewable Power Philippines, Inc. secured three grid impact studies for its projects: the 200 MW Sorsogon 2 wind project, the 150 MW Camsur wind project in Camarines Sur, and the 100 MW Northern wind project in Northern Samar.
Aside from wind energy, several solar projects also attained SIS endorsements, namely Aboitiz Solar Power, Inc.'s 168.9-megawatt direct current (MWdc) Calatrava solar project in Negros Occidental, Joy-Nostalg Solaris, Inc.'s 62-megawatt peak (MWp) Ajuy 1 solar project in Iloilo, the 112 MW Lian Batangas solar project in Batangas, and the 92 MWp San Manuel solar power plant in Pangasinan. In hydropower, Alsons Energy Development Corp. received clearance for a study for its 8.8 MW Siayan 1 hydropower plant (HPP).
The endorsed projects also include two battery energy storage systems (BESS) from Upgrade Energy Philippines, Inc.: a 25 MW BESS in Isabela and another 25 MW BESS in Samar.
The DOE has also awarded Certificates of Endorsement (COE) to the Energy Regulatory Commission (ERC) for three solar projects: the 72 MWp Luntal solar project of Citicore Solar Batangas 1, Inc., the 92 MWp San Manuel solar plant in Pangasinan, and the Bulacan 3 solar plant of Citicore Solar Bulacan, Inc. Only one conventional plant, the 5 MW Solong EPSA Diesel power plant of Sunwest Water and Electric Co., Inc. (SUWECO), was granted a COE. These certificates signify that the facilities comply with DOE policies and will proceed to ERC evaluation.
