Publicly listed renewable energy company Alternergy has secured certificates of approval (COA) from the Department of Energy (DOE) for all five projects it submitted under the fourth round of the Green Energy Auction (GEA 4).

The approved projects represent a combined 500 megawatts (MW) of additional generating capacity. These include two onshore wind developments—the Tayabas North Wind project in Quezon province and the Alegria Wind project in Cebu—as well as two aqua-voltaic facilities, the Liberty Floating Solar Phase A and Phase B projects in Tarlac. Also covered by the approvals is the Kalandagan solar plus battery energy storage system (BESS) project in Tacurong City, Sultan Kudarat.

“This demonstrates the readiness of all our projects for full-scale development works and Alternergy’s commitment to bringing these projects to fruition,” Alternergy President Gerry Magbanua said in a statement.

“With all five Certificates of Approval on hand, this is a key milestone that our GEA 4 projects have been formally awarded.”

Magbanua added that the floating solar facility in Tarlac is expected to rank among the country’s earliest large-scale projects of its kind.

“These projects will demonstrate how renewable energy projects can coexist with aquaculture, maximizing land use while supporting food security and strengthening local livelihoods,” he said.

Referring to the Mindanao-based BESS facility, Magbanua noted that the project will highlight the firm’s “growing expertise in battery-integrated solutions following the commercial operations of our Palau + BESS Project in 2024.”

Meanwhile, the two newly approved wind developments will add to Alternergy’s existing pipeline, complementing the Tanay and Alabat Wind Projects, both of which are scheduled for completion within the year.

“These are exciting times for Alternergy. We are expanding our green energy footprint and are committed to driving growth and delivering value to our shareholders,” Magbanua said.
