ERC Approves P2.8 billion Alternergy Tanay Wind Project massive 500kV Interconnection

​The Energy Regulatory Commission (ERC) has greenlighted the massive 500 kV integration of Alternergy’s 128MW Tanay Rizal Wind Power Project into the Luzon transmission backbone. This follows a similar ERC approval earlier this month for Alternergy’s Alabat Wind Power Project.

​In its decision, the ERC approved the application of Alternergy Tanay Wind Corporation (ATWC), a subsidiary of Alternergy Holdings Corporation (ALTER), to develop and own a dedicated point-to-point transmission facility. This involves constructing two (2) double circuit, 500 kV transmission line and a 33/500 kV switchyard with a 1 x150 MVA transformer, at a cost of P2.8 billion.

The ERC also approved a unique two-stage interconnection scheme comprising of an interim and a final connection. As an interim connection scheme, the ERC approved a bus-in connection to the existing 500 kV San Jose-Tayabas transmission backbone of the Luzon Grid, pending completion of the proposed Baras 500 kV Substation of the National Grid Corporation of the Philippines (NGCP), which is the final connection scheme. In its decision, the ERC also directed NGCP to expedite the filing and completion of the NGCP Baras 500 kV Substation.

“This is an innovative interconnection scheme that enables our Tanay Wind Power Project to meet its commitment under the Administration’s Green Energy Auction 2 (GEA 2),” said Gerry P. Magbanua, ATWC president. “We are thankful to NGCP for its collaboration in ensuring our timely dispatch of green power to the grid while awaiting the final connection scheme.”

Mr. Magbanua also expressed appreciation to the ERC, led by newly appointed Chairman Francis Saturnino Juan, highlighting the back-to-back approvals for Alternergy’s wind projects.

“With NGCP and ERC’s support, our interconnection schemes for our Tanay and Alabat Wind Power Projects demonstrate Alternergy’s capability to design innovative solutions to critical transmission access for renewable energy infrastructure,” he said.
The Tanay Wind Power Project is part of Alternergy's portfolio of renewable energy projects, supporting the company's Road to 500 MW capacity goal by 2026.

Alternergy is a renewable power pioneer with a portfolio of project companies engaged in different RE projects, particularly wind, run-of-river hydro, solar farm and commercial rooftop, battery storage and offshore wind projects. With robust expansion plans in the next two years, Alternergy aims to develop up to 500MW of additional wind, solar, and run of river hydro projects.

Alternergy’s management team is comprised of a pioneering group of RE advocates led by former energy secretary Vince Pérez, Gerry Magbanua, Knud Hedeager, Eduardo Martinez Miranda, Michael Lichtenfeld, Atty. Ina Arriola, Annette Rafael and Carmen Diaz.

Alternergy ("ALTER") debuted at the Philippine Stock Exchange as the first initial public offering (IPO) in March 2023. In August 2024, ALTER has been included in the PSE Industrial Index. In December 2024, ALTER issued first dividend payments to its preferred shareholders, including the Government Service Insurance System (GSIS) in the amount of P118 million.
