Alternergy Holdings Corporation (PSE: ALTER), a company that builds clean energy power plants in the Philippines, has just turned on its second renewable energy facility in 2026. According to a disclosure filed with the Securities and Exchange Commission on March 23, 2026, the company announced that its 5-megawatt (MW) Dupinga Hydro Power Plant in Gabaldon, Nueva Ecija has started commercial operations.

What Does This Mean?

Think of a power plant like a giant battery that makes electricity for homes and businesses. But instead of using coal or oil that can pollute the air, this power plant uses flowing river water to create electricity – which is much cleaner for the environment.

The Dupinga facility is what’s called a “run-of-river” hydro power plant. This means it uses the natural flow of the river to spin turbines and generate electricity, without needing to build a large dam that floods big areas of land.

Alternergy’s Growing Energy Portfolio

This is actually Alternergy’s second renewable energy plant to begin operations in 2026. Earlier in February, the company started running its 28-megawatt-peak (MWp) Balsik Solar Power Plant in Hermosa, Bataan. That facility uses solar panels to capture sunlight and turn it into electricity.

The Dupinga project is being operated through Alternergy’s subsidiary company called Dupinga Mini Hydro Corporation (DMHC). A subsidiary is like a smaller company owned by a bigger parent company.
