The Green Energy Option: what a contestable customer can sign

The Green Energy Option Program is the part of the Renewable Energy Act that lets an electricity customer choose to be supplied from renewable sources. The rules issued by the Department of Energy in 2018 and by the regulator in 2021 opened it to any customer with an average peak demand of 100 kW or more over the previous twelve months. That is most factories and many commercial buildings.

Compiled in September 2026 from the releases of the time, with the revisions the agencies have published since. Nothing here is a forecast.

How it differs from open access

Retail competition and open access lets a large customer, above a demand threshold that was 750 kW in 2023, buy from any licensed retail supplier. The green option lowers the threshold to 100 kW but restricts the choice to suppliers licensed to sell renewable electricity. In both cases the distribution utility still delivers the power and bills for the wires; only the supply changes.

What the contract covers

Energy, at a price the supplier and the customer agree, usually indexed and usually for two to five years.

The renewable energy certificates that prove the source, which the customer may use for its own reporting.

Nothing about availability: the customer is still on the grid and still loses power when the grid does.

What it does not cover

Steam. A green-option contract changes where the electricity comes from and says nothing about the boiler, which in most Philippine plants is the larger energy user. A food plant that signs one has a renewable power supply and a diesel-fired steam supply, and its scope 1 emissions are unchanged.

How the two combine

The sites that get furthest sign a green-option contract for the power they still import and put a residue-fired boiler on the steam. The contract handles the part the grid does well, and the boiler handles the part it cannot. A site that does both has moved its whole energy supply, not half of it.

If your site runs a fuel-fired boiler or produces an organic residue, an energy and waste audit puts your own numbers against this. Tell us about your site and an engineer replies with the data we need. The figures behind each quarter are in the quarterly market brief.
