Distributed Energy Resources

Distributed Energy Resource (DER) Overview

Distributed Energy Resources (DER) are power sources connected to the distribution system or electrical system of end-users that could be aggregated to meet demand for energy.

On 29 November 2022, the Energy Regulatory Commission (ERC) Resolution No. 11, Series of 2022, “A Resolution Adopting the Rules Governing Distributed Energy Sources (DER)” also known as the “DER Rules”, was published in a newspaper of national circulation and took effect on 14 December 2022.

The DER Rules cover three (3) types of installations:

  1. DERs utilizing renewable energy (RE) sources for end-user systems connected on-grid and are meant for consumption and export, with nameplate capacity of greater than 100kW up to 1MW, but maximum capacity to export capped at 30%;
  2. DERs utilizing renewable energy (RE) sources for end-user systems connected off-grid and are meant for consumption and export, with nameplate capacity not greater than 1MW, and maximum capacity to export also capped at 30%; and
  3. DERs utilizing any energy generation and storage technology, whether on- or off- grid, and meant for end-user consumption only, so long as the DER owner and end-user are not the same entity.

Technologies such as microgrids, EVs, net metering, stand-along battery energy storage systems, etc. that are covered by other regulations are not covered by the DER Rules.

*Nameplate capacity refers to the maximum rated output of an electric power equipment.

Net Metering (NM), Zero Export (ZE) and Distributed Energy Resources (DER)

NM, ZE and DER: The brighter, safer way to use renewable energy. As the world leans towards cleaner and more sustainable energy, Meralco takes the initiative in supporting the use of renewable and small grid sources of energy.

Currently, the most readily available and widely used is solar energy. Including Meralco in your solar energy plans ensures that your installation is compatible with the power grid, as it will not endanger you or your customers, and that it can be properly monitored to make sure that you get the maximum value and savings from your investment.
