What is Net-Metering?
Net-Metering is a program under 2008 RA 9513, the Renewable Energy (RE) Act. It allows customers to install an RE facility within their premises up to a capacity of 100kWp. Any excess electricity not consumed in the home or business is exported to a distribution utility (in this case, Meralco). In return, Meralco compensates customers through credits in their monthly bill.
100kWp is the ceiling established under the Energy Regulatory Commission's (ERC) Amended 2019 Net-Metering Rules. Any RE installation above 100kWp is no longer covered by the Net-Metering program. As such, the RE installation will fall under the Zero Export (ZE) or Distributed Energy Resources (DER).
