How do you apply for Net-Metering?
Complete and submit the necessary documents.
Processes and requirements have been updated based on Energy Regulatory Commission (ERC) Advisory dated September 22, 2025.
Requirements a. Application Form Download a copy of the application form here.
Additional supporting documents may be requested to ensure safety, technical compliance, and accurate evaluation of your application.b. Certification of Final Electrical Inspection (CFEI) This will be issued by your Local Government Unit (LGU). As documentary requirements may differ per LGU, applicants are strongly encouraged to coordinate early to prevent processing delays.
The CFEI will be submitted after inspection of your service entrance and before we replace your meter (if applicable).
c. Amended Net-Metering Agreement (NMA) Meralco will provide a copy of this Agreement to you. Note that notarization is NOT MANDATORY and electronic signatures are allowed. d. COC Application Fee Upon receipt of the Statement of Account from ERC, you may pay through the following:
- Pay online via the ERC-LBP Link.BizPortal. (Please provide proof of payment to Meralco, as these will be included in the documents to be submitted to ERC.)
- For payments made via Manager's check*, visit the Meralco Business Center handling your application. Ensure that the Manager’s Check should be payable to "Energy Regulatory Commission".
- For payments made in cash*, visit the Meralco Business Center handling your application.
*Meralco will remit payments to ERC.
Other Requirements / Fees Notarized affidavit and waiver for NM customers on REC meter installation Applicable only if the customer chooses not to install a REC meter. Difference in Meter Cost (DIMC) fee This covers the difference in cost between your old meter and the new bi-directional meter.
The cost shall not exceed Three Thousand Philippine Pesos (P3,000.00) for residential customers (based on Energy Regulatory Commission (ERC) Resolution No. 15 Series of 2025).
Please settle this for the energization, testing, and commissioning to proceed.
Invite us over for a technical evaluation
Meralco will evaluate your application and requirements through the Distribution Impact Study (DIS), to find out the potential effect of your solar installation on our distribution system. If the DIS results show an upgrade of the distribution facilities is needed, a Distribution Asset Study (DAS) will be conducted. DAS fees will be determined depending on the asset study conducted to assess the needed solution to accommodate the RE installation.
To determine the maximum allowable capacity of the solar panel for the RE systems to be integrated without causing adverse effects to the distribution network. Refer to the table below:
Transformer (kVa) Hosting Capacity (kWac) 10 7 kW 15 7 kW 25 10 kW 37.5 14 kW 50 19 kW 75 29 kW 100 38 kW This table only represents the aggregate maximum allowable capacity for solar PV systems per transformer level. Meralco conducts its final assessment depending on actual system conditions.
This is only applicable for single-phase distribution transformers. For other transformer types, it will require transformer loading and/or actual field measurements to assess the hosting capacity.
This hosting capacity is only applicable within the Meralco franchise area.
Hosting Capacity (HC) is defined as the maximum solar PV systems that can be integrated without causing any adverse effect on the normal system operation of the distribution network. The existing MERALCO HC quantification is based on worldwide models and methodologies. The MERALCO HC method properly modeled the low voltage network, secondary line, and service drop, load, and solar PV generation system. An appropriate power flow method was used and was based on the backward/forward sweep radial power flow algorithm coded in MATLAB platform.
Consult your Meralco representative for further details.
Schedule an inspection with us to get final approval
We will also inspect your facility and service entrance to ensure compliance to standards. Once approved, we will install your bi-directional and Renewable Energy Certificate (REC) meter (optional) and conduct the testing of the interconnection of your solar PV in our system.
Meralco to energize your RE system
Once we have replaced your existing meter with a bi-directional meter, installed a REC meter (optional) and have successfully tested and commissioned your solar PV system, you can now safely use and enjoy the benefits of your solar Net-Metering installation in powering your home.
