The Complete Guide to ZESCO Net Metering in Zambia
ZESCO Net Metering: How to Sell Your Solar Power Back to the Grid
In a landmark move for Zambia’s energy sector, ZESCO Limited officially launched the Net Metering Program. This initiative transforms ordinary consumers into “Prosumers”—individuals who both consume and produce electricity. If you have a solar system at home, you can now feed your excess power into the national grid and receive credits to offset your monthly bill.
What is Net Metering?
Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid.
During the day, most solar systems produce more electricity than the home uses. Under this program, the excess power is exported to the ZESCO grid. Your electricity meter will effectively “run backward” (digitally), and at the end of the month, you are only billed for the “net” amount of power you consumed from ZESCO minus what you provided to them.
The Requirements for Joining
To participate in the program, ZESCO has outlined a specific framework that every applicant must follow:
Grid-Tied Inverters: Your solar system must use a “Grid-Tied” inverter. This technology allows your system to synchronize with ZESCO’s frequency and safely export power.
Bi-Directional Meter: You will need a special meter that can record power flowing in both directions. The cost of this meter is covered by the customer (Prosumer).
Contracted Demand: You can only generate up to the amount of power you are already contracted for with ZESCO.
Legal Agreements: Once approved, you must sign the Net Metering Supply Agreement (NMSA) and the Net Metering Connection Agreement (NMCA).
The Pros and Cons of Net Metering
The Advantages
Lower Electricity Bills: By generating your own power and getting credits for the extra, your monthly ZESCO bill can drop significantly.
Shortened Payback Period: Selling excess power helps you recover the high cost of installing solar panels and batteries much faster.
Energy Sustainability: You are actively helping Zambia reduce its reliance on hydro-power during droughts by contributing clean energy to the grid.
The Disadvantages
Initial Setup Cost: The customer must pay for the application fees and the specialized bi-directional meter.
Account Non-Transferability: If you sell your house, the Net Metering account is closed. The new owner must re-apply from scratch.
Technical Strictness: Only approved equipment (Grid-Tied Inverters) can be used. Older, “Off-Grid” only systems will not qualify for this program.
How to Apply: The Process
Technical Audit: Ensure your solar installer has used a ZESCO-approved Grid-Tied inverter.
Online Application: Visit www.zesco.co.zm and navigate to the Net Metering section to fill out the application form.
Assessment: ZESCO will conduct a technical assessment of your installation to ensure it won’t damage the local grid.
Payment & Installation: Once approved, pay the administrative fees and the cost of the new meter.
Commissioning: ZESCO will install the meter and officially connect you to the Net Metering program.
