AEDC serves Nigeria’s capital territory and four surrounding states, covering the highest concentration of government buildings, diplomatic missions, and institutional facilities in the country. The FCT Abuja alone hosts federal ministries, the National Assembly, the Presidential Villa, international embassies, and a growing commercial sector in districts like Wuse, Maitama, Garki, and Gwarinpa. For solar installers, AEDC territory offers a unique market: government and C&I clients with reliable payment histories, high energy costs, and strong incentives to reduce diesel dependence.
This guide covers the AEDC solar connection process: territory confirmation, application requirements, technical standards, protection settings, metering arrangements, and the specific considerations for government building installations. Use solar design software that includes NEMSA equipment data to avoid specifying unapproved inverters.
Government Buildings Need Federal Clearance Before AEDC Approval
Solar installations on federal government buildings in the FCT require clearance from the Federal Ministry of Power or the Bureau of Public Enterprises before AEDC will process the connection application. This clearance is separate from AEDC’s technical approval and can add 2–4 weeks to the timeline. Start the federal clearance process before submitting to AEDC.
AEDC Service Territory
AEDC’s franchise area covers the political capital and surrounding states:
| State / Territory | Major Areas | Solar Market Profile |
|---|---|---|
| FCT Abuja | Wuse, Maitama, Garki, Gwarinpa, Kubwa, Lugbe, Jabi | Government, diplomatic, commercial, residential estates |
| Nasarawa | Lafia, Keffi, Akwanga, Karu | State government, education, agriculture |
| Kogi | Lokoja, Okene, Idah, Ankpa | Transport corridor, state institutions |
| Niger | Suleja, Kontagora, Bida, Minna (part) | Government, education, small commercial |
| Kaduna (part) | Zuba, Madalla corridor | Peri-urban residential, border trade |
AEDC operates zone offices in Abuja (central), Lafia, Lokoja, and Suleja. The Abuja central office handles the majority of C&I applications due to the concentration of commercial and government buildings in the FCT.
Net Metering Under AEDC
Residential Net Metering (Below 50 kW)
Residential customers in AEDC territory can apply for net metering:
- Meter type: Bi-directional smart meter with 30-minute interval recording
- Billing: Export credited against import on a monthly basis
- Surplus export: Carried forward or compensated at NERC-approved export tariff
- Application: Submit through AEDC customer portal or at the CBD head office
- Timeline: Meter upgrade typically 2–4 weeks after connection approval
Commercial Net Metering (50 kW – 1 MW)
Commercial systems follow the same framework with additional requirements:
- Metering: Commercial-grade bi-directional meter with remote monitoring
- Protection: Full NERC protection relay specification
- Load study: AEDC may require a load flow study for systems above 100 kW
- Export limit: AEDC may impose an export limit based on local transformer capacity
Self-Generation Exemption
C&I systems below 1 MW for own consumption do not require a NERC licence, but AEDC still requires:
- Pre-connection notification
- Technical approval
- Bi-directional metering
- Compliance with NERC protection standards
C&I Solar in AEDC Territory
The C&I solar market in AEDC territory is driven by three factors:
Government buildings: Federal ministries, departments, and agencies (MDAs) in Abuja are under pressure to reduce energy costs and diesel consumption. The FCT Administration has issued directives encouraging solar adoption on government buildings.
Diplomatic missions: Embassies and international organisations in Maitama and Asokoro require reliable power and have budgets for quality solar installations.
Commercial developments: Shopping centres, hotels, and office complexes in Wuse, Garki, and Gwarinpa face grid supply of 6–10 hours per day and diesel costs of ₦300–₦450/kWh.
| Customer Type | Typical System Size | Key Consideration |
|---|---|---|
| Federal ministry | 100–500 kW | Federal Ministry of Power clearance required |
| Embassy / diplomatic | 50–200 kW | High reliability requirement, quality equipment |
| Hotel | 100–300 kW | 24-hour load, battery sizing critical |
| Shopping centre | 200–800 kW | Peak cooling load, export potential |
| Residential estate | 20–100 kW | Shared infrastructure, metering complexity |

Abuja Has the Most Reliable Grid Supply in Nigeria
AEDC’s FCT network typically delivers 8–12 hours of supply per day in central Abuja districts (Maitama, Wuse, Garki), significantly better than most other Nigerian cities. For solar system design, this means smaller battery banks are needed for hybrid systems compared to Lagos or Ibadan. However, grid voltage fluctuations are common — ensure inverter voltage ride-through settings are configured for AEDC’s actual grid behaviour, not just the nominal specification.
Generate AEDC-Ready Solar Connection Documentation
SurgePV produces NERC-compliant single-line diagrams, protection settings tables, and system specifications formatted for AEDC pre-connection notifications — reducing documentation time for installers across Abuja, Nasarawa, Kogi, and Niger states.

Frequently Asked Questions
Does AEDC allow grid-tied solar without net metering? Yes. A grid-tied solar system can operate without net metering if the customer does not want to export surplus power. The inverter is configured with zero-export control, and a standard meter upgrade may not be required. However, AEDC still requires pre-connection notification and technical approval for any grid-interactive system.
Can I install solar in an AEDC area without notifying AEDC? No. Any grid-interactive solar system in AEDC territory must be notified before commissioning. Operating a grid-tied system without AEDC approval violates NERC technical standards. Fully off-grid systems (no grid connection) do not require AEDC notification.
What is the cost of AEDC’s solar connection approval? AEDC charges an administrative fee for processing pre-connection notifications. As of 2026, fees range from ₦50,000 for residential systems to ₦200,000 for commercial systems above 100 kW. Government buildings may have a separate fee schedule. Confirm the current fee with AEDC at submission.
Does AEDC inspect the site before approving solar? For residential systems below 50 kW, AEDC typically approves based on documentation review. For commercial systems above 50 kW and all government buildings, AEDC may conduct a site inspection to verify the connection point and assess feeder capacity. The inspection is scheduled after the initial documentation review.
