What should a business verify before proposing a commercial solar-and-battery system at a Nigerian site?(Mar.2025)
A concise pre-screen guide for EPCs and site owners: verify ownership/permissions, electrical and load data, structural and safety constraints, documentation readiness and distribution-company coordination. Identify when detailed engineering studies are required. Require current NERC, site, distribution-company and engineering review before proposal or commitment.

## The practical answer Answer-first: before proposing a commercial solar-plus-storage system at a Nigerian site, verify the regulatory guidance and site-specific facts that will shape feasible designs, documentation needs and coordination steps. Core items to confirm early are site ownership and permissions, detailed electrical documentation and consumption data, structural and siting constraints for panels and a battery cabinet, available space and shading, safety/environmental baseline documents, and which materials local authorities or the distribution company may request. Review current NERC guidance: NERC issues generation licences for on-grid, off-grid and embedded generation categories. Its Generation Licence page describes embedded generation as connected to a distribution network and lists application documentation that can include site evidence, single-line diagrams, plant design information, off-take arrangements, safety/environmental documents and embedded-generation draft agreements. NERC also states that a mini-grid supplies power to more than one customer in a defined geographical area and can operate independently or with a distribution network. Require current NERC, site, distribution-company and engineering review before proposal or commitment. ## Quick checklist - Ownership & permissions: written proof of site control, landlord or company approval and any roof-use conditions. - Electrical documentation: up-to-date single-line diagram, protection settings, switchgear ratings and metering details. - Load data: at least 12 months of interval or monthly consumption, plus identified critical circuits and peak demand periods. - Tariff & billing: current tariff class, time-of-use periods, demand charges and meter type—confirm with facility accounts and the distribution-company contact. - Structural & site survey: roof load capacity, penetration locations, fire routes, drainage and clearances required for a battery cabinet. - Space & shading: orientation, tilt, shading sources and room for future expansion or separation distances for battery equipment. - Access & logistics: vehicle access, crane or lift needs, staging and site security for battery delivery and installation. - Safety & environmental: site hazard inventory, firefighting provisions, hazardous materials on site and any environmental constraints. - Preliminary design inputs: required backup behaviour, battery siting preferences, inverter location and approximate DC/AC sizing target. - Documentation readiness: site photos, floor plans, environmental documents and any existing commercial arrangement drafts. - Coordination: identify the distribution-company contact and note any application or documentation processes they require. - Budgeting for studies: allow scope and time for protection coordination, short-circuit and load-flow studies and structural analysis. ## When engineering review is essential - No complete single-line or protection data is available. - Multiple service points, parallel generators or legacy complex electrical systems exist. - Limited rooftop area, heavy shading or weak roof structure constrain layout options. - Integration with critical loads or uninterruptible power requirements is planned. - Metering, tariff structures or consumption records are unclear or disputed. - Any safety, hazardous-material, flood or fire risk affects siting, ventilation or spacing. - The distribution-company or regulator indicates specific documents or studies may be requested. Require current NERC, site, distribution-company and engineering review before proposal or commitment.
