Projects

Every project is a problem solved

We document our work the way we design it: what the client faced, what we engineered, and what changed. No inflated portfolios — delivered work is marked delivered, and concept-stage initiatives are labelled exactly that.

Hybrid Solar Power System — Maitama, Abuja

Client: Private residence Location: Maitama, Abuja Scope: Design, installation, commissioning
Challenge
Rising electricity costs and unreliable grid supply were forcing continuous generator dependence.
Solution
We designed and installed a 10kW hybrid solar PV system with lithium battery storage — rooftop generation, intelligent inverter control and seamless switching between solar, storage and grid.
Impact
Grid electricity dependence reduced by over 80%. Supply reliability improved across all critical loads, and operating costs fell from day one.

Concept-stage initiatives

These are initiatives we are actively developing — clearly labelled concept stage. They represent where 87 Engineering intends to direct its capability, and we welcome partners, financiers and programme operators who share these priorities.

Concept Stage

Kaduna Agricultural Mini-Grid Initiative

A productive-use-first mini-grid concept for an agricultural community in Kaduna State — pairing solar generation and storage with irrigation, cold storage and agro-processing loads so the grid pays for itself through what it enables.

Concept Stage

Community Solar for Primary Healthcare Centres

Standardized solar-plus-storage systems for primary healthcare centres, designed around vaccine cold chains, delivery-room lighting and diagnostic equipment — with an O&M model built in from the start.

Concept Stage

Solar-Powered Education Initiative

Reliable power for schools: lighting, digital classrooms and evening study capability, engineered as replicable packages that education programmes can deploy at scale.

Concept Stage

Clean Energy Markets Programme

A market-development concept connecting mini-grid supply with SME demand — structuring tariffs, appliances financing and technical support so clean energy becomes commercially self-sustaining.
