Talk to usWhy now
Diesel is now an operating risk, a reporting risk and a policy target.
Generators were the answer to an unreliable grid. Fuel cost, mandatory climate disclosure and national transition policy have turned them into a liability that boards have to explain.
70.7%
of Nigerian firms own or share a generator. Outages cost businesses about 3% of annual sales.

The choice
Three ways to deal with diesel. Only one removes the capital outlay and the performance risk.
The technology is similar in each case. What changes is who pays up front, who carries the performance risk, and who answers for the emissions line in your disclosure.
Institutional load does not stop when the grid does. Today, diesel covers the gap.
How it works
We carry the programme from survey to reporting.
You provide site access and the existing utility connection. Assessment, capital, procurement, installation, operation and reporting sit with us.
- 1
Assess
We meter load, grid hours and actual diesel use at each site, and size the system to measured demand.
- 2
Finance
We raise and carry the capital with our financing partners. No capital outlay from you.
- 3
Build
Tier 1 storage and solar, installed by qualified Nigerian EPC partners under independent engineering oversight.
- 4
Operate
We own, monitor and maintain the assets for the life of the agreement. Performance risk stays with us.
- 5
Report
Metered, site-level diesel displacement and emissions, delivered on a schedule built for external assurance.
What happens after you get in touch
No commitment until a proposal is on the table, and your site information stays under a signed confidentiality agreement.
- Within two working daysIntroductory call. We learn about your sites and generator estate.
- Before any dataMutual confidentiality agreement. Signed before site details change hands.
- About ten working daysDesktop review. We review your diesel records and site list and propose the sites to meter.
- 2 to 4 weeksSite baseline. We meter diesel use, run hours and load at each agreed site.
- ThenProposal. A site-by-site design and an energy price set against your measured diesel cost.
Diesel and emissions baseline, at our cost
Start with a measurement, not a commitment.
We meter diesel use and emissions at up to three of your sites, at our cost. You keep the report whether or not you go further.
- Litres consumed and generator run hours, measured, not estimated
- What diesel really costs you per kilowatt-hour, fuel and maintenance separated
- Grid availability and outage pattern at each site
- Scope 1 emissions from your generators, in a form your auditors can work with
For institutions in Nigeria operating five or more generator-backed sites, or a single facility with 250 kVA or more of installed generation. We take on a limited number of baselines each quarter, prioritised by programme fit.
Diesel and Emissions Baseline

Get it measured at your sitesThe equipment
Specified the way a lender’s engineer would specify it.
We specify storage and solar only from manufacturers on BloombergNEF’s Tier 1 lists for their category. Supplier identities are shared with counterparties under confidentiality agreements.
Battery storage
Vertical modular LFP cabinets
Lithium iron phosphate in vertical, modular outdoor cabinets from BloombergNEF Tier 1 storage manufacturers. A small footprint for constrained sites, added cabinet by cabinet to match measured demand, with state-of-health warranties specified for the contract term.
Solar generation
Tier 1 bifacial PV
High-efficiency modules from BloombergNEF Tier 1 manufacturers, sized so that solar charges storage first. That priority decides how much diesel a site actually displaces.
Monitoring and control
Metered dispatch
Remote monitoring and solar-first control produce the site-level meter record behind every invoice and every emissions report.
The standard we specify
Certification, warranty and performance terms are fixed in the supply contract and verified at factory and site acceptance, before any equipment enters a financed programme.
- Storage safety
- IEC 62619 cells and modules; IEC 62477-1 power conversion; fire-propagation test data to UL 9540A or equivalent
- Solar modules
- IEC 61215 and IEC 61730
- Warranties
- State-of-health guarantees tested at operating depth of discharge, assignable to financing parties
- Acceptance
- Factory acceptance tests, then site acceptance against defined performance criteria
Sectors
Built for estates where the load never stops.
Programme and site detail is shared with counterparties under signed confidentiality agreements.
Telecommunications
Network facilities and data centres that carry continuous load, where diesel is one of the largest operating costs and downtime breaches service commitments.
Financial services
Branch networks, head offices and data centres, where a distributed generator fleet is the hardest line to defend in a climate disclosure.
Healthcare, manufacturing and commercial estates
Sites where an outage costs more than the fuel, and where capital is better spent on the core business.
For lenders and partners
Structured to be financed.
Every cost line in a Mansa Energy model carries a status as well as a number, so lenders and manufacturers see which figures are modelled, which are quoted and which are contracted.
- Stage 1
Indicative
A modelled assumption, disclosed as one, used to size a programme before suppliers are engaged.
- Stage 2
Quoted
A supplier's offered price replaces the assumption before financial close.
- Stage 3
Contracted
Secured in an executed agreement, with warranty and performance obligations sized to the debt term.
Lenders and investors
An asset built for diligence
- Programmes designed to sit in ring-fenced project companies, with security over contracted cash flows
- Senior debt structures that accommodate commercial and development lenders together
- Debt service tested against a combined downside case
- Step-in rights, direct agreements and assignable warranties required in equipment contracts
- Holding structure designed for institutional investors from the start
Manufacturers, EPC and O&M partners
A programmatic channel
- One counterparty aggregating demand across institutional estates
- Payments against documents and milestones, under letters of credit and on-demand guarantees
- Defined specifications, interfaces and acceptance tests
- Non-circumvention that protects clients, suppliers and financiers alike
- Repeat orders as programmes extend to new sites and sectors
Government and public bodies
Energy as a metered service
- No upfront capital from the public body
- Measured emissions reductions that support national transition targets
- Performance and availability risk held by the provider
- Contract structures adaptable to public procurement rules
Programme information, financial models and supplier terms are shared with qualified counterparties under a mutual confidentiality agreement.
Request a programme briefingGovernance and assurance
Independent review is built in, not bolted on.
Every programme is prepared to the evidentiary standard that development lenders, auditors and credit committees apply, from the first site survey to the last report.
Engineering
Independent technical review
Before financial close, system design, supplier documentation and acceptance testing are reviewed by an independent COREN-registered engineer.
Legal
Counsel on every contract
Every supply, service and financing agreement is reviewed by Nigerian energy and finance counsel before execution, with international counsel where the financing requires it.
Confidentiality
Agreements before data
Mutual confidentiality agreements before any site data, model or supplier term changes hands. Client identities are never shared without consent.
Integrity
Counterparty screening
Know-your-counterparty and sanctions screening required of every supplier, contractor and financing party, with anti-corruption undertakings written into our contracts.
Environment and social
Lender-aligned standards
Programmes designed to the IFC Performance Standards, with an environmental and social management system in place before first financial close and battery end-of-life planned from the design stage.
Data
One meter record
Invoices, performance reports and emissions figures all drawn from the same site meter data, so every number can be traced to its source.
Advisers and counsel are identified to counterparties during diligence, under confidentiality.
Leadership
Founder-led, with financeability as the first design test.
Segun Adedeji
Founder and Chief Executive Officer, Mansa Energy. Group Chief Executive, Kaarakata Group.
Segun founded Mansa Energy on the view that diesel dependency in Nigeria is a financing and structuring problem more than a technology one. He leads the company’s work with global storage and solar manufacturers, institutional offtakers and capital providers, and holds every technical and commercial term to one test: it must survive independent engineering review and credit committee scrutiny.
He has led Kaarakata Group since founding it in 2010, building a group active across 14 countries. A computer science graduate of the Federal University of Technology, Akure, he began his career in infrastructure engineering with the EPC contractor on Ondo State’s SITADEC programme, commissioning earth-station, wireless and data-centre systems, before advising the State Governor’s Office on its network infrastructure through to handover.
White paper
Scope 1 Has a Start Date
IFRS S2 and the Nigerian generator estate
For reporting periods from 1 January 2028, a public interest entity’s generator estate enters its IFRS S2 Scope 1 disclosure. Energy decisions taken before then set what boards disclose for the decade after. The paper sets out what changes, when, and what a compliance-grade energy programme has to deliver.
