Finance & Ownership Models
Energy-as-a-Service, Modeled Both Ways
Turn any energy project into a third-party-financed deal. CogenS™ models EaaS from both the building-owner and the provider perspectives, with four deal structures and a dual-MARR solve that balances each party’s target return.
Why EaaS
Keep the Capital Off the Balance Sheet.
Many commercial and industrial hosts want the energy savings without owning the equipment. Energy-as-a-Service delivers exactly that: a provider funds, owns, and operates the assets, and the host pays for the service. The deal only works if it clears the provider’s return hurdle and lowers the host’s cost of energy — and the contract structure decides how that value is split.
CogenS™ runs one project-finance model behind every structure, so you can compare ownership vs EaaS, and concession vs tolling vs shared-savings vs PPA, on the same physical dispatch — and hand each counterparty a report that speaks to its own perspective.
Deal Structures
Four Ways to Structure the Deal
The right structure depends on whether the asset stores energy or generates it. Behind-the-meter storage uses concession, tolling, or shared-savings; on-site generation uses a PPA.
Energy Concession
AvailableStorage / DERThe provider takes over the utility account and pays the DER-reduced bill. The host pays a managed rate on its own consumption — energy $/kWh, optionally plus demand $/kW-month — as if paying the utility, plus a service fee that recovers the provider's capital and margin. The host's net savings is the full baseline 100%-grid bill it no longer pays, minus the managed fee. Lowest risk for the host.
Capacity Tolling
AvailableStorage / DERThe host pays a capacity charge ($/kW-month on the asset's rated power) plus a throughput charge ($/kWh on energy delivered), and keeps its utility account. Its net benefit is the DER bill reduction minus the toll. A balanced structure for demand-driven and high-utilization loads.
Shared-Savings ESA
AvailableStorage / DERThe host pays the provider a share of the measured savings pool — the electricity-bill reduction (the M&V base) plus, optionally, avoided carbon cost, resilience/backup-genset value, and avoided grid-upgrade O&M. Incentives align: no savings, no fee. The host keeps its utility account and the remaining savings.
On-Site PPA
AvailableOn-site generation (CHP)For on-site generation, the host buys the electricity (and, for CHP, the useful thermal output) the asset generates at a contracted $/kWh (or $/MMBtu) below grid, and keeps its utility account. Modeled in the CHP module, including waste-heat capture revenue. Simplest, most predictable terms.
The Financial Model
Built for the Investment Decision
Two Parties, One Model
Every EaaS project is computed from both the building-owner (cost-of-ownership) and the provider (revenue) perspectives, from the same physical dispatch — plus the utility bill and who carries it.
The Fee Is Solved, Not Guessed
Enter a target provider IRR and CogenS™ solves the managed rate, capacity/throughput charge, or savings share that hits it exactly — root-found through the same income statement the report shows.
Dual-MARR Balance
Enter a building-owner return target too, and the solver balances both parties — finding the terms that bring the provider IRR and the owner IRR to the same fraction of their respective targets.
A Full Project-Finance Engine
Income statement, depreciation and taxes, after-tax cash flow, incentive stacking, and KPIs — NPV, IRR, simple and discounted payback, benefit-cost ratio, and equivalent annual revenue — in 75+ currencies.
Three Perspectives
Every Deal, from Every Angle
One dispatch, three financial views — so both sides of the table see the numbers that matter to them.
EaaS Provider
A full income statement: fee revenue → operating costs → EBITDA → depreciation → taxes → net income, with NPV, IRR, payback, benefit-cost ratio, and equivalent annual revenue. In a concession, the provider carries the host's grid bill as an itemized expense.
Building Owner
What the host keeps after the fee: net benefit, NPV, IRR, and payback — with no capital on its balance sheet. The benefit basis depends on the structure (full bill avoided, DER savings, or a residual share).
Utility Bill
The grid bill the dispatch produces — energy, demand, fixed, and export credit — and who pays it: the provider (concession) or the host (tolling, shared savings, PPA).
