Buy the electricity, not the equipment.
Power purchase agreements: IRIS-financed energy projects
Under a power purchase agreement (PPA), IRIS develops, finances, owns and operates the system on your site, and your business buys the electricity it produces under a long-term contract. Your capital stays in your core business. Also described as Energy-as-a-Service or an independent power producer (IPP) arrangement.
Who this is for
A clear fit.
Finance leaders who want a contracted energy cost without a capital project, and operators who would rather not carry the technology and performance risk.
Typical applications
- On-site solar supplied under a long-term tariff
- Solar plus battery storage under one energy contract
- Hybrid generation for sites with constrained grid capacity
- Multi-site portfolios contracted as one arrangement
What IRIS delivers
Scope, ownership and commercial terms.
Delivery scope
- Feasibility and load assessment
- Project development, permitting and financing
- Engineering, procurement and construction
- Ownership of the asset for the contract term
- Operation, maintenance and performance monitoring
- Agreed end-of-term options
Who owns and operates
- Ownership
- IRIS owns the system for the contract term.
- Operation
- IRIS operates and maintains it; your business purchases the electricity.
Commercial considerations
Terms depend on the project assessment: your load, the site, the system configuration and the contract duration. Typical points agreed include the tariff and how it changes over time, minimum offtake, contract length, and what happens at the end of the term.

Common questions
What clients ask first.
How does a PPA differ from owning the system?
With ownership you invest up front and keep the full generation benefit. Under a PPA IRIS invests, owns and operates the system, and you pay for the electricity it produces at an agreed rate. The choice usually comes down to capital priorities and how much operating responsibility you want to hold.
What determines whether my facility is suitable?
Sufficient daytime load, usable roof or land, a stable grid connection, and a contract term long enough to finance the asset. An initial assessment answers this quickly.
Who is responsible for maintenance and performance?
IRIS, for the life of the contract. Performance is monitored continuously and maintained against the agreed terms.
