Power Purchase Agreements

Reduce energy costs without funding the system upfront.

An onsite PPA can allow your business to purchase electricity generated from a solar and optional storage system at an agreed price per kWh while the project provider funds, builds, operates and maintains the infrastructure.

Power Purchase Agreement commercial energy model
Why businesses consider a PPA

Shift the project from capital purchase to energy contract.

No upfront CapEx

Preserve capital and debt headroom while treating energy payments as an operating cost.

Price visibility

Compare an agreed PPA energy rate against the relevant components of your grid electricity cost.

Performance responsibility

The project provider carries agreed construction, maintenance and performance obligations.

Renewable energy outcomes

Increase the use of renewable electricity and structure environmental certificate treatment to suit the contract.

Storage option

Long-duration VRFB storage can be assessed where the site benefits from shifting solar energy across several hours.

End-of-term flexibility

Commercial structures may include extension, purchase or removal options depending on the final contract.

How an onsite PPA works

From load data to a bankable commercial offer.

01

Feasibility & data

Review interval data, recent bills, site constraints and connection requirements.

02

Commercial offer

Develop indicative kWh pricing, term, escalation structure and buyout options.

03

Design & approvals

Progress engineering, grid compliance, safety and contractual requirements.

04

Build & operate

Fund, construct, commission, monitor and maintain the operating system.

05

Meter & settle

You purchase metered onsite energy while the grid continues to support the site as required.

06

Review performance

Use transparent reporting to track generation, storage and commercial outcomes.

Commercial solar and battery project
Is a PPA worth assessing?

It becomes more interesting when the site has meaningful and predictable electricity demand.

High annual electricity spend
Consistent weekday or daytime load
Suitable roof or land
Longer-term site occupancy
Access to interval data
Interest in reducing capital outlay

These are screening indicators only. The economics depend on tariff structure, site constraints, load shape, project size, financing and contract terms.

Frequently asked questions

Common PPA questions.

Who maintains the system?

Under a typical PPA structure, the project provider remains responsible for agreed operations and maintenance.

Can the business buy the system later?

Buyout options can be built into the contract at agreed points, subject to the final commercial structure.

What happens if generation is lower than expected?

Performance obligations, exclusions and remedies are defined contractually. These need to be reviewed carefully before execution.

Decision guide

Compare a PPA with customer ownership.

Review how capital, energy pricing, maintenance, performance risk and contract flexibility differ before choosing a structure.

Next step

Compare a PPA against your current electricity position.

Bring a recent bill or interval data and we can start with an indicative feasibility discussion.
