Green Energy Contracts: How to Choose the Right One for Your Business
Consumers, investors and regulators are all demanding verifiable decarbonisation, making the switch to renewable energy a commercial necessity.
However, the green energy market is complex. Not all ‘green’ contracts are created equal and choosing the wrong one can lead to accusations of greenwashing or expose your business to long-term financial risk.
The Strategic Case for Green Power:
Why should your business move beyond a standard tariff and embrace a dedicated green energy contract?
- Cost Stability and Savings: Renewable energy technologies, particularly solar and wind, have seen significant cost reductions. Long-term contracts, such as Power Purchase Agreements (PPAs), allow businesses to lock in power prices for a decade or more, protecting against the volatility and political risk associated with fossil fuel markets.
- Reputational and Brand Enhancement: Certifiably green energy claims are a powerful marketing tool. They demonstrate a clear commitment to the environment, attracting eco-conscious customers and investors.
- Futureproofing: With global investment in the energy transition soaring and carbon regulations tightening, making the switch to renewable energy now helps businesses stay ahead of compliance curves and prepares them for an increasingly carbon-priced economy.
- Carbon Footprint Reduction: Green energy procurement is the primary lever for reducing a company’s Scope 2 emissions (Energy Indirect Emissions), directly supporting net-zero targets.
Understanding Your Green Options:
The level of positive environmental impact a contract delivers is defined by a concept known as additionality. Green energy contract additionality refers to an agreement that directly funds the construction of new renewable energy capacity that would not have been built otherwise. This differs from simply buying existing renewable energy and ensures the contract leads to a genuine increase in green power generation and verifiable emission reductions.
There are three primary types of contracts:
- Green Tariffs
A green tariff is the most common and simplest option. Your energy supplier commits to buying enough Renewable Energy Guarantees of Origin (REGOs) to match your consumption. While this allows a business to claim 100% renewable use, it offers low additionally because certificates are often bought from existing power plants, meaning your purchase does not fund new capacity.
Benefits: The easiest and most accessible first step, requiring zero upfront capital cost.
Considerations: The environmental claim is less robust for sustainability reports.
- Corporate Power Purchase Agreements (PPAs)
A PPA is a long-term contract to buy a specified amount of electricity directly from a named, often new, renewable energy project. These are used for showing commitment to funding new projects and provide the strongest credibility for sustainability leadership. PPAs also offer valuable long-term price certainty, often locking in costs for 10-20 years.
PPA Types: PPAs can be physical (on-site or off-site) with a direct power supply, or virtual (VPPA), a financial agreement used by large, multi-site corporations.
Considerations: PPAs involve complex legal structures, require a significant long-term commitment, and are typically suited for high-volume energy users.
- On-Site Generation
This involves installing and owning the generation asset yourself (e.g., rooftop solar) or using a financed PPA where a third party installs and maintains it on your property. This option offers maximum independence and control, allowing you to eliminate transmission charges and sell surplus energy back to the grid.
Considerations: This route is dependent on suitable site conditions, such as roof size and requires significant upfront costs if you choose to purchase the assets outright.

Green Energy Contracts: A Strategic Investment
Choosing a green energy is a strategic investment in future cost stability, investor confidence, and brand resilience.
For most small to medium enterprises (SMEs), a credible green tariff from a high-quality supplier is an accessible first step. For large corporations with robust ESG goals, the complexity and commitment of a corporate PPA are often necessary to demonstrate verifiable, high-additionality impact.
