On-site Electricity Generation
A practical route to market for developers, asset owners, and large energy users looking to generate, optimise, and monetise power at source.
Introduction
On-site generation has moved well beyond a sustainability statement. For developers, industrials, and large energy users, on-site electricity generation is now assessed on commercial terms. Output must be optimised, revenue must be defensible, and performance must hold up under lender and investor scrutiny.
That creates a more demanding operating environment. Generating power on site is one challenge. Knowing when to consume it, when to export it, and how to extract maximum value from every unit requires a different level of expertise entirely.
Captured Carbon supports on-site generation assets across trading, optimisation, PPA structuring, and regulatory compliance — helping turn on-site renewable energy generation capacity into a durable, financeable revenue stream.
Challenges for Developers and Energy Users
- Translating output into revenue
Generation capacity alone does not create value. Without a defined route to market, output is exposed to merchant risk and suboptimal pricing. Projects need structured trading and dispatch strategies to ensure on-site generation is sold at the right time and at the best available price.
- Managing export and self-consumption decisions
For co-located and C&I assets, the balance between self-consumption and export changes constantly. Poor dispatch decisions leave value on the table. Strong on-site renewable energy generation strategies require real-time visibility and disciplined execution.
- Regulatory and scheme complexity
Support schemes, grid codes, market registration, and compliance obligations all interact in ways that create risk for the unprepared. Developers who do not understand their obligations under schemes such as RESS, REFIT, or RHO face delays, penalties, and revenue leakage.
- Financing and bankability
Lenders require credible revenue forecasts backed by evidence of professional management. On-site generation projects without structured trading and optimisation frameworks increasingly face scrutiny over assumptions, performance risk, and downside scenarios.
How Captured Carbon Supports On-site Generation
Captured Carbon works with developers and large energy users as trading partners, optimisation advisors, and route-to-market specialists. The aim is consistent, bankable performance from on-site generation assets across their full lifecycle.
- 1. Trading and revenue optimisation
Power from on-site generation assets is traded actively into wholesale and balancing markets. Dispatch strategies do not passively accept prevailing prices; they respond to price signals, grid conditions and asset constraints.
- 2. PPA structuring and offtake
Where long-term revenue certainty is the priority, Captured Carbon structures and negotiates Power Purchase Agreements that are commercially competitive and financing-ready. Power purchase agreements are designed around asset economics, not just headline price.
- 3. Regulatory scheme advisory
Support scheme eligibility, application management, and ongoing compliance under RESS, REFIT, SRESS, and RHO are handled with direct experience of how these frameworks operate in practice. This reduces administrative burden and protects revenue entitlement.
Core Revenue Streams for On-site Generation
Wholesale and Balancing Markets
Active trading of exported on-site electricity generation into day-ahead and intraday markets captures price upside. Balancing market participation adds further value when conditions are favourable. Output is not left unsold at default prices.
Power Purchase Agreements
Fixed or indexed PPAs provide a stable floor of income that helps financing and reduces merchant risk exposure. Captured Carbon can support bilateral and aggregated PPA structures depending on project scale and appetite for risk.
Renewable Support Schemes`
RESS, REFIT, SRESS, and RHO make up a large part of the revenue for eligible on-site renewable energy generation projects. Captured Carbon helps with qualification, auction preparation, and scheme compliance to ensure that entitlements are secured and maintained.
Environmental Certificates
Guarantees of Origin and other renewable certificates add a secondary revenue layer. They are more relevant now for corporate off-takers with sustainability commitments and can enhance overall project economics.
Financial Modelling and Bankability Support
Captured Carbon builds financial models for on-site generation assets that reflect real-world revenue behaviour in live markets. This includes revenue stack assumptions, downside scenarios, sensitivity analysis, and dispatch logic to give lenders and investors a credible, not optimistic, picture.
Regulatory Compliance and Performance Reporting
Operational support extends beyond trading. This includes market registration, licensing, scheme compliance, settlement reconciliation, and performance reporting. The objective is to ensure forecast revenues from on-site electricity generation translate into cash received, with full visibility for investors and lenders throughout.
Forecasting and Dispatch Optimisation
On-site generation value is driven by accurate forecasting and timely execution. Captured Carbon applies price, volume, and constraint forecasts to position assets where value is highest, while respecting technical limits, grid obligations, and contractual commitments.
Industries We Support
Industries We Support
Solar PV developers
Utility-scale and distributed solar assets require active trading and PPA strategies. We support project developers from route-to-market design through to ongoing dispatch and compliance.
Wind developers
Wind assets face variability and curtailment risk. We support structuring revenues through wholesale markets, support schemes and PPAs to deliver stable and bankable returns.
Co-located renewable and storage projects
Generation assets and battery storage require integrated optimisation when co-located. We coordinate generation and dispatch decisions to reduce curtailment and capture combined value across both assets.
Large energy users and C&I
Industrial and commercial operators with on-site renewable energy generation must balance self-consumption with export economics. We support controlled market participation without compromising site reliability.

FAQs for On-site Generation Projects
A: It is the production of electricity or gas at or near the point of consumption, typically from renewable sources such as solar PV, wind, or biogas.
A: Through a combination of self-consumption savings, wholesale market trading, support scheme payments, PPAs, and environmental certificates.
A: Not entirely. Self-consumption reduces grid supply costs. But export, when properly traded, adds a direct revenue stream on top.
A: It is possible, but increasingly difficult. Lenders prefer revenue certainty. A well-structured PPA or scheme contract significantly improves financing terms.
A: The RESS, REFIT, and SRESS schemes cover most renewable technologies. Eligibility is determined by type of project, scale, and connection, and Captured Carbon will advise on the most appropriate route for each asset.
