Contracts for Difference Energy Explained (Cfd)

Contracts for Difference (CfDs) have emerged as a powerful tool in driving the transition to renewable energy by providing long-term revenue stability and incentivizing investment in low-carbon electricity generation. Administered by the Low Carbon Contracts Company (LCCC), the CfD scheme plays a pivotal role in supporting renewable projects and protecting consumers from volatile electricity prices. In this article, we will explore what a Contract for Difference is, how the scheme works, highlight examples of companies utilizing CfDs, and discuss the benefits of this mechanism in promoting renewable energy adoption.

What is a Contract for Difference (CfD)?

A Contract for Difference (CfD) is a private law contract between a low-carbon electricity generator and the LCCC, a government-owned company. The CfD scheme is designed to incentivize investment in renewable energy by providing generators with stable and predictable revenue streams. Under a CfD, the generator is paid the difference between the “strike price” and the market price for electricity.

How Does the CfD Scheme Work?

The CfD scheme operates through a competitive auction process, known as an “allocation round,” where eligible renewable projects bid for CfDs. During an allocation round, generators submit sealed bids indicating the strike price they require. The LCCC awards contracts to the lowest-priced bids until the allocated budget is exhausted.

The strike price represents the pre-agreed price that the generator will receive for each unit of electricity they produce. It provides long-term revenue stability for the generator, reducing the risk associated with renewable generation. The strike price is determined through a competitive auction process, ensuring cost-effectiveness and encouraging price reductions in renewable energy generation.

The reference price is the average market price for electricity, acting as a benchmark for comparison. If the market price for electricity falls below the reference price, the LCCC pays the generator the difference, bridging the gap and ensuring revenue stability. On the other hand, if the market price exceeds the reference price, the generator pays back the excess to the LCCC.

Who is eligible for a CfD?

The current CfD auction focuses on less established technologies, including offshore wind, tidal stream, wave, biomass with CHP, geothermal, and Advanced Conversion Technologies. A notable addition in this auction is the inclusion of onshore wind projects on remote islands.

In theory, all large-scale renewables in England, Scotland, and Wales can participate in CfD auctions if they meet the eligibility criteria. However, since 2015, the government has only conducted auctions for less established renewables. Established renewables such as onshore wind and solar have been excluded from competing in the CfD as the government has not held any auctions for these technologies in the last five years.

What happens after CfD contracts are awarded?

Once the auction results are announced, projects have the choice to proceed or not by making a Final Investment Decision. Successful projects must make this decision within 12 months from the auction or demonstrate that they have already spent 10% of the total project cost, known as the Milestone Delivery Date (MDD). From that point onward, the selected projects move forward by finalizing procurement and construction plans to meet their designated Delivery Year.

Examples of Companies Utilizing CfDs

1. Offshore Wind: Ørsted, a global leader in offshore wind development, has secured CfDs to support the construction and operation of large-scale offshore wind farms. These projects contribute significantly to the expansion of clean and renewable energy generation.
2. Onshore Wind and Solar: Companies like ScottishPower and Vattenfall have utilized CfDs to develop onshore wind farms and solar installations. By securing CfDs, these companies ensure stable revenue streams, which incentivize further investment in low-carbon electricity generation.

Why do investors find the CFd scheme more trustworthy?

The Contract for Difference (CfD) offers investors a predictable investment future by providing a fixed price for each megawatt-hour (MWh) of electricity they generate. In the volatile electricity markets, investors face inherent risks. The perceived riskiness of a project determines the overall cost of financing, with higher “cost of capital” associated with riskier ventures.

The cost of capital plays a significant role in determining the expenses of renewable projects, and consequently, the costs passed on to consumers. Since wind is an abundant and freely available resource, once a project is constructed, there are no ongoing fuel costs. The primary expenses for a wind farm revolve around repaying the borrowed funds used for its construction. This is where the CfD proves advantageous. By “stabilizing” a wind farm’s revenues through the CfD contract, investors gain certainty that their investments will be repaid in a predictable manner over a specific period. As a result, the associated project risks are reduced, allowing for a lower cost of capital to be secured. Ultimately, this leads to more affordable electricity prices for consumers.

Benefits and Impacts

1. Incentivizing Investment in Renewable Energy: CfDs play a crucial role in incentivizing investment in renewable energy projects by providing long-term revenue certainty. This stability attracts developers and reduces the financial risk associated with renewable generation, stimulating further investment in low-carbon electricity generation.
2. Consumer Protection and Cost Reduction: The CfD scheme protects consumers from paying increased support costs when electricity prices are high. By stabilizing revenue streams for renewable generators, CfDs contribute to reducing the overall cost of low-carbon electricity generation. This, in turn, supports energy affordability for consumers.
3. Renewable Energy Deployment: The CfD scheme facilitates the deployment of renewable energy projects, such as wind farms and solar installations. By providing long-term revenue stability and incentivizing investment, CfDs accelerate the transition to a low-carbon energy system, contributing to the UK’s renewable energy deployment targets and the achievement of net-zero emissions by 2050.
