Starting a Wind Farm for Investors and Developers: Top Tips

Are you curious about what goes into starting a wind farm for investors and developers? Join us as I walk through the key elements you should consider before diving in.

The development of wind farms plays a crucial role in the UK’s transition to renewable energy. For starters, wind farms provide an opportunity to generate sustainable, low-carbon electricity.

However, they’re also great contributors to economic growth and energy security. These projects offer landowners, site operators, developers and investors an excellent opportunity for generating stable, long-term returns. In an often volatile global market, this can be incredibly rewarding.

The growth of wind energy in the UK speaks for itself. In 2024, wind energy accounted for 30 per cent of the country’s renewable energy mix, up from 29.4 per cent in 2023. This is a significant jump from just 2.7 per cent in 2010, illustrating remarkable progress over the last decade.

In this article, I’ll explore the key aspects of wind farm development. I’ll start with the economic incentives that make them an appealing investment. But I’ll also discuss the technical considerations developers must navigate when selecting land. This includes securing financing and managing grid connection.

Is Starting a Wind Farm for Investors and Developers Worth It?

If you’re uncertain about the viability of wind farms, let’s look at why they’re generally considered an excellent investment.

Predictable and profitable returns for developers

For developers, government-backed schemes like the Contracts for Difference (CfD) play a significant role in ensuring predictable and profitable returns over the long-term.

These schemes aren’t as financially rewarding as the previous Renewables Obligation Certificates (ROC) scheme. But they still guarantee a fixed price for the electricity generated, effectively reducing market risks.

In the latest CfD Allocation Round 6 (AR6), announced on 3 September 2024, a record-breaking 131 projects were awarded contracts. These figures demonstrate the government’s commitment to supporting new renewable energy projects.

Consistent returns for investors over decades

For investors, wind farms offer the opportunity to achieve consistent returns over 20 to 40 years through the sale of electricity.

It’s important to note that upfront costs (from the planning stage to turbine installation) are substantial. Developers may also face challenges such as planning delays and Grid connection issues that can make wind farms less appealing.

However, despite these potential hurdles, technological advancements in turbine efficiency and economies of scale have made wind energy seriously cost-competitive. This has piqued the interest of institutional investors. These include pension funds and private equity firms seeking stable, long-term returns in an often volatile global market.

The Land Required for a Wind Farm and What Developers Should Look For

Selecting the right land is a critical step in the success of any wind farm project. Typically, developers require between 25 and 40 acres per turbine, depending on the project’s design and turbine size.

Determine average wind speeds

If you’re a developer seeking potential sites, one of the most important considerations is wind speed. Sites with average wind speeds of 6 to 8 metres per second (m/s) are ideal, although slightly lower speeds may still be viable at certain locations.

Developers often conduct wind resource assessments using anemometers and historical wind data to assess a site’s suitability. So, be prepared to carry out these tests before approaching a landowner and/or to negotiate an early option agreement to secure the land while such assessments are being carried out.

Consider topography and proximity to infrastructure

Topography also plays a key role. Flat or gently sloping land minimises construction challenges and reduces costs.

Proximity to existing infrastructure, such as roads and electricity grid connections, can further lower costs associated with site preparation and transportation of turbine components.

Avoid protected areas

Environmental considerations are crucial. Developers should beware of protected areas, such as sites of special scientific interest (SSSIs), which could lead to objections during the planning process.

Securing Access to the Land With Option Agreements

Securing access to land is a critical component of any wind farm project’s development.

Developers typically use option agreements to handle this part of the process. These agreements provide them with the right to lease or purchase the land once an agreed condition is met – for example, if planning permission is granted.

These agreements offer financial benefits to landowners in the form of a lump sum. But they also allow developers to secure land without making immediate, substantial financial commitments.

Generally, the key elements of an option agreement include:

• An exclusivity period: Ensures that no other developers can negotiate with the landowner and/or utilise the land in question, unless the Option Agreement expires. The land is essentially reserved during the option period.

• Pre-agreed lease terms: These define rental payments, revenue-sharing arrangements and the responsibilities of both parties, helping to avoid disputes.

• Termination clauses: Outline the conditions under which the agreement can be terminated and the rights and obligations of each party if this occurs.

Lumify SiteStart™ provides landowners and developers with the tools to negotiate from a position of strength. So, you can ensure that every aspect of your project – from site selection to commercial terms and stakeholder agreements – is optimised for success.

How Developers Can Access Capital for a Wind Farm and How Investors Are Involved

Wind farm projects require significant upfront capital, which is often raised through a combination of funding sources.

Traditional bank loans are one option, with major financial institutions such as Barclays and HSBC offering green financing specifically for renewable energy projects. In addition to loans, developers may opt for equity financing, where they partner with investors in exchange for a share of future revenues.

For example, the Beatrice Offshore Wind Farm in Scotland was funded through a partnership between SSE Renewables, Copenhagen Infrastructure Partners and Red Rock Renewables. This enabled the project to share risks while accessing substantial capital.

Another option is the issuance of green bonds, which allow developers to raise funds specifically for environmentally sustainable projects.

Additionally, government subsidies such as the Contracts for Difference (CfD) scheme provide financial stability, offering developers a guaranteed price for electricity generated, further enhancing the appeal of wind farms to investors.

How Developers Can Set Up Grid Connection

Setting up a Grid connection is a crucial step for wind farm developers.

The process typically begins with an application to the local Distribution Network Operator (DNO) or National Grid. The developer must then assess the costs of connecting to the nearest substation, which can vary depending on the distance and capacity required.

Developers also need to secure connection agreements, which outline the terms of the connection, including capacity and timelines.

One of the major challenges facing developers is Grid congestion, which can delay projects. However, collaborations between developers and Grid operators can help mitigate these risks and it may be possible for developers to fast track their Grid application if they can demonstrate that their project has progressed to a more advanced stage than other developers who are currently ahead of them in the Grid connection queue.

Drawing Up an Appropriate Lease

A well-drafted lease agreement is essential to ensuring a smooth relationship between developers and landowners throughout the lifecycle of the wind farm.

Typical lease terms for wind farm projects range from 20 to 40 years, which is in line with the operational lifespan of average wind turbines. These agreements may include provisions for extending the lease if necessary, but this isn’t always the case for initial leases.

Outline decommissioning responsibilities

In addition to setting clear rent and revenue-sharing terms, developers must address decommissioning responsibilities, ensuring that the land is restored after the project concludes.

Add clauses to future-proof the lease

To future-proof the lease, clauses that allow for turbine upgrades or the addition of new turbines (or other types of ancillary equipment such as battery storage) can be included. However, developers will need to convince the landowner and local planning authority to go ahead with this first.

Consider repowering the project

If a wind farm is still functional and has life left in it at the end of the initial lease period, developers and investors may want to repower the project. This process is generally easier to do than starting a new wind farm from scratch and lets the project continue making income while benefiting from technological advances in the sector.

What Happens During the Wind Turbine Construction Period?

The construction period of a wind farm involves multiple stages that each require careful coordination.

Developers must begin with site preparation, which includes clearing the land and building access roads.

The next major step is turbine delivery, where large components, such as turbine blades and towers, are transported to the site, often requiring specialised vehicles and logistics planning.

The final stage involves the actual installation of the turbines, where the turbines are erected, blades are attached and connections to the Grid are made. This phase presents several challenges, such as coordinating the transportation of large components to remote or difficult-to-reach locations.

For instance, the Stronelairg Wind Farm in the Scottish Highlands required significant coordination to transport turbine parts across rugged terrain, highlighting the logistical complexities involved in wind farm construction.

Developers should leave plenty of time for this process, as they can face unexpected delays with anything from access roads to supply chain issues.

How Developers Should Manage and Monitor a Wind Farm

Once construction is complete, developers must focus on maintaining the wind farm’s operational efficiency.

Monitoring systems, such as Supervisory Control and Data Acquisition (SCADA) systems, are used to track the performance of turbines in real time, ensuring any issues are quickly identified and addressed.

Regular maintenance is also essential, and developers should work closely with site operators to schedule inspections and repairs. This minimises downtime and maximises energy production.

Developers should also engage with local communities to maintain positive relationships. By doing this, they can also address any concerns and build long-term support for the wind farm. This community engagement ensures that wind farms continue to be seen as a positive force, encouraging further development of renewable energy projects.

Speaking with the local communities throughout the lifecycle of a project can also be useful for building other potential projects around the vicinity.

In short, it’s a win win.

What ROC Removals Mean for Developers and How This Could Affect Their Finances

The ROC scheme was phased out for new projects in 2017. It was replaced by the CfD scheme, which is generally seen as less financially rewarding for developers and investors.

This shift has impacted developers by changing the revenue model for new wind farm projects. In the future, I expect that more developers will rely on CfD auctions or private Power Purchase Agreements (PPAs) to secure stable, long-term revenues.

The move to the CfD scheme has increased competition, as developers now compete for a limited number of contracts. To adapt, developers must focus on cost optimisation and explore alternative revenue streams. Projects like the Viking Wind Farm in Shetland have entered into PPAs. By selling excess power directly to corporations, they’re further diversifying their income streams.

By entering into PPAs, project developers can lock in long-term pricing for the electricity generated, ensuring steady revenue. This long-term financial security makes it more attractive to investors and banks. In turn, this helps secure the funding required for construction and operation.

The removal of ROCs certainly presents challenges. But the ongoing support for wind energy through the CfD scheme ensures that wind farm development remains financially viable.

What About Those Who Want to Invest in Green Energy on a Smaller Scale?

Investing in wind farms is becoming an increasingly accessible option for individuals with limited funds.

While large-scale wind farm investments typically require significant capital and active participation from developers, there are now ways to get involved in wind energy without having to directly fund construction or operation.

One route is through green indexes and sustainable investment funds. These options focus on companies and projects committed to environmental responsibility, giving those with less funds the chance to invest in small sections of the industry.

Green indexes (like the S&P Global Clean Transition Index or the MSCI ACWI Low Carbon Leaders Index) track the performance of companies engaged in renewable energy. These indexes often include wind energy producers.

By investing in these funds or index-tracking exchange-traded funds (ETFs), individuals can gain exposure to the growth of the wind energy sector without having to select and manage individual stocks or projects. As tracking individual stocks can be highly complex, it’s a lower-risk option for inexperienced investors.

These funds typically include a diverse range of companies, from turbine manufacturers to large energy utilities with significant wind portfolios. So, it’s a potentially low-risk and passive way to invest in the clean energy revolution.
