13th March 2025The UK’s renewable energy landscape has undergone a dramatic shift over the past decade.
While the sector was once driven by government subsidies like Renewables Obligation Certificates (ROCs), it’s now defined by innovation, market-driven incentives and the urgent need for Grid flexibility. For landowners, this changing dynamic presents new opportunities to diversify the income streams from their land, all without relying on traditional subsidy schemes.
It’s also worth discussing advancements in battery storage, Contracts for Difference (CfD) auctions and decentralised energy generation. These developments give landowners with the right sites the opportunity to tap into profitable energy markets in 2025 and beyond.
Whether this is through co-locating battery storage with landfill gas projects, solar or wind farms, leasing land for energy projects or investing in short-term operating reserve (STOR) solutions, there are numerous ways to diversify your income streams while supporting the UK’s transition to a low-carbon future.
In this blog, I’ll explore the most promising opportunities available to landowners in 2025. By explaining how the sector currently operates, I’ll offer insights into how landowners can maximise their assets, navigate current Grid constraints and secure long-term financial returns in a subsidy-free energy market.
Unlocking Value With Battery Storage
Battery storage is rapidly emerging as a crucial technology for balancing renewable energy generation and ensuring Grid stability.
As wind and solar output naturally fluctuate, large-scale battery storage is becoming an essential solution for storing excess power and supplying it when demand is higher. This has been referred to as ‘enhanced frequency response services’.
Battery Storage and Solar Energy
The first UK solar farm built without subsidies (Anesco’s 10 MW project in Bedfordshire) was commissioned in 2017 alongside a 6 megawatt (MW) battery storage unit. Since then, battery storage has continued to prove its value, making solar-plus-storage projects more financially viable.To give you more context on this topic, I’ll quickly outline exactly why battery storage is so valuable for helping landowners diversify their existing income streams.
Maximising revenue by selling stored energy at peak prices
One of the biggest advantages of battery storage is the ability to store electricity when production is high and demand is low. By doing this, you’ll be able to sell energy when prices increase.
Traditional energy sources are at the mercy of fluctuating generation, consumption patterns and global markets. However, battery storage allows operators to strategically time their energy sales to secure maximum income.
By discharging stored energy at critical times, landowners and developers can secure higher returns compared to selling power as it’s generated.
Reducing dependence on Grid availability for export
Grid congestion remains one of the biggest challenges for renewable energy projects.
Battery storage reduces reliance on immediate Grid export by allowing energy to be stored and released when Grid conditions are more favourable. As I mentioned above, this means that landowners with renewable energy installations can avoid curtailment issues and instead store excess power for future use or sale.
This flexibility not only improves financial viability but also enhances the overall resilience and efficiency of local energy networks.
Unlocking new revenue streams through Grid-balancing services
Battery storage doesn’t just benefit individual energy producers – it also plays a crucial role in stabilising the National Grid.
The UK’s electricity system requires constant balancing between supply and demand. For this reason, battery storage units are well-suited for providing rapid response services that help maintain Grid stability.
By participating in capacity reserve schemes, battery owners can earn additional income for helping National Grid manage fluctuations in electricity supply.
This makes battery storage a multi-revenue investment, offering financial returns not only from energy sales but from specialised Grid-balancing contracts as well.
Battery Storage and Wind Energy
Several wind farm operators are now integrating co-located battery storage to optimise energy output.
A great example of this is Vattenfall’s Pen y Cymoedd Wind Farm in South Wales. Vattenfall added a 22 MW battery system to improve Grid stability and helped to hugely enhance the wind farm’s profitability. While it cost £381 million to implement, it’s set to be well worth its initial cash injection.
Like with solar farms, battery storage enhances wind farm profitability by:
- Allowing operators to store power during low-demand periods and sell at premium rates
- Supporting the UK’s transition to decentralised energy markets, where flexibility services are highly valued
- Reducing curtailment, ensuring more clean energy reaches the Grid
So overall, the impact on wind income is relatively similar to what you’d see from solar projects.
Gas-Powered Grid Balancing Solutions
Battery storage is not the only option for landowners looking to enter the energy market.
Short-Term Operating Reserve (STOR) generators, traditionally diesel-powered but increasingly gas-based, provide another revenue stream.
Sites with Grid access and proximity to the gas network are in high demand for STOR projects, as they can quickly supply power to the Grid during peak times.
Site location leverage
Limited electrical Grid capacity remains one of the biggest obstacles to new energy developments around the country.
Landowners with sites that meet developer requirements hold a strong negotiating position, as Grid access is in high demand. Developers actively seek locations with available capacity, making well-situated land a valuable asset to them.
Landfill owners and operators possibly stand to benefit the most from this lay of the land. Many landfill sites already generate renewable energy from landfill gas, but as gas supplies decline, they often have excess Grid capacity.
This unused capacity creates an opportunity to repurpose the site for battery storage, solar or other Grid-balancing technologies.
The project operator would just need to seek the network operator’s approval to use this spare capacity – it isn’t an automatic right. This is because the new project might have a different impact on the electricity network.
For example, let’s say your landfill gas project is only using 700 kilowatts (KW) out of the available 1,000 KW Grid connection capacity. The project operator would need to get National Grid’s permission to use the remaining 300 KW of capacity for battery storage.
Choosing the Best Option for Your Land
Not every type of renewable energy technology suits every site, as the type of land required for different projects varies.
I always recommend that landowners assess the option that aligns with their land’s characteristics, Grid access and long-term business goals before taking on any project. A tailored approach ensures the best financial return and avoids costly missteps that can come with poor research.
For solar and wind projects, the key factor is export capacity (or how much electricity the site can send to the Grid). Battery storage requires both import and export capacity, as it charges and discharges energy.
Meanwhile, STOR backup generators (such as gas or diesel units) only need export capacity to function effectively.
Understanding these requirements helps landowners make informed decisions and ensures their energy projects remain viable in a rapidly evolving market.
The Role of CfD in 2025
While subsidies for new onshore wind and solar have ended, the UK Contracts for Difference (CfD) scheme remains in place for supporting renewable energy investments.
How CfD works for landowners
CfD contracts guarantee a fixed ‘strike price’ for renewable energy generators, ensuring income stability despite market fluctuations.
In 2025, the scheme has evolved to:
- Include battery storage projects in certain auctions
- Support co-located renewables (wind, solar and storage)
- Expand eligibility for smaller-scale, independent projects
For landowners, partnering with a developer in a CfD-backed project provides long-term financial security without reliance on direct subsidies. While I don’t feel that the CfD scheme is as valuable as the previous ROC scheme, it still offers net benefits to landowners and developers looking for security.
The Future of Renewable Energy Payments
With ROCs ending and CfDs taking over, landowners could face big shifts in income and opportunity.

Ready to Explore Your Options?
If you’re considering these opportunities, start by discussing them with your developer to assess their viability for your site. Even if they haven’t explored the ways in which landowners could diversify their income streams, they may be open to partnering with a specialist developer to unlock new potential.
It’s also worth consulting your solicitor to review your lease agreement. If you have the flexibility to pursue these projects independently, your land agent can connect you with experienced developers who can outline how your site could benefit.
Looking ahead, you should also factor in Grid connection rights when negotiating new renewable energy contracts or renewing existing ones. Securing control over the Grid connection at the end of a project can hold significant long-term value, ensuring future opportunities remain within your reach.
Final Thoughts on How Landowners Can Diversify Their Income Streams, and Looking to the Future
The UK’s renewable energy landscape is evolving rapidly, creating new opportunities for landowners to generate income without relying on subsidies.
From battery storage and flexible Grid services to CfD schemes and strategic site leasing, there are multiple ways to unlock the value of your land. With the right approach, landowners can secure long-term, stable income streams while contributing to the UK’s low-carbon future.
