Renewable energy helping farmers increase efficiency

Uncertainty brought about by Brexit and a pattern of lower farm incomes will challenge farmers to think carefully about energy use in 2017 and beyond. Olivia Midgley reports.

Increasing business efficiency and cutting costs will once again be key in 2017, as the UK farming industry anticipates falling incomes and the potential loss of income support in post-Brexit Britain.

 

While those contemplating investing large amounts of money in projects such as renewables may have put their plans on hold for the time being, experts believe there is still a good business case to make for introducing new technologies on-farm.

 

Richard Palmer, head of energy and estate business management at Butler Sherborn, says when it comes to energy, farmers will add most value to their businesses by focusing on how much energy they use, when they use it and where it comes from.

 

He says: “The UK energy system is constrained and the Government is incentivising customers to think differently through, for example, the introduction of a Capacity Market Levy and the roll-out of smart meters.”

 

Some farmers, depending on the classification of their energy use, will have to upgrade to smart meters by April 2017.

 

Mr Sherborn says: “These changes will increase meter operating costs and mean winter peak time costs between 4pm and 7pm will more than double compared with other periods in the same day.”


Management

As seasonal time of day tariffs become the norm, farmers will need to better manage their energy use if they are to avoid these peak rates, warns Mr Palmer.

 

However, they may also look to renewable energy and using batteries as part of their energy management strategy.

 

Joanne Ragdale, managing director at The Energy Manager, says: “In 2017, more than 60 per cent of your electricity bill will be made up of Government levies and taxes, distribution and network charges and supplier operating costs.

 

“Despite the drop in Government subsidies for renewable energy, generating energy on-site can still be economically worthwhile, even if only for short periods of time to avoid peak and indirect charges.”

 

Reassuringly, the Government is still committed to the decarbonisation of heat following its consultation on the Renewable Heat Incentive.

 

Three approaches stand out: electrifying heat with heat pumps; replacing methane with green gases, such as biomethane from anaerobic digestion plants; and developing heat networks or district heating schemes.

 

She adds: “Many farms generate income from rental properties, and with the minimum energy efficiency standards coming in on April 1, 2018, now is the time to benchmark, think strategically, and deliver innovation and efficiency gains through better energy management.”


Community energy opportunities

Community energy opportunities

While the renewables sector itself is no stranger to uncertainty, confusion and a lack of cohesion – which some would say has damaged investment and stunted growth – the industry has continued to grow.

 

According to a recent article in the London Economic, Britain ran coal-free for almost six days last quarter, the first time the country produced electricity without coal since 1881.

 

Scottish Renewables said Scotland was on track to meet at least 50 per cent of its energy needs from renewable sources by 2030.

 

And the Anaerobic Digestion and Bioresources Association confirmed there were 540 anaerobic digestion (AD) plants in operation across the UK producing biogas from a range of feedstocks including food waste and agricultural materials.

 

Helen Rumford, head of renewables at Thrings Solicitors, says: “There is an obvious partnership between AD and farms, particularly where there is a need for waste management.

 

“Farmers might want to consider investing in their own project or, if they do not have the upfront capital, then to lease their land to a developer and take a rent as well as a supply of heat and electricity, at a reduced cost, from the project.”

 

She also sees opportunities for community energy. With many of these projects facilitated on farmland, this is an area she is watching closely.

 

She says: “At the heart of community energy is a drive to tackle climate change, to make a positive difference to communities and, ultimately, to change the nature of energy ownership, generation and supply to a decentralised system. The aim is for renewable energy to be generated by local communities for local communities.

 

“There are a number of contributory factors to the continued success of community energy. With community groups being motivated by more than just monetary profit, they are arguably more likely to stay committed to projects in light of subsidy cuts, where perhaps some commercial developers might walk away.”

 

Iain Hibbert, an associate in the renewable energy team at law firm Roythornes, believes 2017 will also see a renaissance in solar energy.


What is battery storage?

Battery storage allows for excess electricity to be stored, so delaying exporting to times of peak demand, as well as balance the supply of electricity being exported during the day, to prevent power fluctuations.

 

There is, however, a shortage of sites suitable for connecting to the national grid and developers are racing to secure the best sites. Developers are encouraging landowners to instruct solicitors to act for them who have renewable experience and can act quickly.

Farmers earn profits from battery storage boom

Iain Hibbert, associate in the renewable energy team at law firm Roythornes, says he expects the surge in the battery storage market to continue in again strength this year, due to falling costs.

 

He says: “As the virtues of home batteries become clear and costs are continuing to fall, uptake in 2017 is set to rise. Advances in home battery technology and greater competition means we are likely to see home battery storage fall in price sufficiently to make it an economically viable option for many.”

 

Head of renewables at Thrings Solicitors Helen Rumford says her firm has been inundated with calls from landowners and developers considering standalone battery storage projects and also looking to incorporate energy storage into existing solar schemes.

 

She says: “Developers are racing to secure the best sites to install battery storage. We have seen a flurry of activity in the last 12 months.

 

“For farmers and landowners, there are some good deals to be had, but I would urge anyone thinking of going down this route to take professional advice from the outset.”

 

Ms Rumford says it is common for developers to sign several landowners up to an ‘exclusivity deal’, but then only proceed with just one or two projects.

 

She says: “My advice would be to look carefully at the terms on offer, but not to delay negotiations or be overly demanding, or they might move on to someone else.”

 

Dr Jonathan Scurlock, NFU renewables and climate change advisor, says he expects to see ‘hundreds or thousands of installations in a market with demand for thousands of megawatts’, although a full range of business models has yet to be developed and deployed as potential sources of income.


Small-scale 'behind the meter' energy storage options

Technological advancements have made ‘behind the meter’ energy storage viable on a smaller domestic or commercial scale.

 

‘Behind the meter’ simply means home-grown energy which is used on-site and does not involve a connection to the grid.

 

James Hoare, partner at LHW Partnership, says: “This allows farmers to bank excess energy produced by a renewable installation when they do not need it, and save it to use during peak times, such as evenings, in winter and during the grain drying period, when it can be costly to purchase.

 

“With the grid already saturated and the reduction in renewable energy subsidy payments, storage units are helping make renewable installations viable post-subsidy, thanks to the cost-saving potential.”

 

Farmers with a battery storage unit can make good savings on energy costs.

 

Mr Hoare says: “For example, excess energy generated from solar panels can be exported to the grid for a payment.

 

But farmers who choose to store their excess energy, rather than export it to the grid, will avoid a grid connection fee and make a great cost saving on energy bills.

 

“With falling storage prices, if you make a £20,000 investment, the payback period might be about eight years, after which you will be making a profit from your facility.”

 

He says the benefits of ‘behind the meter’ energy storage do not stop at cost savings. During a powercut or shortage from the mains supply, the battery can take over and provide essential power to the farm, all the while making it more sustainable.

 

Currently, the most common source of stored energy comes from solar PV panels, but battery storage can be used in conjunction with wind turbines, anaerobic digestion plants and hydroelectric installations.

 

Mark Newton, partner at Fisher German, says a separate method of producing electricity to store can be used.

 

This is known as short-term operating reserve and uses gas or diesel to operate an engine which produces electricity.

 

Mr Newton says: “Energy storage technology is developing so rapidly that within just a couple of years, we will be able to run everything from battery stored energy, including all our household appliances and cars.”
