Farmers and landowners could be well placed to tap into the benefits of decentralised energy systems as the cost of the equipment falls, experts have said.
Those with high onsite energy use have the potential to be at the forefront of the battery technology revolution with solar being the most complementary technology for battery storage.
The opportunities available on-farm recently led NFU Scotland to host a special event offering expert advice on installation and funding as part of its Renewables Development Initiative (RDI) in Coupar Angus.
Thomas McMcMillan,of Savills Smiths Gore, who co-ordinated the event, says: “We are on the cusp of them being commercially viable.
“There is an appetite for it among farmers but it is a matter of getting the timing right.”
Mr McMillan says the cost of the kit has reduced by about 50 per cent in the last three years ‘and the advancement in the technology is substantial’.
It came as a new report published by KPMG and the Renewable Energy Association (REA) last week said the reduction in costs meant storage could become economically viable.
The report highlighted recent technology innovation and production enhancements which meant the cost of solar power and wind power were falling rapidly.
“The greatest cost reduction has been experienced by solar, and some forms of energy storage are expected to follow a similar cost reduction path,” the report says.
“With tools for customers to manage their energy use, decentralised energy systems could help lower energy costs for consumers, and contribute to decarbonisation and security of supply objectives.”
REA chief executive Dr Nina Skorupska says: “This year is going to be the breakthrough year for energy storage and the growth of decentralised energy. The industry must draw a line under the turbulence of the past year and look to the future.
“This report shows storage is already upon us and the cost of renewable technologies are coming down and many companies are looking forward to the post-subsidy business model.”
The report states the continued growth of decentralised energy solutions could transform the British energy industry from a national energy market administered by Government, regulator and utilities, to one where local integrated energy solutions are determined by consumers, businesses and communities.
“This is already underway, fuelled by the rapid penetration of distributed solar PV,” the report adds.
“A further boost to decentralised energy markets could occur if storage installations become more economic and can be effectively integrated into the energy system.”
The REA is now calling on the UK Government to remove regulatory barriers and introduce an energy storage definition in the current energy bill.
Opportunities for deployment
Benefits – Increased deployment of decentralised energy and storage offers important benefits to the national energy sector, including:
Lower overall energy costs as the risk of potentially high peak energy prices is reduced
New generation and network investment for peak capacity is not required
Reducing the risk of negative prices at times of low demand, when the energy system is dominated by ‘must run’ nuclear and renewables
Consumer or local energy management helps balance local demand and supply, thereby contributing to security of supply
Reduced UK dependence on imported fossil fuels, at a time when North Sea oil and gas production is declining (a trend that may accelerate give current low prices)
An increased contribution to decarbonisation by enabling greater penetration of variable renewable generation within the energy system
