1 Battery Storage: an agricultural update Energy Now Expo, Telford: 8 Feb 2018 Fendt e100 Vario electric tractor V2G ready Cleator, Cumbria 10 MW utility-scale Dr Jonathan Scurlock: Chief Adviser, Renewable Energy and Climate Change, National Farmers Union of England and Wales

2 The Revolution has already started New technological applications such as energy storage and vehicle-to-grid can enhance renewable selfgeneration, boosting business productivity and enabling farmers to help decarbonise other sectors of the UK economy

3 Climate change & energy NFU policy The National Farmers' Union of England and Wales (NFU) represents 55,000 members in agriculture and horticulture climate change, energy security and food security converge to provide an opportunity, not a threat to British agriculture Substantial land-based energy resources offer new markets regardless of Brexit, an important element of domestic agricultural policy Nearly two in five farmers (39%) have already diversified into renewables Farmers own or host ~70% of UK solar power, half of AD capacity and the majority of wind power, while playing a significant role in the supply or fuelling of renewable heat ~1250 solar farms / >18,000 PV roofs / 277 biogas plants / ~5000 heating installations / >2600 medium wind turbines Energy storage (and maybe EVs) now set to become part of this trend 500 kw Tesla Powerpack battery coupled to solar roof and 3 car chargers at Lyreco (3 miles away) shows what far-sighted SMEs can do today

4 First examples emerged in 2017 Fast-growing energy service opportunity costs falling dramatically over next 2-3 years, just like solar PV since 2010 at least 1000 MW by 2020; e.g. half utility and half behind-the-meter by 2025, range of estimates ~8000 MW (2x Drax Power): 1000s of installations p: 1 (up Likely range of profitable on-farm applications Glassenbury, Kent 40 MW/28 MWh small to medium sized domestic or commercial systems that capture and release electricity from solar or wind generation easier connection of intermittent renewables to weak electricity networks large (utility-scale) electricity stores, connected directly to the electricity distribution network or coupled to solar/wind farms

5 NFU welcomes emerging opportunities Range of services and business models yet to be developed as potential sources of income Tesla already claim 7-year ROI, peak shaving + FFR enhancing value of existing selfgeneration, avoiding peak use charges market in ancillary grid services role in active network management? permitted development for Energy Barns? although none seen yet vehicle-to-grid two-way charging/storage 1000s if not 10,000s of applications market dominated by batteries; but other energy storage technologies exist (compressed air, flywheels, gravity, etc.)

6 does Clayhill Solar+storage development mean that subsidy-free solar has arrived? clarity still needed on relationship between farmers/ landowners and energy storage providers Are we nearly there yet? regulatory clarification evolving from 2017 Government consultation on A Smart Flexible Energy System opportunities also coming through BEIS Industrial Strategy (e.g. vehicleto-grid) and Defra capital grants under Rural Development scheme

7 Farm technology of the near future? One developer s concept pretty benign? Diesel-electric hybrid tractors, forklifts and telehandlers could participate in vehicle-to-grid network balancing services Based in machinery sheds with solar + storage batteries, earning income towards their charging and maintenance costs
