  1. The Institute of Healthcare Engineering and Estate Management Alternatives to Grid Connection: Energy Storage: David Surplus Chairman, B9 Energy Group

  2. Lecale DSU Build-up DDFFRE

  3. 11kV Network (3-phase)

  4. Lecale DSU “Lecale” Aggregated DSU for 11kV circuits 33kV sub-station (Community Sub-station) ICAES (N I Energy Storage Demonstration Park) Farm scale AD 250kW wind turbines Solar PV Anaerobic Digestion 2nd life traction battery charging Ammonia production 300 houses + EVs as a captive customer base • NB: Ammonia can power... • Tractors • Fishing boats • Ferries • Standby gen-sets upsold as... • Peak lopping gen-sets • Aim to be self-sufficient in electricity • Aim to have cheaper, greener and more secure power supplies • More than 70 x rural 33kV sub-stations in NI “Seagen” Tidal test site

  5. Compression is hot business

  6. “Isothermal Compressed Air Energy Storage” Stores heat as well as compressed air

  7. First-Generation Product Shipping in Q1-2015 Breakthrough Price and Service Life Power Unit • 500 kW modules • 70% round-trip efficiency • 20+ year lifetime • Selling price ≈ $1000 per kW Storage Unit • 1 MWh modules • Proprietary filament-wound tanks • Shipping container form factor • ASME certified • Selling price ≈ $200 per kWh LightSail Energy Confidential

  8. Small wind planning applications

  9. Small wind planning applications Offshore windfarm

  10. Microgrid revenue streams... • Arbitrage – Buy at £20 to £30 / MWhr Sell at £80 to £250 / MWhr • “Load on Demand” services to avoid external curtailment (30% of wind strike price?) • Direct sales on long term fixed price (+RPI) basis • Consideration for avoided cost of grid upgrade • Ancillary services: Reactive power management Voltage regulation Possible provision of inertia • Capacity market payments

  11. Other microgrid benefits... • Additional microgrid revenues allow voluntary reduction of ROC revenues on single generator projects – easing price rise pressure • Security of supply to load customers is improved • Autonomous operation possible - to ride through central system blackouts if necessary

  12. Internet Wireless Connection AC DC Ethernet Home scale Microgrid

  13. Industrial scale microgrid
