The Solution?
11The Solution?
• Many different offerings
• Energy storage:
• Grid scale
• Co-located with renewables
• Behind-the-meter
• Commercial & Industrial
• Residential

The Energy Storage Market
13The Energy Storage Market
Market disruption – falling cost of batteries
14The Energy Storage Market
• Deployment in the UK & Irl is relatively low
• 24 operational sites (excluding residential)
• Ranging from 0.005 to 10 MW in power output
• Six of these have been built by Northern Powergrid
• CLNR project
• Majority based on the Li-ion technology
• Majority commissioned during the last two years
* 2016 figures, Ref: Eunomia, Investing in Electricity Storage, Jan 2016
15The Energy Storage Market – Use Cases
DSO Services Behind the MeterCo-Location with
Renewables
Arbitrage Use of System Charges Reduction
Reinforcement Avoidance Ancillary Services
16
• Kilroot Power Station
• Planned 100 MW energy storage array
• Operational 10 MW Li-ion battery
• Primary, secondary and tertiary operating reserve contract for 2017
Grid Scale
17
• Economics remain challenging
• Arbitrage and ancillary services mix
• Short term contracts for ancillary services (UK)
• Change of connection agreement (hybrid site)
• Capacity vs MEC restrictions (max (120% of MEC)
• Access to FiT tariff?
Co-Located With Renewables
18
• Peak shifting, use of system charge reduction, self consumption of onsite renewables
• Strong corporate responsibility drivers
• Spend-to-save mentality
Commercial & Industrial – Behind-the-Meter
19
• Residential lithium-ion battery can store enough energy to power a home for a full day
• 50,000 residential systems sold in Germany in the last four years
