1 MARCH 2018 Battery Energy The power to control the energy Marcus Sousa, Territory Market Manager, Europe

2 Challenges of the future power grid Long-term drivers for energy storage Electricity consumption on the rise Electrification of everything moving towards electricity as the primary source of power Economic and population growth will lead to increasing demand for power Coal plant retirements Reducing baseload power capacity Limited resources for ancillary services on the utility grid Growth in renewables Governments and industry moving towards solar and wind Intermittent generation sources can reduce reliability on the electrical grid Electrification of transportation More users of EVs can increase peak loads placing more strain on the electrical grid Increase in high speed rail Proliferation of smart grid technology Bi-directional flow of power requires additional coordination between power supply and demand Tax and regulatory incentives Renewable mandates and incentives increasing demand for clean grid technologies Potential tax benefits for storage systems (residential, commercial and utility) March 6, 2018 Slide 2

3 Battery energy storage systems Used today across various industry segments, behind and in front of the meter applications Generation Grid Transport Higher reliability rail and e-bus network Postponement of grid upgrades Integration of distributed renewables & EV Dispatchable renewables = more $ per kwh Industry and large commercial Reduced fees from harmonic pollution & demand peaks Microgrids Stabilization Residential and small commercial New revenue from ancillary grid services Optimize self-consumption March 6, 2018 Slide 3

4 Market segments and their main characteristics Majority of use cases expected to be behind the meter deferral of investments but business case not always present Grid services regulations do not allow in many markets Combined with renewable plants to reduce fluctuations and further improve dispatchability Mitigates trading risks when integrated in fleets of generators Good complement with renewables powered microgrids Key element for securing system stability and resiliency Battery energy storage Addresses capacity and peak consumption issues Improves power quality and can reduce energy bill Used in combination with solar roof top to gain energy independency or reduce energy bill Enabler to enable fast charging at home Enables fast charging in cities and weak points of the grid Together with bidirectional smart charging, enables the vehicle to grid (v2g) concept March 6, 2018 Slide 4
