Battery Energy StorageThe power to control the energy
Marcus Sousa, Territory Market Manager, Europe
Long-term drivers for energy storage
Challenges of the future power grid
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)

– deferral of investments but business case not always present
– Grid services – regulations do not allow in many markets
Majority of use cases expected to be behind the meter
Market segments and their main characteristics

– Good complement with renewables powered microgrids
– Key element for securing system stability and resiliency
– Used in combination with solar roof top to gain energy independency or reduce energy bill
– Enabler to enable fast charging at home
– Combined with renewable plants to reduce fluctuations and further improve dispatchability
– Mitigates trading risks when integrated in fleets of generators
– Addresses capacity and peak consumption issues
– Improves power quality and can reduce energy bill
– Enables fast charging in cities and weak points of the grid
– Together with bidirectional smart charging, enables the vehicle to grid (v2G) concept

Energy storage applications description
March 6, 2018 Slide 6
– The provision or absorption of short bursts of power to maintain the balance of supply and demand & [hence] the frequency
– Often procured by the system operator
Utility Storage Applications
Frequency regulation
Peaking capacity
Renewable integration
Transmission load levelling
Distribution load levelling
– The provision of capacity to meet demand peaks
– Storage connected to renewable generators (solar, wind) in order to smooth the output before connection to the grid
– Investment deferral: installed in the transmission grids, as alternative to increasing the capacity of one or more lines
– Can also be used to improve power quality (reactive power compensation)
– Investment deferral: installed in the distribution grids, as alternative to increasing the capacity of one or more lines
– Can also be used to improve power quality (reactive power compensation)
– Energy storage integrated with residential & commercial roof top solar PV
– Main application is to increase % of self-consumption
Behind-the-meter:
PV + storage
– Energy storage for commercial and investment customers
– Main application is to reduce peak demand charges
Behind-the-meter:
Peak shaving
