India’s Ambitious RE Targets 2022 Small Hydro Biomass 3% 6% 2016 13% 33% Wind 34% Source: MNRE Solar 57% Wind and Solar – 91% of total RE Capacity

Renewable Energy Impact • Infirm • Unpredictable • Unscheduled generation • Grid instability – frequency and voltage variations • Transmission constraints - excess generation needs additional transmission capacity or else it needs to be curtailed resulting in waste of renewable power. Else thermal power plants need to be laid off to accommodate RE power. • Inefficiency of power system, because of backing down of thermal power plants • Possibility of the California Duck Curve phenomena

The Duck Curve Phenomenon All India Duck Curve assuming 20 GW of PV Source: NLDC, CAISO

Choose the right technology Grid Stability For each application there are many technologies to chose from Power Balancing Energy Balancing

Selecting the appropriate Energy Storage “Solutions” Select as per desired applications Category Grid Stability Power Balancing Energy Balancing Applications • Frequency/ Primary response • Reactive Power/ Voltage Control • PV ramp rate control • Black-start / Islanding • Secondary response • Generation / load management • Short-term load dispatch • • Arbitrage Peak load shifting Peak generation shifting T&D congestion management Other factors Total Life-cycle costs Technical capabilities CAPEX OPEX Usable capacity Response time of Storage system Provide several applications at same time with continuous availability Control Software for grid interaction and quick response

Energy Storage – For Integrating RE to the Grid 1. Dispatchable PV 2. Ramp Rate Control 3. Peak Power Sunny day Cloudy day Peak load: morning and evening “tamed” PV generation Shifted PV generation Noon Peak Shift 15 -50% of daily production on sunny days of PV plants. Noon Reduce fluctuations of PV plants on cloudy days to acceptable limits. Provide peak capacity Morning Evening Provide peak power for 3– 6 hours by charging ESS during off -peak hours. The Younicos storage control software offers these services simultaneously and are fully automated

Energy Storage – System wide usage • • Ensures optimum usage of thermal and renewable generation Increases evacuation capacity for Wind and Solar to achieve renewable targets Reduces transmission and distribution congestion Provides ancillary services
