GEPL – Many Firsts 1st Independent Power Trading company in India, even before the first electricity trade in the world Executed 1st inter – state contract for power trading in India in 1992 1st to conceptualize and launch a power exchange in India – India Electron Exchange (IEE) in 2004, in association with the Govt. of Goa, ICICI Bank and TPT Inc, USA 1st to successfully trade Wind Power under Open Access 1st to sale Solar Energy to Third Party under Open Access mechanism

GEPL’s Energy Storage Milestones/Objectives/Path Extensive study of various energy storage technologies and applications Regulatory and Policy recommendations, (educating) to a number of state agencies and utilities on energy storage Financial analysis of energy storage solutions Technology Agnostic with focus on getting the best fit solution for energy storage requirements International Collaborations

Association with Younicos Younicos provides integrated Energy Storage Systems combining Track record and experience: Large installation experience of more than 97 MW across the globe and MW-scale micro-grid test center Technology agnostic storage system design and cell-level battery knowledge: Use the battery technology that fits best your application Advanced storage control software: Run several storage services simultaneously and fully automated. Note from Younicos to GEPL: You can mention our cooperation, but please do not state or suggest that it is an exclusive arrangement.

India’s Fuel Mix Coal : 175.2 GW Gas : 24.5 GW Oil : 0.9 GW Hydro : 42.6 GW Nuclear : 5.7 GW Renewable : 38.8 GW Coal : 251 GW Gas : 34 GW Oil : 2 GW Hydro : 61 GW Nuclear : 12 GW Renewable : 175 GW

India’s Ambitious RE Targets 2022 2016 33% 13% 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 20GW of PV Source: NLDC, CAISO

RE Integration – Current Measures Forecasting Balancing Mechanisms Demand Response Strengthen Transmission Regional Power Transactions

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

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 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 Other factors

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 Provide peak capacity Noon Peak Noon Morning Evening Shift 15-50% of daily production on sunny days of PV plants. Reduce fluctuations of PV plants on cloudy days to acceptable limits. 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
