3 Overview Market forces and trends Renewable outlook Using storage to manage chaos Modernizing the grid Crossroads includes renewables and storage

4 Flexibility for Energy Changing Mix Energy mix: Natural gas: 21% to 40% Coal: 49% to 25% Renewables: 4% to 11% Infrastructure implications: Changes how we make, move, and use power Must accommodate renewables, build in flexibility Source: Black & Veatch Analysis - Energy Market Perspective

15 Modern Grid Uses Energy Storage Storage offers great potential Technology is changing! Lithium Ion making great strides. Brattle report Published Nov ,000-5,000 MW of distributed electricity storage is most cost-effective across ERCOT at $350/kWh storage cost. Payback dependent on both regulated investment deferral and merchant/market value of the energy Proposes that T&D companies can deploy storage on the distribution system and "auction off" rights to third parties to participate in the wholesale market

16 Crossroads Includes Renewables, Storage Recognize market forces. Industry at crossroads. Energy mix is changing! Regulatory shifts are certain Technology advancement is accelerating storage and renewables Represents an opportunity to remain competitive and manage uncertainty Wanda Reder Chief Strategy Officer S&C Electric Company (773)
