Overview
• Market forces and trends
• Renewable outlook
• Using storage to manage chaos
• Modernizing the grid
• Crossroads includes renewables and storage
Flexibility for Energy Changing Mix
Energy mix: 2011 - 2035 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

PV Costs Trends and Market GrowthGlobal Solar Market in excess
of $100 Billion
Last year, Wal-Mart announced a partnership with SolarCity to equip California stores with solar panels and has long said it wants to power its stores using
100% renewable energy technologies.

Renewable Generation
• Often inverter based having harmonic contribution
• Intermittent and uncertain generation output
• Interconnection with utility requires power export considerations
• Requires negative load modeling approach

Grid Connected Energy Storage
• Renewable smoothing
• Peak shaving
• Scheduled power output
• Commanded power output
• Power factor regulation
• Commanded VARs

Using Storage to Manage Chaos
• Smooth intermittency
• Minimize reverse power flow, keeps voltage in limits
• Store output and release coincidental with local load
• Control ramp rate
• Primary frequency response, load following

Modern Grid Uses Energy Storage• Storage offers great potential
• Technology is changing! Lithium Ion making great strides.
• Brattle report – Published Nov. 2014. – 3,000 - 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
• 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
Crossroads Includes Renewables, Storage
