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
More flexibility
Accommodate distributed renewables
Technology Changes Things!
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.

Global Solar Market in excess of $100 Billion
David Crane, CEO, NRG April 30, 2014
Crane expects many American residences to go “off the grid” within two years as reliance increases on natural gas and solar panels. He said it is easier and and cheaper for many more residents to have
devices that convert the natural gas into electricity, to add solar panels to homes and to "tell the electric company to get lost." The
trend will start in the Northeast and spread nationwide, he said.

Modern Grid Uses Energy Storage
• Storage offers great potential for grid: cost and useful life have been barriers • Technology is changing! – Lithium Ion, has made great strides. – Becoming affordable•
Brattle report:
– Analysis shows that ~5,000 MW of distributed electricity storage is most cost‐effective across ERCOT at $350/kWh storage cost. – Payback dependent on regulated investment deferral and merchant/market value of the energy Community Energy Storage 25 kW; 50 kWh Lithium-Ion Mid-Sized Energy Storage 250 kW; 250 kWh Lithium-Ion19
