Energy Exchange : Federal Sustainability for the Next Decade 5 A Realistic Approach to the Holistic Strategy A Holistic Energy Strategy Traditional Power Renewable Integration Demand Side Management Energy Storage Budget Neutral Microgrid Electricity, Gas, Hydroelectricity Solar, Wind, Geothermal Load Response, Energy Efficiency Fuel Cells, Electric/Thermal Energy Storage By employing a holistic approach to your energy strategy – evaluating project economics in aggregate with respect to mission requirements – you can achieve budget neutrality and project deployment. A holistic energy strategy has consideration for adaptable distributed generation capabilities allowing bases to “plug and play” as a result of circumstances (threats, breaches, attacks, etc.) affecting an installation.

6. Energy Exchange : Federal Sustainability for the Next Decade 6 The Energy System of the Future Conventional baseload generation is being squeezed. The combined impact of increasing renewables penetration to serve U.S. load and increasing distributed generation, with continued energy efficiency improvements shaving load growth, lowers the value of centralized conventional baseload generation over the next 10 years. http://www.constellation.com/pages/technology-ventures.aspx Water scarcity for power generation is increasing – the energy/ water nexus. Drives constraints on the choice and siting of power generation. Natural gas supply and consumption increase for the foreseeable future. Natural gas continues to gain market share at both domestic and global levels. Consumer behaviors are changing and pushing toward a decentralized system. Distributed Generation penetration increases from less than 2% currently to approximately 10% by 2025. The intelligent electric network is emerging. Smart Meter installations will grow to more than 65 million U.S. homes by 2020 (greater than 50% adoption). 1 2 3 4 5
