2. Outline
Decentralized Energy - Governor Brown’s Clean Energy and Jobs Plan
Momentum - Utility Scale Renewable Energy
Acceleration - Building Integrated Electric Systems
Managing Diversity - Communities at the Energy Crossroads
Convergent Industries – Energy and Information

3. Governor Brown’s Clean Energy and Jobs Plan – Renewable Integration Elements
Build 12,000 Megawatts of Localized Electricity Generation Build 8,000 Megawatts of Large Scale Renewables & Necessary Transmission Lines Deal with Peak Energy Needs and Develop Energy Storage Create New Efficiency Standards for New Buildings Make Existing Buildings More Efficient Adopt Stronger Appliance Efficiency Standards Develop 6500 Megawatts of Combined Heat & Power (CHP) Projects Appoint a Renewable Energy Jobs Czar

6. Long Term California Utility Scale Renewable Electricity Supply Portfolio
High temperature thermal energy storage can be used to configure concentrating thermal power plants
for peaking, intermediate and even seasonal base-load capability. Off shore wind plants have higher capacity factors and greater predictability than on shore plants. Geothermal plants can be configured for ramping capability.

9. Renewable Energy Secure Community (RESCO) Building Blocks
California wants all new residential and commercial buildings to be net zero by 2020 and In some contexts, net zero communities may make even more practical and economic sense. Relative to large renewable power plants, community based renewable sources may help avoid rather than require new electric transmission infrastructure. They bring into play high quality clean energy resources that would not receive development attention otherwise, in many cases with locally acceptable or negligible environmental impact.

10. Economic Impact of Indigenous Energy
Iceland is a volcanic island and a micro-state surrounded by the North- Atlantic Ocean ( km2) with a total population of only inhabitants (cf. California at 403,934 km2)
During the course of the 20th Century Iceland changed from being among Europe’s poorest countries, depending upon peat and imported coal for its energy, to a country with the world highest living standard (with Norway)
A substantial part of Iceland prosperity in the latter half of the 20th century can be attributed to increased use of indigenous renewable energy sources
Iceland is now on a mission to eliminate the use of fossil fuels over the next few decades

11. West Village Energy Initiative Goals
• Affordable living for 5000 UC Davis faculty and students
Zero net energy from the regional grid on an annual basis
• Hyper energy conservation measures
• Multiple community scale
renewable resources
• Smart grid functionality
• No higher cost to the
developer or customer
First phase in construction

12. 21st Century Renewable Energy Deployment Scenarios

13. 20th Century Grid Centralized electricity supply
One way power flow at the meter and up-stream
“Revenue” metering
Price signals packaged in monthly bills
Consumer cost build-up:
Electric and gas energy priced according to usage period
Capacity priced according to peak demand during billing period
Indirect costs allocated according to customer category
Regulatory interest in protecting the utility’s access to low cost capital

14. Relevant Models and Concepts
Adaptive:
Transformative:
Smart Sub-station
Distributed Utility
Net metering
Demand Response (DR)
Micro-grid
Virtual Power Plant
Virtual Net Metering
Integrated Renewable Energy Systems
Net Zero Energy and/or Renewable Energy Secure Buildings
Net Zero Community (Energy or Carbon)
Renewable Energy Secure Communities
Continuously Dispatchable Demand Response
Microgrid Networks
Adaptive = Utilities and regulators lead implementation
Transformative = Energy consumers and competitive energy suppliers lead implementation

15. 21st Century Grid Distributed and centralized electricity supply
Bi-directional power flow at the meter and upstream
Pervasive “net” metering and “smart” meters
Actionable real time price information plus automated response at the point of use
Consumer cost build-up:
Electricity and gas purchases for specific uses at specific times
Levelized payments on energy supply and efficiency investments
Opportunity costs related to “use or sell” decisions
Policy interest in infrastructure modernization

16. Conclusions - 1
California can pioneer the effective integration of utility, community and building scale renewable electricity generation, using natural gas as a bridge fuel.
Utility scale solar, high temperature storage, off shore wind and new geothermal resources will allow reliable and efficient operation of California’s current high voltage transmission system
California’s current transmission infrastructure must be modernized to accommodate this low carbon supply mix

17. Conclusions - 2
The market for building integrated electric systems able to charge electric vehicles and optimize the economic value of integrated supply and storage can accelerate rapidly where it is enabled to operate.
Communities will be at the nexus of energy infrastructure transformation and have the opportunity to gain economic advantage by learning to manage an expanding diversity of new energy supply, delivery, usage and financing options.
Energy related industries will be a market for information industry solutions, opening major opportunities for both.
