Ten out sixteen of CEDM’s projects are on electricity related issues
TheRenewElec Project www.RenewElec.org
Develop a family of stochastic simulation models to assess the interaction of elements of different integrated systems Initial framing meetings (project team) Cross check meetings (project team) Combine Workshop and Working Papers into a 1st Set of Policy Guidance & Briefing Materials Use the simulation models to quantify alternative scenarios, using cost, reliability, etc. Produce a more quantitatively informed set of policy guidance materials and briefing documents. Distribute decision tools to key decision makers. Prepare final draft version of project monograph and distribute it widely Arrange for formal publication of the project monograph Review Prior Studies Prepare Working Papers Continue to brief the findings widely to key decision makers 1st integration & Policy Workshop 2nd integration & Policy Workshop First round of largely qualitative policy briefings Begin to frame Continue to revise final monograph final monograph Apr 2010 Oct 2010 Apr 2011 Oct 2011 Apr 2012 Oct 2012 Apr 2013
Current projects - 1 • Network reconfiguration to integrate solar/wind • Decision Makers: LSEs, PUCs • Public engagement for EGS • Decision Makers: EGS developers, permitting agencies, public • Grid stability with large-scale wind • Decision Makers: RTOs, wind developers • Can demand-side management buffer wind? • Decision Makers: utilities, FERC, RTOs • Hurricane risk to offshore wind plants • Decision Makers: wind developers, Offshore Energy and Minerals Management (OEMM), FERC • Solar-thermal integration cost differences from PV • Decision Makers: state legislatures, LSEs • The costs of forecast uncertainty • Decision Makers: RTOs, LSEs, wind/solar developers
Current projects - 2 • Balancing area consolidation • Decision Makers: FERC, LSEs, RTOs, wind developers • Reserve requirements (using non-Gaussian statistics) • Decision Makers: NERC, FERC, RTOs • Environmental implications of coal ramping to follow wind • Decision Makers: EPA, FERC, PUCs • Integrated solar – natural gas plants • Decision Makers: state legislatures, LSEs • G2V • Decision Makers: LSEs, RTOs, FERC, auto makers • Decommissioning requirements • Decision Makers: PUCs, legislatures, wind/solar developers

We have very new data showing that • Solar thermal has substantially better intermittency characteristics than PV. Colleen Horin is going to quantify the integration costs savings that gives.
The 2% recoverable EGS heat-in-place resource estimates are 2,800 times the 2005 total US energy consumption*
The damage map shows where EGS activity can raise public concerns The regions correspond to the high EGS potential regions in purple color in the MIT/Google map.
AltaRock is preparing to drill near Bend, OR* DEL Map The map corresponds to the high EGS region in purple in Oregon from the MIT/Google map.
Only a small portion of locations involve high DEL and number of injuries
EGS can be deployed in many areas in the US… …if geothermal power companies and regulatory bodies cooperate with the public to select socially acceptable sites.
Energy storage is used only to smooth the sharpest wind fluctuationsEric Hittinger Output After Battery “Smoothing” Wind Farm Output
