    • SMART GRID A Regulatory Perspective Matt Baker CommissionerColorado Public Utilities Commission
    • Types of Colorado Electric Utilities Colorado Energy Sales by Type of Utility Public 17% Investor-Owned 55% Cooperative 28%2
    • Electric Generation Fuels in Colorado 1990-2008 Colorado Electric Generation by Fuel Source 1990-2008 70,000 60,000 Renewable 50,000 Gigawatthours NG 40,000 30,000 Hydro 20,000 Coal 10,000 0 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 20083
    • History of Colorado’s RPS• Amendment 37 (2004) – Voter initiated; 10% renewable energy by 2020; separate solar requirement; net metering• HB 1281 (2007) – 20% renewables by 2020; 10% for municipal utilities and cooperatives; solar requirement• HB 1001 (2010) – 30% by 2020; carve out for DG of 3% by 2020 (~650 MW PV)4
    • Xcel Energy• ~7000 MW peak load• 2004-present – 1,200 MW wind capacity – 60 MW solar capacity• By 2015 – Additional 750 MW wind capacity – >250 MW new solar thermal – >160 MW new photovoltaic5

    • PUC Smart Grid Activity
    • Smart Grid Defined Source: Electric Power Research Institute. “The Green Grid: Energy Savings and Carbon Emissions Reductions Enabled by a Smart Grid.” May 2008.
    • What is Smart Grid? A Broad Definition:  Overlay of Bi-Directional Communication and Control Mechanisms onto the Electricity Grid  Marriage of Electricity Grids with Information Technology  Involves the entire electricity value chain:  Generation  Transmission  Distribution  Consumption Smart Grid is an enabler:  Demand Response  Efficiency  Renewable Integration (central and distributed)  Plug-in Hybrid Electric Vehicle (PHEV) Integration  Consumer Choice
    • Smart Grid Enabled System Electricity providers will have greater access to real-time information about the state of the system from generation to consumption Electricity providers will have greatly increased ability to control both supply and demand Consumers will have information about the cost and environmental attributes of their electricity and the ability to automate efficiency Department of Energy, National Energy Technology Lab http://www.netl.doe.gov/moderngrid/opportunity/vision_characteristics.html
    • 21st Century Electricity System• Information rich• Distributed design and operation• Clean tech priority• Ubiquitous storage• Automated operations• Highly differentiated energy services Source: Steve Hauser, NREL
    • Transitional Challenges Complex array of potential technology choices. Smart Grid technology (equipment and software) will be a moving target in the near term. Industry consolidation already occurring. Attrition likely as dominant providers emerge. Interoperability standards are critical. Consumer education and adoption extremely important, very uncertain. Regulatory landscape  Balkanized regulations (Federal, State, local) will lead to deployment and integration challenges.
    • The Built Environment• How can smart grid lower costs?• What revenue centers will it provide? – HVAC – Energy management – Energy production – PHEVs . . .• How do codes and regulations enable progress? – Implications to utility law? • vertically integrated versus componentized approach?
    • Urban Context• T&D efficiency gains – i.e., distribution automation• Building energy efficiency• Microgrids – small, integrated energy systems in which generation and load are co- located – can operate in parallel with the grid or intentionally islanded• Energy Storage – Utility scale or localized• Renewables Integration• Electric Vehicles – Vehicle to Grid (V2G) – Charging infrastructure – Parking Z. Ye, et al. Facility Microgrids, National Renewable Energy Laboratory http://www.nrel.gov/docs/fy05osti/38019.pdf at 1.
    • Smart Grid: Regulatory Evolution• Regulatory landscape must keep abreast of innovation – Should promote -- not stymie -- investment• Investors – Who has the expertise? – Who takes the risk? – Who owns smart grid infrastructure components?• What codes, standards will apply?• How to ensure cyber security?
    • Regulatory Incentives• As with EE and DSM, utilities need incentives to invest in technology that decreases sales – Decoupling – Dynamic rate structures – But cost recovery for infrastructure investments• Which investments require a CPCN?• Which do not?• Who pays? – Minimize risk to ratepayers
    • Conclusions: Going Forward• Smart grid offers promise and benefits – But also some risks• Do what makes economic sense now – T&D upgrades are cost effective• Come to us with pilots• Allow third parties to work with business owners and homeowners to achieve greatest gains
