The Cost & Impacts of New Environmental Regulations and the Opportunity for a New, Cleaner Electrical Grid (Project No ) Cyrus Reed Conservation Director Lone Star Chapter, Sierra Club

ERCOT Study Incomplete and Flawed Opportunity for PUC and ERCOT to take steps now to position yourself for future challenges Continue Push for Transformative Technologies Air Quality and Water Resource Challenges are Real under Present Electric Resources Commit to a plan for more complete report and recommendations to Legislature in 2013 Overview 2

Incomplete List of Upcoming Regulations – Ozone and Haze could be big deals; Supreme Court case opens up potential for global warming regulations in September Previous Studies suggest much greater pain on coal industry, including in Texas Coal companies & utilities already reacting to these regulations and increasing costs by examining retire vs. retrofit Some utilities in Texas already considering retirements ERCOT Study Incomplete and Flawed 3

Previous Studies Show Much Greater Impact and Costs 5 Synaps, Replace with Gas

Just the facts from the studies Brattle Study – some 13,000 MWs of coal plants in Texas might become unprofitable if forced to add equipment Sanzillo Study – Debt levels plus $3.6 billion in retrofit costs make Big Brown, Monticello & Martin Lake plants worthless Bradley study – Texas Region has 28,889 MW of CC Natural Gas above 500 MWs that is underutilized (44%) and could replace older coal plants CPS Energy said it prefers retiring Deely rather than add some $500 million in scrubbber and air pollution costs – ERCOT study list only $34 million in costs 6

Since October 2008 only 1 coal plant has broken ground for construction - the Kemper IGCC plant in MS A total of 48 existing coal plants were announced for retirement in 2010, to be replaced with cleaner burning fuels, renewable energy, and energy efficiency. In late 2010 Colorado established a plan to shut down 902 megawatts of existing coal capacity. The plan was approved by the Colo PUC and the retirements start this year (2011). In June 2011 American Electric Power, one of the country's largest consumers of coal, announced a plan to retire 25% of its coal fleet (includes a unit at the Welsh Plant in Pittsburg, TX). Announced coal plant retirements in 2010 in Colorado, Arizona, Utah and Oregon will result in the retirement of nearly 10% of the entire Western coal fleet. In April 2011 Washtington state Governor Chris Gregoire signed a bill that will end all coal burning in the state by The Energy Information Agency now projects that no new coal plants will be built in 2011 without significant incentives. CPS Energy announces plan to end Deely by 2018 or sooner Coal Already On the Brink? 7

The Case for Retirement of Coal Plants Weak financial fundamentals: Prolonged natural gas/low power prices. Wind competition. Questionable Long-Term Outlook/Shaky revenues. Environmental liabilities -- $3.6 Billion: the case for retirement done. Major water user and creator of ozone in Dallas region Private equity deal makes retirement priority. Keeping the Lights On Graduated Shutdown. 5,280 MW manageable. Natural Gas reserves and new construction. ERCOT Planning: Other Generation and Energy Resources.

Take concrete steps today to position yourself for future challenges Implement SB 1125 Sooner Rather than Later Transition to 0.4% of peak demand goal Allow more varied and direct energy efficiency programs Encourage ERCOT to adopt rules now to allow market-based demand response programs – PJM has tripled DR over last five years Work with SECO to implement reporting requirements of SB 898 and SB 924 (energy efficiency goals and reporting by political entities, Cooperatives and Municipalities) Work with SECO and ESL to incorporate building code efficiencies into planning and forecasting (HB 51) Continue to push for better demand and supply forecasting short and long-terms – incorporation of building codes, EE programs, demand side, etc. With Great Power Comes Great… Opportunity! 10

Air Quality and Water Resource Challenges are Real and Part of Answer will be New Cleaner Electric Grid Reducing emissions from rural power plants by adding on SCRs or retiring these old plants may be far less expensive than cleaning up urban sources 14

Water availability is expected to decline by 35% The current drought throughout Central Texas sets the trend for what we can expect in the future. Droughts are expected to get worse and thus energy sources that require little or no water will be far more viable Water Needs for Electricity are Real and so too is Drought and other needs National Drought Mitigation Center 15

Follow this workshop with a commitment to plan for the future like it or not, the federal rules are what are or will be Question is how will Texas position itself to provide the clean, affordable, reliable energy its economy needs? nothing prevents PUCT from collaborating with RRC, TCEQ, TDHCA, TWDB, SECO and other state agencies to assess our position and plan for success Plan for the Future 16

Use PUC study proposed in SB 15 as a blueprint for an approach Consider an 18-month timeline for this report, include collaboration with RCT and TCEQ Include public process, including potential for advisory committee – use utilities and interested parties to do your work for you identify the tools you will need to address these issues before the 83rd Texas Legislature convenes and make sure state leaders understand these challenges and the options to address them. Be prepared to answer the questions by January of 2013 and what recommendations are needed May need to look at retirement strategy and transition strategy for early retirement, including use of natural gas reserve capacity Forgiveness for environmental sins including consent decrees for reliability only Purchasing commitment for state needs Use of state credit for loan guarantees for transitional resources Plan for success 17
