  3. Clean Coalition Vision = DG+DR+ES+EV+MC2

  4. Clean Coalition Overarching Objectives • From 2020 onward, at least 50% of all new electricity generation in the United States will be from local sources. • Locally generated electricity does not travel over high voltage transmission lines to get from the location it is generated to the area it is consumed. • From 2020 onward, at least 80% of all new electricity generation in the United States will be from renewable sources. • By 2020, policies and programs are well established for ensuring successful fulfillment of the other two objectives. • Policies reflect the full value of local renewable energy. • Programs prove the superiority of local energy systems in terms of economics, environment, and resilience.

  5. Wholesale DG is the Critical & Missing Segment Central Generation Serves Remote Loads Project Size Wholesale DG Serves Local Loads Retail DG Serves Onsite Loads Behind the Meter Distribution Grid Transmission Grid

  6. WDG Delivers German-scale Solar Markets Solar Markets: Germany vs California (RPS + CSI + other) Cumulative MW Sources: CPUC, CEC, SEIA and German equivalents. Germany added nearly 15 times more solar than California in 2011, even though California’s solar resource is 70% better!!!

  7. SMUD CLEAN Program: Showing the way in U.S.

  8. What is an Incentive for Wholesale PV? • Program capacity • RPS • FIT • Clean Local Energy Accessible Now (CLEAN) Programs • FIT + streamlined interconnection • RFP / Auction • Standardization and transparency • Standard, must-take PPA • Streamlined interconnection • Pre-mapping, utility pays, cost-averaging • Deterministic pricing • Equal treatment • Passive loss rules (IRS Section 469 unfair to renewables) • Property tax exemptions (Texas unfair to wholesale)

  9. Where are Best Incentives for Wholesale PV? • CLEAN / FIT Programs replicating across the United States • Long Island, Fort Collins, Vermont, etc • CLEAN / FIT Programs in California • RAM in California (limited by interconnection prerequisites) • Georgia Power • CLEAN / FIT • RFO • Promising legislation / signals • Arkansas • Iowa • Minnesota • Oregon • Michigan

Local CLEAN Program Guide Free download:http://www.clean-coalition.org/local-actionContact us: LocalGuide@Clean-Coalition.org Modules of the Guide: Overview & Key Considerations Establishing CLEAN Contract Prices Evaluating Avoided Costs Determining Program Size & Cost Impact Estimating CLEAN Economic Benefits Designing CLEAN Policies & Procedures Gaining Support for a CLEAN Program

  25. CLEAN Programs Defined • CLEAN = Clean Local Energy Accessible Now • CLEAN Features: • Procurement: Standard and guaranteed contract between the utility and a renewable energy facility owner • Interconnection: Predictable and streamlined distribution grid access • Financing: Predefined and financeable fixed rates for long durations • CLEAN Benefits: • Removes the top three barriers to renewable energy • The vast majority of renewable energy deployed in the world has been driven by CLEAN Programs • Allows any party to become a clean energy entrepreneur • Attracts private capital, including vital new sources of equity • Drives local employment and generates tax revenue at no cost to government

  26. German Solar Pricing Translates to 7 cents/kWh Source: http://solarindustrymag.com/e107_plugins/content/content.php?content.10624, June 2012 • Conversion rate for Euros to Dollars is €1:$1.27 • California’s effective rate is reduced 40% due to tax incentives and then an additional 33% due to the superior solar resource Replicating German scale and efficiencies would yield rooftop solar at only between 7 and 10 cents/kWh to California ratepayers

  27. US has far better solar resource than Germany

  28. Installed PV Costs in US vs Germany Sources: LBNL, PwC, and Forbes; Sep2012 Rooftop solar project installation costs are roughly 2.5 times higher in the US than in Germany

  29. Avoided Transmission in CA = $80 Billion over 20 yrs Business as Usual Year-20 TAC (TAC20 ) = 2.7 2.7 Business As Usual TAC Growth Current TAC Rate (TAC0) = 1.2 TAC0 O&M Level Business as Usual TAC Growth TAC0 Depreciation + O&M Avoided TAC Opportunity from DG

  30. CLEAN Avoids Hidden Transmission Costs “Palo Alto CLEAN will expand clean local energy production while only increasing the average utility bill by a penny per month” -- YiawayYeh, Mayor of Palo Alto

  31. CLEAN-Gainesville Starts a US Solar Revolution

  32. CLEAN Delivers Ontario’s Goals • On track to replace 100% of coal power by 2014 • Created tens of thousands of jobs, and on track to create 50,000 jobs • Attracted over $20 billion in private-sector investment to Ontario • More than 30 companies are currently operating or plan to build, solar and wind manufacturing facilities in Ontario 6 GW Coal Power

  33. SMUD Proves CLEAN is Superior for California CLEAN = FIT + streamlined distribution grid interconnection: • Interconnection of wholesale distributed generation projects to California investor owned utility distribution grids takes an average of 2 years. • In contrast, interconnection to Sacramento Municipal Utility District’s (SMUD) distribution grid takes an average of 6 months. • Two SMUD staff members completedinterconnection studies for 100 MW CLEAN Program projects in 2 months. • SMUD maximized transparency bypublishing online interconnection maps. • 100 MW of WDG projects were built in 2 years with no ratepayer impact.This is equivalent to 2.5 GW of cost-neutral WDG across California.

  34. DG+IG Backup Slides DG+IG Backup Slides

  35. DG+IG Initiative = Proving Feasibility of High DG • Work with five utilities across the US to deploy a DG+IG demonstration project at each by yearend-2014 • Prove viability of Distributed Generation (DG) providing at least 25% of total electric energy consumed within a single substation grid area • Integrate Intelligent Grid (IG) solutions to ensure that grid reliability is maintained or improved from original level • IG solutions includediversity and Energy Storage for sure, and potentially, advancedinverters, forecasting & curtailment, and/or DemandResponse

  36. DG+IG Initiative = Proving 50% Local Energy Goal

  37. Benefits of DG+IG • Reliability benefits • Increased customer satisfaction • Improved equipment longevity • Potential Resiliency/Security benefits • Sustained vital services • Avoided transmission dependencies • From imported energy to local energy • Economic benefits • Large private-sector investment • Significant local job creation • Fixed electricity prices for 20+ years • Localized energy spending • Environmental benefits • Utilizing built-environments and disturbed lands for generation projects • Preserving pristine environments from transmission lines and other infrastructure

  38. DG+IG Projects Begin with Grid Modeling & Simulation

  39. DG Diversity Greatly Reduces Variability Source: Clean Energy Maui, Feb 2011

  40. Power Factor Benefits need to be Compensated Example (0.85 PF): S = 1 MVA P = 0.85 MW Q = 0.5 MVAr P/S = 0.85 = Power Factor NOTE: A 15% reduction in real power leads to 50% of reactive power. Sourcing (or sinking) reactive power at the inverter can provide control of local voltage levels – a significant locational benefit not incentivized by current policy. Policy must be updated to reward the full range of locational benefits that distributed energy resources can provide. P: “Real Power” consumed by load, used by utility billing and solar PPA Q: “Reactive Power” used to induce magnetic fields for inductive loads (motors, compressors, etc.) S: Apparent Power must be generated and distributed to support the total Real and Reactive loads REACTIVE 50% potential Q S Q P REAL 15% P loss
