3 April 2010 New England was one of the first regions to restructure the industry that generates, transmits and delivers electricity. By the late 1990s, all of the New England states, except Vermont, passed legislation to move toward competitive retail markets. Likewise, in 1999, a regional competitive wholesale electricity market was launched. A 2006 report, A Review of Electricity Industry Restructuring in New England found the region s consumers and the environment were better off in comparison to what the prevailing trends prior to restructuring would have yielded had they continued. Since then, several state legislative initiatives have been enacted to refine industry restructuring efforts at the retail level particularly in Connecticut where electricity prices have been the highest in the nation due to heavy reliance on fossil fuels for electricity generation, insufficient infrastructure development in the past that -- up until recently -- resulted in high transmission congestion costs and reliance on uneconomic generating facilities in order to maintain reliability, among other challenging factors.

4 To address these concerns, Connecticut s restructuring efforts were amended through An Act Concerning Energy Independence in 2005 and An Act Concerning Electricity and Energy Efficiency in These statutes were enacted, in part, to reduce electricity prices by: decreasing demand and increasing supply; reducing transmission congestion costs; increasing renewable energy resources to diversify the electricity generation fuel mix; and increasing competition through consumer choice. The (NEEA) retained ESAI Power LLC to assess the effect of these statues on Connecticut s electricity industry. Progress was measured in four broad areas including: generation investment; demand response and energy efficiency; renewable energy resource development; and consumer choice and retail competition. This paper contains the facts and figures that show progress in those areas to be substantial. This information is aimed to help guide the legislative policy debate in Connecticut towards staying the course towards more reliable and affordable electricity supplies through competition.

5 I. Introduction & Summary 1

6 Background and Approach In 1998, Connecticut enacted legislation to restructure its electric utility industry. Since then, several legislative initiatives have been enacted to amend restructuring, with more under consideration. The aim of this report is to review recent performance of industry restructuring to assess progress and help guide current policymaking. The (NEEA) retained consulting firm ESAI Power LLC to compile and present data to assess the impact of two more recent restructuring statutes: Public Acts and (Other statutes have had an additive impact, particularly on renewable energy and energy efficiency initiatives). NEEA advocates for policies to ensure the availability, reliability and affordability of energy supplies which are vital to the region s economic growth and prosperity. 2

7 2005 Restructuring Statute Public Act An Act Concerning Energy Independence The policy objectives of this Act were to: Reduce congestion costs Requests for Proposals (RFPs) process for new resources (generation and demand) Increase incentives for customer-side distributed generation Class III renewable portfolio standard Capital and operating cost subsidies, long-term financing Increase incentives for energy efficiency Class III renewable portfolio standard Same cost subsidies and long-term financing as above Implementation of time-of-use and seasonal rates 3

8 2007 Restructuring Statute Public Act An Act Concerning Electricity and Energy Efficiency The policy objectives of this Act were to: Encourage energy efficiency and conservation Sales tax exemptions, energy efficiency standards for many commercial products, green building code requirements, grants for municipal buildings Increase incentives for renewable energy Increased Class I renewable portfolio standard requirements Net metering Project 150 RFP process to procure 150 MW from CT renewable generators Increase incentives for other generating resources RFP process for peaking generation plants New incentives and extension of existing incentives for distributed generation 4

9 The Combined Policy Objectives of Both Restructuring Statutes Reduce rates by decreasing demand and increasing supply Reduce congestion costs Increase reliance on renewable energy resources Promote customer choice 5

10 Policies Aimed to Address Connecticut s Electricity Rates Currently Highest in New England Source: EEI Typical Bills and Average Rates Report; Summer

11 Greatest difference among New England states is NOT in the competitive (generation) portion, but mostly attributable to distribution and other regulated, non-competitive components Source: EEI Typical Bills and Average Rates Report; Summer

12 Progress of these Restructuring Statutes was Measured in Four Broad Areas With Potential to Lower Rates 1. Generation Investment reduces congestion, replaces expensive generation, increases reliability 2. Demand Response & Energy Efficiency reduces need for infrastructure development and saves consumers money (lowest cost resource available) 3. Renewable Energy Resources decreases reliance on fossil fuels and improves the environment 4. Customer Choice and Retail Competition enables consumers to shop for lower rates as well as for services and technologies offered by alternative suppliers 8

13 Summary of Connecticut Electricity Industry Restructuring Achievements Significant investment in new generation. After a period of significant capacity growth from 2000 to 2004 (1,600MW), there has been a modest increase of 300MW since However, there are currently 4,000 MW of new generation currently under development. If all this capacity is eventually built, the state s total electricity generation capacity will increase by 50%. Substantial reductions in emissions. New generation has primarily been fueled by cleaner natural gas. These new facilities combined with existing fossil generation switching to cleaner fuels, and reduced output due to demand decreases, has cut carbon dioxide emissions from electricity generation by about 20%, nitrogen oxide emissions by 35% and sulfur dioxide emissions by 50%. Dramatic increases in energy efficiency and demand resources. Over 400 million kwh of electricity are saved each year from consumer-funded utility efficiency programs. This is enough electricity to power over 47,000 homes. Energy efficiency and demand resources are becoming a large portion of the state s energy resource mix. 9

14 Summary of Connecticut Electricity Industry Restructuring Achievements (Cont.) Development of renewable energy resources. The state s renewable portfolio standard requires electricity suppliers to purchase increasing amounts of electricity from renewable resources 27% of total electricity load by To date, there have been moderate increases in renewable resource development, mostly from biomass resources. There are several hundred megawatts of renewable generation being proposed including landfill gas, hydro, biomass and wind. Escalating success in retail competition. Since 2005, there has been triple-digit growth in the number of customers served by competitive suppliers, particularly in the residential sector. Today, alternative suppliers serve almost 20% of all customers and half of all electricity sold in the state. 10
