1 CL&P s new time-of-use (TOU) rates

2 WHY Why are these new TOU rates being implemented? To provide customers with a new opportunity to achieve a benefit from shifting consumption to off-peak periods. Current TOU pricing for large commercial and industrial customers is based on a peak period of 7 a.m. to 11 p.m., weekdays. Historical load data shows that peak demands generally occur between 12 p.m. and 8 p.m. on weekdays. The new TOU period allows peak period pricing for power to be more aligned with the time of day that high prices and high peak demands occur. As CL&P procures energy for serving its large commercial and industrial customers in the future, we will be required to set a larger peak/off-peak generation service price differential than exists under current TOU rates.

3 WHat What can or should I do? Understand your consumption patterns and plans for electricity usage. If you are a CL&P commercial or industrial customer, this may provide an opportunity for your company to consider shifting some of your workday schedule. If you receive service under CL&P Rates 41, 55, 56, 57 and 58, here are some actions you should take in preparing for the implementation of the new TOU rate structure: Verify that your facility s energy management system is operating correctly and adjust controls as necessary. Make sure that all control points are operational and are set to minimize electric demand, especially during peak hours. Special attention should be paid to the following areas: Temperature set-points. Operating schedule that matches the occupancy schedule. Outside air supply that matches the occupancy requirements. All air dampers and valves are functioning properly. Maintain heating, ventilation and air-conditioning (HVAC) equipment and systems to achieve peak performance. Leaks and unwanted flow restrictions should be eliminated. Evaluate changes to the lighting, HVAC and hot water systems to improve the facility s overall efficiency. Evaluate adding control functions to reduce electric demand/electric energy consumption while maintaining occupant comfort and productivity. Evaluate changing the operating schedule of high demand equipment or adding technologies that shift electric demand to flatten out the load profile. Implement changes to turn off electrical equipment and systems when they are not required for production, occupant comfort or safety. Implement changes to the facility s equipment and systems and replace existing equipment with higher efficiency equipment. Document the operating conditions established for each area of the facility under all anticipated modes of occupancy. Train operating personnel and maintenance personnel in the proper operation and maintenance of the building s systems. Create a feedback mechanism between the people who see the energy bills and those who operate and maintain the facility.

4 how cl&p can help There are Connecticut Energy Efficiency Fund programs that can help customers adjust to the rates and new on-peak period. Additional information can be obtained on the CL&P Web site ( or by calling WISE-USE ( ). DEMAND REDUCTION is designed to provide incentives for the installation of equipment and controls that reduce kilowatt (kw) demand through realtime monitoring. CL&P will review all projects/proposals and provide incentives for cost-effective projects that provide peak load kw and kilowatt-hour (kwh) reductions in commercial and industrial applications. ENERGY OPPORTUNITIES is designed to improve the energy efficiency of existing commercial and industrial facilities by capturing retrofit opportunities. Retrofit projects are defined as those where the customer voluntarily exchanges or modifies inefficient, functioning equipment with high-efficiency alternatives. CL&P will review all projects/proposals and provide incentives for up to 60 percent of the installed cost. Projects/proposals may also qualify for a bonus incentive for comprehensive projects. ENERGY CONSCIOUS BLUEPRINT is designed to encourage the installation of energy efficient measures when most cost-effective at the time of construction or end-of-life replacement. CL&P will provide incentives to cover up to 100 percent of the incremental cost of more efficient equipment and systems. PUBLIC ACT also provides incentives to encourage customers to install distributed generation systems at their facilities. Distributed generation may help reduce load and result in reduced demand charges during peak periods. CL&P will assist the customer with their application to the Department of Public Utility Control. cl-p.com How can I learn more? Your CL&P Account Executive is ready to work with you to make the transition to the new time-of-use rates as easy as possible. The Comparative Bill Analysis is intended to provide an indication of the bill savings achievable once the new TOU periods are implemented starting January 1, 2008 and usage is shifted from the new peak to the new off-peak periods. A customer-specific analysis is also available via an online calculator. This allows a customer access to their historic load data, and the ability to view changes to their on and off-peak usage resulting from the new time-of-use periods. Please contact your CL&P Account Executive for access to the online calculator.

5 new time-of-use (TOU) rates NEW on-peak (Weekdays): 12:00 p.m. 8:00 p.m., EST NEW off-peak: All other hours, including weekends On January 1, 2008, Connecticut Light and Power (CL&P) will begin implementing new time-of-use (TOU) rates for its customers. While the implementation of new TOU rates for all customers will take several years, large commercial and industrial customers who already receive TOU electric service will see these new periods take effect on January 1, 2008.
