Matzke72-2 5»1 SUBJECT: 1994-95 Winter Season Peak Reduction Strategies / The Light and Power Department has implemented a number of < strategies over the years that attempt to reduce our winter season \ system peak. The cost to serve load that appears only at the time ~ ) of system peak is $64.68 per kW. Some of these programs include f demand and time of day rates for customers with electric heat, ..,< energy audits, highway lighting replacement, Municipal building 1 efficient lighting and electric thermal storage heat, and purchase l of low loss distribution transformers. All of the above programs represent equipment that has been installed and should be working : at the time of system peak, but that the department has no control 1 over. 1 In addition to the above programs, we have developed a number of strategies which require active involvement by department personnel : to be successful. gl. Substation Voltage Reduction. A one per cent reduction in substation voltage results roughly in a one per cent reduction in system load. A two per cent voltage reduction with a system load of 18,000 kW would result in a load reduction of about 360 kW. /2. Emergency Generator Rebate Program. We will probably have 140 kW of load that can be offset by customer owned emergency generators in time for this winter season. 4 3. Street Light Over'ride We have the capability to override the photocontrols on approximately 35 kW of decorative street lights in the downtown area. In addition, the Christmas twinkle lights (14 kW) can be turned off on peak days. 4. Beat the Peak Program. This is a public awareness program i through Channel 8, KRKI, and flyers requesting customers to voluntarily conserve between the hours of 5:00 p.m. and 8:00 p.m. These four programs require that we anticipate the day that the ~ peak might occur and take the appropriate action. The potential savings in purchase power cost can be significant.

The Estes Park Light and Power Department anticipates peak electrical loading conditions tonight. There is ample capacity on our system to serve all of our customers' requirements. However we can avoid a substantial penalty on our wholesale power bill by reducing this peak electrical load during the hours of 5:00 p.m. and 8:00 p.m. tonight. You can help us keep our electric rates low in Estes Park by ; conserving electricity between 5:00 p.m. and 8:00 p.m. Here are i some suggestions: • Do your baking before 5:00 p.m. or after 8:00 p.m. if you 1 have an electric oven. • Do not operate your electric clothes dryer between 5:00 p.m. and 8:00 p.m. • If you have an electric water heater avoid activities that consume a lot of hot water between 5:00 p.m. and 8:·00 p.m. such as showers or running clothes washers or dishwashers. • Do not turn on Christmas lights. We are not asking customers to make sacrifices, only to alter their schedules, when convenient. This is a voluntary program that we hope will benefit all of us.
