The Minnesota Division of Energy Resources operates the Guaranteed Energy Savings Program for cities to lock in verifiable ongoing energy savings through performance contracting of deep retrofits - including exterior and interior building lighting - without capital appropriations. GESP is most appropriate, as a rule of thumb, for situations including at least one of the following: city utility bills are around $150,000 or more; possible project cost is around $350,000 or more; city population is around 10,000 or more.
Remove and replace existing Metal Halide and High Pressure Sodium wall packs with full cut-off LED wall packs. Performance has caused continued implementation of this LED technology at all City facilities.
Outcome measures/metrics/money saved:
Better color rendering for safety/security and improved efficiency of lighting that runs more than any lighting.
Since 2011, the City has relamped three parking lots at City facilities with Dark Sky compliant LED lighting. Any interim replacements for wall packs and bollard lighting at facilities are Dark Sky compliant LED. The City as a plan for the relamping of exterior lighting at all City facilities with LED beginning in 2019.
a lighting audit was performed by Xcel energy and CCE on all city facilities. Once the audit was completed the city council authorized LED lighting in all city facilities including, the Wyoming library, Wyoming city hall, Wyoming fire department, Wyoming public works and Wyoming police department. All internal and outdoor lighting was replaced at all facilities.
Outcome measures/metrics/money saved:
Total installed costs of all lighting were $ 28,570.12. The city received a $6, 755.00 utility rebate from Xcel energy resulting in a final cost of $21,815.12. With the LED light conversion the city will save an annually amount of $4,982.03.
Coon Rapids singed a Detailed Engineering Study Agreement with McKinstry in 2009 to complete a performance contract totaling over $800,000 for both electric and gas savings due to implemented Facility Improvement Measures in various city projects. Between 2010 and 2012, various projects were completed to achieve utility savings. Part of this included exterior building improvements through higher quality lighting that consumed less energy which decreased annual exterior lighting electrical consumption by 51%. These projects were completed at City Hall, Police Station, three Fire Stations and Public Works.
BRIGHT UPGRADES FOR THE
The whole project included the following upgrades to LED:
6 bridge lights (bulb replacement)
1 city welcome sign light (bulb replacement)
3 outdoor wall packs (fixture replacement)
1 outdoor pole light (fixture replacement)
12 high bay lights in our maintenance shop (fixture replacement)
26 4-foot linear tubes in our maintenance shop (lamp replacement)
1 street light on Main and Walnut (fixture replacement)
The City replaced standard Wall Pack fixtures on park buildings, the Water Plant, and on the Ice Arena with Dark Sky compliant fixtures and LED bulbs. It is common practice to replace old lighting with LED fixtures at municipal buildings, including well houses.
Energy efficient lighting is used as often as possible. Dark-Sky lighting is not required, but generally used on all lights other than streetlights. In In 2015, the city installed two new energy-efficient LED fixtures on the south side of West Metro Fire Station #3.
The city's LED Retrofit Four Year Plan (2013-2016) requires the use of energy efficient,Dark-Sky lighting when relamping or improving exterior lighting of city-owned buildings. Apprroximately 25% has been completed.
All but 3 parks have had their exterior lights replaced with LED Dark-Sky compliant lighting. All community centers have had this done as well. The city is in the process of relighting the rest of their municipal buildings.
