Energy Management

Monitoring the use of electricity, natural gas, propane and water is an important part of being good stewards of the environment and taxpayer dollars. The fiscal year 2021 (FY21) energy management program report provides an annual overview of both cost and consumption in county government facilities (not including Chesterfield County Public Schools) as well as an overview of programs and efforts related to energy efficiency and management.

Through several departments, county government maintains approximately four hundred facilities for various purposes, totaling over 2 million square feet. These facilities utilize nearly 720 utility accounts for electricity, natural gas, propane, wastewater and water. Many facilities have 24/7/365 uses such as the jail, Juvenile Detention Home, fire stations and Utilities’ pump stations.

Expenditures

In FY21, the county government spent about $4.6 million dollars on utilities, which is a 2% decrease from fiscal year 2020 (FY20). The only increase was in natural gas, as there were several new gas accounts created in FY21 and several existing accounts with increased use. A categorical breakdown of costs by commodity is as follows:

CommodityFY19FY20FY21FY20-FY21 Percent Change
Electricity$4,073,627$3,901,238$3,745,348-4.0%
Natural Gas$407,685$339,028$438,13529.2%
Propane$21,228$13,311$12,365-7.1%
Water$415,771$424,623$387,750-8.7%
Total$4,918,311$4,678,200$4,583,598-2.0%


Consumption

A decrease in commodity use was also seen in FY21 compared to FY20, except, again, for natural gas. A categorical breakdown of costs by commodity is as follows:

CommodityFY19FY20FY21FY20-FY21 Percent Change
Electricity (kWh)38,031,35135,542,97235,029,266-1.4%

FY21 Success Stories

Bailey Bridge Middle School
$27,345 savings for billing recovery and decreased contracted demand. After discovery of a Dominion contract error regarding the transformer size, Dominion refunded 50 months of facility charges and issued a corrected agreement with a decreased contract demand.

County Administration Building Transformer Replacement
$4,700 in avoided costs for transformer rightsizing as part of a transformer replacement.

Happy Hill Water Station
$36,800 savings for decreased contract demand and billing recovery. Recovered contract dollar minimum charges which were incorrectly assessed by Dominion and implemented decreased demand after equipment failure and replacement that caused a demand spike.

Proctor’s Creek Wastewater Treatment Plant
$266,000 savings for rate changes and avoided costs. Reconfiguration of the electrical feeds allowed for a more advantageous rate schedule to be used.

Solar Power Sites in Chesterfield

Chesterfield County Government and Chesterfield County Public Schools (CCPS) have partnered with Sun Tribe Solar to bring solar power to Chesterfield facilities via a solar power purchase agreement (PPA). In addition to clean, renewable energy, the county and CCPS will achieve ongoing cost savings, primarily through securing long-term electric rate stability. PPAs require no capital investment and Sun Tribe owns, operates and maintains the equipment.

Sixteen county and school facilities have been selected as viable candidates. Factors such as roof age and size as well as orientation are key considerations for selection. The county anticipates actual panel installation beginning in late spring 2022. Moving forward, all new construction facilities and buildings receiving new roofs will be evaluated for viability. Panel electric production for each facility will be monitored electronically and Chesterfield looks forward to the valuable educational and learning possibilities this will provide for its students.
