Colorado: Measure consumption before attributing savings
Start with DOE FEMP: boiler purchasing, sizing and lifecycle analysis. The table below links this decision to the represented gas companies in Colorado. It does not establish service or supplier availability for every account.
Build the operating baseline
Record actual billing periods, estimated readings, operating hours and occupancy or production. Separate space heating from process and hot-water use where the available data permits. Explain changes before comparing periods.
Reconcile engineering and procurement
Have qualified personnel evaluate controls, equipment and service capacity. Update the contracted volume forecast after a project and review tolerance or minimum-volume terms. Verify program eligibility and preapproval before treating an incentive as funded.
Colorado utility application
| Gas service company | Contract component to revisit after load reduction | Primary reference |
|---|---|---|
| Xcel Energy / Public Service Company of Colorado | Gas-cost adjustment under sales service versus transportation, fuel and agent charges | Official program / tariff |
| Black Hills Energy | Colorado utility gas cost and customer charges versus any qualified transport proposal | Official program / tariff |
| Colorado Springs Utilities | Gas customer, usage, supply and Clean Heat Plan components | Official program / tariff |
| Atmos Energy Colorado | Applicable gas-cost adjustment versus transportation and supplier costs | Official program / tariff |
Colorado Springs Utilities: the program detail behind this decision
Colorado Springs Utilities maintains the municipal gas distribution system and describes a gas-use-based Clean Heat Plan charge supporting reduction programs. That charge and any equipment project belong in a cost review separately from the commodity assumption. Xcel Colorado transportation schedules do not govern a CSU gas meter. Colorado Springs Gas.
Apply the evidence to an account file
After reducing forecast consumption, revisit Gas customer, usage, supply and Clean Heat Plan components. Ask whether the revised operating load changes CSU commercial gas schedule or any conditions associated with CSU service conditions and commercial project program eligibility.
Worked check: fixed charges do not fall with every therm
Assume hypothetical use of 10,000 therms at a constant $0.80 supply price and a $30 monthly supply fee. Modeled supply cost is $8,360. If use falls ten percent to 9,000 therms with the same price and fee, the total becomes $7,560: an $800 reduction, or about 9.57 percent of that supply total. This excludes delivery, taxes and project costs and proves no equipment result. The illustration shows why a percentage therm reduction is not automatically the same percentage dollar reduction.
Turn the review into a calculation
Build a monthly weighted budget. Enter documented assumptions in matching energy units. Keep any charge outside both supply offers separate; the result does not establish eligibility or an available quote.
Read the Colorado utility guide for the wider service-company distinctions. Convert billed gas units using the bill’s heat-content factor when moving from volume to energy.
