When calculating the utility rate for electricity and natural gas, it's important to ensure that the units are in line with the cove.tool defaults. In order to do this, we need to look at the utility bill and convert the units to $/kWh.


Electricity

Most electricity bills are already in kWh. If not, consult with your engineer/utility provider in order to convert to $/kWh. As a result, no unit conversion is required. One thing to look at in detail is the additional fees that are common for electricity billing. An example of possible charges is provided below that shows some of the fees that may be found on an electric bill for a small general service structure.

It is critical that these values are summed in order to avoid 'surprise' charges and fees that might not have been accounted for in the top line of billing. Also, be sure to check your local, state, and federal taxes and take those into account for the grand total.


Natural Gas

There are two main ways to measure the cost of natural gas: by the cubic foot in thousands or hundreds (MCF and CCF respectively) and by therm. Firstly, identify which unit of measure your particular service provider bills you in, then use the table below to convert to $/kWh which you can then use in cove.tool app.

Unit Given

conversion factor to $/kWh

$/US therm

÷ 29.3001

$/CCF

÷ 30.3842

$/MCF

÷ 303.842

For example, if your utility company bills you $0.074 per therm used, you would use the below method to convert it to a usable input.

$0.074/therm ÷ 29.3001 = $0.02526/kWh

You can then use 0.02526 as the input value for the Natural Gas Utility Rate in the cove.tool baseline energy calculation.
