Worked commercial gas cost examples in South Dakota

South Dakota: Build an auditable result instead of a sales story

Start with EIA: natural gas volume, heat content and energy units. The table below links this decision to the represented gas companies in South Dakota. It does not establish service or supplier availability for every account.

Define the counterfactual

Retain what the business would otherwise have paid for the same service months and quantities. Identify whether that is an existing contract, an effective utility supply component or another dated written offer. Do not switch baselines after seeing the result.

Bridge model to invoices

Separate quantity changes from comparable price changes, then reconcile fixed charges, retained delivery and timing corrections. Preserve enrollment confirmation and invoices before presenting an actual outcome. A favorable calculator scenario is only a model.

NorthWestern Energy: the program detail behind this decision

The South Dakota PUC lists distinct commercial sales and transportation schedules by gas company. NorthWestern lists Rate 87 transportation; MidAmerican lists monthly-metered transportation and transportation of customer-owned gas. These require their own qualification and agreements, rather than statewide small-business open enrollment. Sd Current Tariffs.

Apply the evidence to an account file

The case file needs comparable evidence for Sales gas-cost component versus transport, balancing and supplier costs. First establish Actual gas utility, commercial class and applicable transport schedule so the proposed baseline is an available alternative for this account.

Worked case: distinguish a model from an observed result

For a hypothetical 10,000-therm account, $0.80 per therm plus $20 monthly models to $8,240. An alternative at $0.76 plus $60 monthly models to $8,320. That is an $80 increase in the defined supply scope, not a saving. This conclusion is still only a scenario until eligibility, accepted enrollment and actual comparable invoices are established. Keep the same quantity and delivery period in both calculations. Do not present these invented inputs as a local client case or publish them as market rates.

Turn the review into a calculation

Compare constant supply rates and fees. 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.
