Montana: Make the bid specification match the utility

Start with EIA: natural gas customer choice and eligibility. The table below links this decision to the represented gas companies in Montana. It does not establish service or supplier availability for every account.

Require an inclusion schedule

Ask bidders to mark commodity, capacity, balancing, taxes, utility transportation and account fees as included, excluded or variable. An unanswered field is an unresolved cost, not zero.

Compare risk as well as the modeled total

Read the volume measurement period, assignment process, early-exit calculation and renewal mechanism. Request a written calculation for a material overrun or closure rather than relying on a product name such as fixed or flexible.

NorthWestern Energy: the program detail behind this decision

NorthWestern’s Montana gas schedule list distinguishes general gas distribution, general core aggregation, firm transportation and interruptible transportation. Those are different arrangements with separate conditions. Confirm the legal gas operation and both distribution and upstream obligations before treating a commodity quote as a replacement for bundled service. Nwe Mt Rates; Nwe Mt Aggregation.

Apply the evidence to an account file

Give bidders the same specification for Distribution, supply, upstream transportation and any storage or aggregation fees. Ask who is responsible for Applicable operating company, capacity and balancing responsibilities. Do not rank an incomplete answer as the cheapest complete offer.

Worked check: fees can reverse the lower rate

Assume hypothetical annual consumption of 10,000 therms. A costs $0.80 per therm plus $20 monthly: $8,240. B costs $0.76 plus $60 monthly: $8,320. B’s commodity price is lower, but its modeled supply total is $80 higher. Equal cost occurs at 12,000 annual therms under these constant-rate assumptions. These are invented inputs, not available offers, local tariffs or program thresholds. Delivery, tax, exit costs and any excluded components still require a separate review.

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.
