Questions for a Castle Rock commercial gas review

Can every Castle Rock business change gas suppliers?

No citywide eligibility conclusion follows from a community listing. The applicable Colorado utility tariff, commercial class and accepted supplier or transportation arrangement determine the account’s options. Municipal, cooperative and investor-owned accounts can follow different rules.

Does this guide quote a current business gas rate?

No. The primary references explain service and program structure. Obtain an effective tariff and a written offer for the same usage, delivery months and cost scope. This guide does not present a public average as a price available to your business.
