How to verify gas program and tariff changes in Colorado

Colorado: Trace a change from filing to the affected account

Start with FERC: interstate and intrastate pipeline responsibilities. The table below links this decision to the represented gas companies in Colorado. It does not establish service or supplier availability for every account.

Keep a tariff change record

Record issuing utility, docket or filing reference, affected schedule, approval status, effective date and the first service period affected. Compare the approved sheet with the account’s actual classification.

Treat branding and enrollment separately

A company acquisition or a renamed program does not by itself establish a new price, automatic contract cancellation or eligibility at another utility. Retain customer notices and confirm the legal company and effective service rules.

Xcel Energy / Public Service Company of Colorado: the program detail behind this decision

Public Service Company of Colorado lists separate small and large commercial sales schedules and small and large firm transportation schedules. A transportation tariff is an operating arrangement with its own terms; an Xcel electricity account or another distributor’s gas contract does not qualify the premises. Xcel Co Tariff.

Apply the evidence to an account file

Match a proposed or approved change to CSG or CLG sales compared with the applicable TFS or TFL transportation schedule. Reopen the effective company reference and confirm Transportation agreement, capacity, nominations and imbalance responsibility instead of importing a rule from another service company.

A change log with an explicit implementation gate

Use a row for the company, source URL, document type, schedule, status, approval date, effective date, affected accounts and action owner. A proposed sheet can inform a sensitivity scenario while remaining outside the effective budget. After approval, verify the final sheet rather than assuming the requested amount survived. For an ownership change, attach the service notice and identify any separate legacy rate areas. Retain the prior reference for earlier billing periods so corrections can be checked against the right rules.

Turn the review into a calculation

Plan notice and enrollment milestones. The planner uses your calendar-day inputs and does not send notices or confirm a utility enrollment date.
