SEMCO Energy Gas Company Data Access Guide
SEMCO Energy Gas Company is a regulated natural gas distribution utility serving about 302,000 customers across Michigan under Michigan Public Service Commission (MPSC) oversight. Billing and monthly therm consumption are accessible through the My Account portal, but SEMCO uses AMR (not interval-capable smart meters) and has not yet implemented Green Button, so granular interval data and developer APIs are unavailable. Michigan's Gas Customer Choice program lets commercial and industrial customers buy gas commodity from an alternative supplier while SEMCO delivers.

Rate Schedules & Tariff Analysis
SEMCO's general-service rates use a declining-block structure across customer size: as accounts move from GS-1 to GS-3 the fixed monthly Customer Charge and MRP/IRIP recovery rise, while the per-therm Distribution Charge falls. The Cost of Gas (commodity) component carries no SEMCO markup and is the only piece a Gas Customer Choice supplier can compete on. Energy Waste Reduction surcharges apply to usage at or below 90 therms for general-service customers.

SEMCO Energy Gas Company Data Access FAQ
Can my facility get 15-minute or hourly interval gas data from SEMCO?▾
No. SEMCO uses AMR (Automated Meter Reading) metering, which produces monthly reads only. Interval data (15-minute, 30-minute, hourly) is not available to any customer class. The most granular data is monthly therm consumption, exportable as CSV from My Account.
Does SEMCO support Green Button or a data API for our energy software?▾
Not currently. SEMCO has not implemented Green Button Download My Data or Connect My Data, and there is no public developer API. Aggregators can only obtain data through manual export with written customer authorization. Monitor MPSC Case U-20959 for future Green Button implementation.
How does an energy consultant get our SEMCO usage data?▾
Provide written authorization naming the consultant and company, then have them contact SEMCO at 1-800-624-2019 or customer.service@semcoenergy.com with your account number and service address. SEMCO verifies the authorization and emails 12-24 months of billing/consumption, typically within 3-5 business days.
Can our business buy gas from a different supplier and still use SEMCO?▾
Yes. Under Michigan's Gas Customer Choice program, C&I customers can buy the gas commodity from a licensed Alternative Gas Supplier while SEMCO delivers it. Only the Cost of Gas line item is replaced by the supplier's Energy Charge; all delivery and infrastructure charges remain. Compare offers at MI Gas Compare.
Which rate class should our commercial account be on?▾
GS-1, GS-2 and GS-3 trade a higher fixed Customer Charge for a lower per-therm distribution charge as volume rises (GS-3 distribution is $0.11966/therm vs GS-1's $0.19556). Export 12 months of therms from My Account and model the break-even, or ask a SEMCO Key Account Executive.
How can we reduce our SEMCO gas bill?▾
Three levers: shop the Cost of Gas commodity via Customer Choice (the only competitive component), confirm the lowest-cost eligible rate class, and reduce therms through the C&I energy efficiency rebate program (855-298-5387). Largest industrials can also evaluate Large Volume Transportation Service.
