Summary
Montana-Dakota Utilities' South Dakota Rate 45 offers interruptible service to data center-type facilities with high density computing, at least 10,000 kW of expected monthly demand and an 85 percent load factor. Customers sign Commission-approved service agreements of three to five years and pay all incremental costs of serving them. The sheets were filed on 15 August 2023 in Docket EL23-020 and apply to service on and after 1 September 2024.
What this does not establish
- The Commission's order in Docket EL23-020 was not opened; the docket page lists a 16 August 2024 order approving a settlement stipulation, which is not confirmed here to address Rate 45.
- Whether any customer takes service under Rate 45 was not checked.
- The rate's availability language ('data center-type facilities') is the utility's own; it does not establish any facility's service arrangement.
Unresolved questions
None recorded.
Relationships
Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.
- No related action is recorded.
