Mining Electricity Tariff Checklist addresses cost components beyond a simple energy rate by concentrating on three concrete elements: demand charges, time-of-use pricing and taxes and fixed fees.
Energy analysis begins at the meter boundary. Miner power, ventilation, pumps, transformers and supporting equipment may belong in different measurements, so define the facility boundary before comparing results.
Demand Charges
Define demand charges before comparing it with time-of-use pricing. Identify the unit or rule behind demand charges, capture a dated value where one exists, and state whether the value is measured, calculated or supplied by another party. That distinction determines how confidently demand charges can support the article’s conclusion.
- Evidence: a dated record for demand charges.
- Cross-check: compare it with time-of-use pricing.
- Review trigger: repeat the check after a material change affecting demand charges.
Time-of-use Pricing
The role of time-of-use pricing is best understood through a controlled comparison. Hold unrelated inputs constant, change one relevant condition and observe the response. Then check whether taxes and fixed fees moved in the expected direction. A mismatch is a prompt to inspect the model, not to hide the data.
- Evidence: a dated record for time-of-use pricing.
- Cross-check: compare it with taxes and fixed fees.
- Review trigger: repeat the check after a material change affecting time-of-use pricing.
Taxes And Fixed Fees
Normalize taxes and fixed fees before using it in a table or calculation. Convert units, align the time period and retain the original value. If demand charges comes from a different source, document that source separately so readers can reproduce both sides of the comparison.
- Evidence: a dated record for taxes and fixed fees.
- Cross-check: compare it with demand charges.
- Review trigger: repeat the check after a material change affecting taxes and fixed fees.
Cost components beyond a simple energy rate: evaluation sequence
- Write the exact decision involving demand charges.
- Collect time-of-use pricing using the same observation period.
- Test how the conclusion changes when taxes and fixed fees moves.
- Save the source values, conversions and date of review.
