Energy Intervals

A reading tells the team what was observed at a meter. A consumption interval defines the period represented by an energy quantity. Energy Manager reviews the interval’s start and end, unit and meter before changing it from Received to Validated. Cost Analyst uses accepted intervals as the basis for later rate and production comparisons.

This distinction matters when a production run ends near a change of day or when a meter observation arrives late. The period represented by the energy remains the actual operating interval. Reviewing the record later should not move that consumption into the review date. The team needs the original boundaries to compare like periods and explain exceptions.

• Received consumption. Energy Manager opens intervals awaiting review and checks the meter against its site. Meter Operator supplies the observations needed to explain the energy quantity and the reading mode.
• Interval decisions. Energy Manager checks that the end follows the start and that the period does not overlap another interval being counted for the same meter. Accepted intervals become Validated; unusable intervals become Rejected.
• Comparable totals. Cost Analyst and Sustainability Analyst use validated quantities with their units intact. Keep unlike energy units separate until the team has agreed the appropriate conversion outside the basic comparison.

Agree how intervals are prepared from cumulative and interval observations. Identify the person who checks the boundaries and the evidence they need before accepting a quantity. Test how the site timezone affects dates received from a source system. The interval must still describe the operating period when someone reviews it from another location.

Decide how to handle a period that crosses an effective tariff boundary. Cost review needs a defensible quantity for each applicable rate period. Agree the treatment before the first reporting cycle, including how rejected or incomplete intervals remain visible to the people resolving them. A total should identify the scope of accepted consumption that it represents.

For a rehearsal, use an interval covering 06:00 to 10:00 in the site’s agreed timezone. Give the next interval a start of 09:45 and an end of 12:00. Energy Manager compares both periods with the source observations and identifies the overlap from 09:45 to 10:00. Keep the overlapping interval out of accepted consumption while Meter Operator checks the evidence.

Correct the second interval’s boundary and quantity from the observations together. Moving its start to 10:00 while leaving a quantity that includes the earlier period would still overstate consumption. Energy Manager validates the corrected interval and opens Validated Consumption. Cost Analyst then compares it with an allocation for the same meter and period. A shorter production run needs its own comparable consumption basis before the team can explain a quantity difference.

• Interval Review — Compare received, validated and rejected consumption with their start and end boundaries.
• Validated Consumption — Open accepted meter quantities for cost and production analysis.

Rehearse Reading to consumption, then use Consumption to production cost to test the downstream comparison.
