District Energy & Thermal Network Equipment worked example

Downtime Cost at 92% outage exposure included: a worked example in district energy & thermal network equipment

This scenario runs the downtime cost calculation on the strong side: 92% outage exposure included, with every other input held at its documented default. Use it when downtime cost in district energy and thermal network equipment is being put through a district energy and thermal network equipment weighted-cost review.

The inputs for this scenario

  • Affected thermal load or customer-hours: 100 MW-hr, ton-hr, or customer-hr (unchanged)
  • Downtime cost per exposure unit: 45 $ / unit (unchanged)
  • Outage exposure included: 92 % (raised for this scenario; the documented default is 80)
  • Fixed emergency response cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Included variable downtime cost = affected thermal load or customer-hours × downtime cost per exposure unit × outage exposure included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total downtime cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for downtime cost per exposure unit.
  • At this operating point the engine returns 4,140 $ for included variable downtime cost.
  • At this operating point the engine returns 250 $ for fixed emergency response cost.

How this compares with the baseline

  • Against the tool's baseline example, where outage exposure included sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • Use it when scoping an outage's financial impact, building a business case for redundancy, or sizing SLA penalty reserves on a thermal network. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total downtime cost: 4,390 $ (headline result)
  • Downtime cost per exposure unit: 43.9 $ / piece
  • Included variable downtime cost: 4,140 $
  • Fixed emergency response cost: 250 $
