The value of resilience

[Ampster]

I saw this on another forum and thought it was interesting.

Think we can’t place a value on resilience? Think again

A new critical load tiering approach solves the elusive value-of-resilience challenge and facilitates the proliferation of solar-driven microgrids.

The 25% adder is derived by determining the VOR multiplier for each of the three load tiers, as follows:

• Tier 1: 100% resilience — indefinite energy resilience for critical loads — is worth 3 times the average price paid for electricity. Given that the typical facility’s Tier 1 load is about 10% of the total load, applying the 3x VOR Tier 1 multiplier warrants a 20% adder to the electricity bill.
• Tier 2: 80% resilience — energy resilience that is provisioned at least 80% of the time for priority loads — is worth 1.5 times the average price paid for electricity. Given that the typical facility’s Tier 2 load is about 15% of the total load, applying the 1.5x VOR Tier 2 multiplier warrants a 7.5% adder to the electricity bill.
• Tier 3: Although a standard-size Solar Microgrid can provide backup power to Tier 3 loads a substantial percentage of the time, Tier 3 loads are by definition discretionary; therefore, a Tier 3 VOR multiplier is negligible and assumed to be zero.

Tier 1 : 100% uptime, 3x value
Tier 2 : 80% uptime, 1.5x value
Tier 3 : <75% uptime, 1x value
