Payback years

2.7

Annual value

$99,000

Net cost after ITC

$270,000

How the math works

Outage value = hours × loss. Annual value + ongoing revenue. Net = capex × (1 − ITC).

24 × $3,500 + $15k = $99k/yr. $450k × 60% = $270k net. 2.7 yr payback.

How to Use

  1. Enter microgrid capex.
  2. Enter annual outage hours.
  3. Enter loss per outage hour (tenant claims, spoilage, liability).
  4. Enter demand response additional revenue.
  5. Enter battery life years.
  6. Read payback.

Frequently Asked Questions

Microgrid benefits?

Resilience: keeps building running during outages (hours to days). Critical for: hospitals, data centers, grocery (refrigeration), senior living (life safety), hotels (guest experience), multifamily Class A (tenant liability). Components: solar PV + battery + controls + automatic transfer switch + backup generator. Cost: $4,000-15,000/kW of resilient load.

Outage frequency?

US average: 4-10 hours outages annually. Hurricane zones (Gulf, East Coast): 20-100+ hours. Wildfire zones (CA): PSPS (Public Safety Power Shutoff) 40-200+ hours some years. Texas winter storm 2021: 70+ hours for many. Increasing frequency + duration from climate change. Underwriting reliable microgrid ROI requires location-specific outage analysis.

Value during outage?

Multifamily: tenant liability, spoiled food $50-200/unit, evacuation cost. Hotel: lost revenue $200-600/room/day. Hospital: operating continuity priceless. Grocery: $10-50k spoilage per store per outage. Data center: $1000-100k/minute downtime. Office: $50-500/sqft/day productivity loss. On $100M property: 24-hour outage = $50k-500k in losses depending on type.

IRA funding?

48 ITC 30% on battery storage. Energy community bonus 10%. Domestic content bonus 10%. Low-income bonus 10-20%. Total potential: 70% ITC. 179D commercial deduction $0.50-5/sqft. State grants for critical facilities (hospitals, schools, senior living): $50-500k. Dept of Energy climate resilience grants. Insurance premium reduction 5-15% (self-backup reduces claim risk).
