EVM in Energy Projects: Practical Guide
July 30, 2026 · 10 min read · ⚡
Energy projects — solar, wind, hydro, CCGT — face unique EVM challenges: 24–60 month timelines, geographic CAPEX distribution, long-lead equipment, and EPC/FIDIC contracts. Here is how to implement EVM correctly.
Numeric Example: 80 MWp Solar Plant
BAC
$48.0M
PV
$14.4M
EV
$12.8M
AC
$14.1M
CPI
0.91
SPI
0.89
CV
-$1.3M
SV
-$1.6M
EAC
$52.9M
VAC
-$4.9M
3 EV Measurement Methods for Energy Projects
0/100 milestone method
Applies to: Equipment delivery, commissioning
How: EV = 0% until milestone achieved, then 100%
✓ Simple and unambiguous
⚠ No intermediate progress visibility
Weighted milestones
Applies to: EPC contracts with defined gates
How: EV = sum of completed milestone weights
✓ Balanced and widely accepted
⚠ Weight assignment can be subjective
Factory progress reporting
Applies to: Long-lead equipment (transformers, turbines)
How: EV = vendor-certified % of factory completion
✓ Captures value during manufacturing
⚠ Requires vendor transparency
EVM Benchmarks by Energy Type
| Type | CPI ref. | SPI ref. | Risk | Key factor |
|---|---|---|---|---|
| Solar PV | 0.92–1.05 | 0.88–1.02 | Medium | Panel supply chain |
| Wind (onshore) | 0.90–1.03 | 0.85–1.00 | Medium | Turbine transport |
| Wind (offshore) | 0.80–0.98 | 0.75–0.95 | High | Marine weather windows |
| Hydroelectric | 0.85–1.00 | 0.80–0.98 | High | Civil works geology |
| CCGT / Thermal | 0.92–1.05 | 0.90–1.02 | Low-medium | Equipment lead times |
| Transmission line | 0.90–1.02 | 0.88–1.00 | Medium | Right-of-way permits |
