ConnectedSolutions
Program Payment Rate = $225 – $275 per kW-year
Installed (and dispatchable) Capacity = 300 kW
1. Annual incentive
Low-End:
$225 × 300 = $67,500 per year
High-End:
$275 × 300 = $82,500 per year
2. Over a 5-year term (typical ConnectedSolutions performance contract)
Low-End: $337,500
High-End: $412,500
3. Adjust for average performance (if you don’t deliver full rated output during every called event)
Most C&I batteries deliver 60–90 % of rated kW across all events once you include real dispatch behavior and degradation.
So realistic take-home range:
Performance (avg % of rated kW) | $225 rate | $275 rate |
|---|---|---|
60 % | $40,500 / yr | $49,500 / yr |
75 % | $50,625 / yr | $61,875 / yr |
90 % | $60,750 / yr | $74,250 / yr |
That’s roughly $200 k – $370 k total over five years after performance adjustment.
✅ Bottom line:
For a 300 kW C&I battery enrolled in ConnectedSolutions at $225–$275 per kW-year, expect $67 k – $83 k per year gross, or about $0.34 – $0.41 million total over five years before taxes or other savings—then scale by your actual average delivered kW (typically 60–90 % of rated).
Install Cost:
Short version: for a typical ConnectedSolutions-oriented C&I install at 300 kW, a good, defensible turnkey budget (battery + PCS/inverter + BoS + labor + commissioning, excluding incentives/tax effects) is:
2-hour system (≈600 kWh): ~$300k–$500k
3-hour system (≈900 kWh): ~$400k–$650k
Why that range is reasonable (and not just a guess):
Real program example (installed cost): Connecticut’s utility-run Energy Storage Solutions manual includes worked examples with stated installed costs. One is a 250 kW / 675 kWh C&I system at $378,000, i.e. ≈$560/kWh turnkey. Scaling that linearly puts a 300 kW / 600–900 kWh project roughly $336k–$504k at the same $!/kWh—right in the bands above.
NREL cost basis for C&I storage: NREL’s 2024 ATB notes its commercial storage benchmark is built around a ~300 kW, 4-hour BESS with bottom-up component costs, and provides current battery-pack prices by duration (e.g., $215/kWh at 2 h; $199/kWh at 4 h) before BOS, integration and soft costs—consistent with total installed figures landing several hundred $/kWh higher at C&I scale.
Recent cost direction: 2025 Lazard LCOS/market update shows further storage cost declines versus 2024, supporting the lower half of historical C&I turnkey ranges—again aligning with the bands above for today’s buys. (LCOS ≠ capex, but it corroborates directionally lower all-in costs.)
Notes that move you up/down in that range:
Up: tight sites (electrical upgrades, switchgear swaps, trenching), union labor, indoor installs, long-duration (≥3 h), or utility protection/controls extras.
Down: outdoor pad/containerized LFP systems, clean interconnects, shorter duration (≈2 h), multi-unit buys.
If you tell me your target duration (2 h vs 3 h), indoor/outdoor, and whether service upgrades are likely, I can tighten the estimate to a single number (base case + contingency) and then show the net after ConnectedSolutions, ITC, and any state capex buy-downs.
