NEW HAMPSHIRE
SIFT
Improving PP competitiveness by 4.55%
The Challenge
The construction date for a project in New Hampshire was flexible, but the priority was for it to be optimized for the lowest PPA. Two product combinations were evaluated, and the impact of decreasing ITC and PV Tariffs were explored. The site has no nameplate capacity or interconnection limit. A common rule of thumb is to set DC:AC where inverter clipping is 1.0-1.5%.
The Solution
The client used SIFT (Solar Instant Feasibility Tool) to leverage data against assumptions to find the optimal cost and benefit of each variable. In a traditional site feasibility study, the impact of decreasing ITC and PV Tariffs are hard to gauge due to the complexity of variables that needed to be considered—land constraints, topography, mechanical limits, electrical layouts, time of use, and more.
The Result
The client was able to identify the optimal designs that can help deliver maximum value to project pipelines.
ID | Products | MWac | MWp | DC:AC | GCR | Yield | PPA ($/kWh) |
---|---|---|---|---|---|---|---|
C1 | Combo 1: SAT 2019 | 10.50 | 13.15 | 1.252 | 0.47 | 1692 | .065846 |
C2 | Combo 2: GFT 2019 | 13.50 | 17.18 | 1.272 | 0.53 | 1488 | .072432 |
By using SIFT to analyze the PPAs against the changing module prices and ITC values over time, the client developed a deeper understanding of the project. Overall, PPA competitiveness increased by 4.55% and NPV increased by $250k.
