Portfolio Management

3TIER puts recent and future wind performance in context so you understand the risks and implications of variability at potential or existing projects across broad production areas. We enable you to optimize and diversify your portfolio of assets. Our seasonal forecasts also help you structure long-term hedges for energy and capacity transactions.

We use numerical weather prediction models and the best available observations to model weather patterns and climate anomalies that impact wind energy output. Our analysis takes long-term climatology into account (from 10-50 years) and our datasets can be easily integrated into your own internal processes.

Project Forensic Studies

Recognizing and resolving underperformance issues as early as possible helps maximize energy production, optimize operations, and proactively restructure financial and capacity obligations. When performance guarantees are not met and a project is in danger of default, 3TIER can perform a full forensic evaluation of the project. This helps isolate issues related to wind variability so you can identify the systemic cause of underperformance.
