Methodology &
Transparency

EPI Fair Value™ and EPI Curve Intelligence™ are built on a structured, documented analytical process. This page explains how assessments are derived, how the methodology is maintained, and what the outputs are — and are not — designed to do.

EPI Fair Value™EPI Curve Intelligence™EPI Daily Intelligence

EPI Fair Value™ is a proprietary analytical assessment of where the market should be trading, given current physical fundamentals and market conditions. It is not a price forecast and does not predict future market levels.

The distinction matters: a fair value assessment tells you whether today's price is justified given observable supply, demand and risk conditions — a forecast attempts to tell you where the price will be tomorrow. EPI does the former, not the latter.

The output is a structured view of market value, expressed as a range and a central estimate, updated each trading day. It is designed to inform procurement decisions, not to replace professional judgement.
