Furthermore, COGEH provides a standard that other groups such as governments, transmission companies, energy purchasers and financial users, just to name a few, can use in their business models. The current edition (COGEH – Consolidated Third Edition – (Online) – December 2018) is an effort to address the inconsistencies, and to consolidate and restructure the materials to reduce redundancies. Figure 5, taken from COGEH (Section 1.3.6), illustrates on a high level the resource classification system and project maturity sub-class. The definitions for the pertinent classifications (as per COGEH) for the purposes of this report are detailed on the following pages. Figure 5 presents a modified version of Figure 6 where suggested minimum thresholds are included for the sub-classes.
