WHITE PAPER: Friends Don’t Let Friends Use 8760s

A new white paper from REsurety, with contributions from Hannon Armstrong, a leading investor in climate solutions, offers an in-depth analysis into how using an “8760” energy model can lead to significant errors in revenue modeling — topping 30% in some high renewable penetration markets.

 

An “8760” (also known as a “typical meteorological year,” or “TMY”) is the expected typical generation for a given wind or solar project for each of the 8,760 hours in a non-leap year. Despite their widespread use in the renewable energy industry, using an 8760 to project financial performance can lead to significant errors in revenue modeling.
