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.
Purchasing renewable energy is a means decarbonization, but renewable energy projects are not all equal when it comes to cutting carbon. Locational Marginal Emissions (LMEs) measure carbon emission avoided by renewable energy projects at the most granular spatial level: the electrical node where energy is injected into the grid.
