Amount of energy potentially generated over the lifetime of a product based on its planned operation and context.
Organizations should footnote the energy type(s) and all assumptions used to determine the energy capacity.
This metric is intended to capture the energy that could be generated by the product during its lifetime. It most applies to products that will be operated or used by a client of the organization (as opposed to the organization itself). Organizations with oversight of product use beyond the initial sale should consider reporting against Energy Generated for Sale: Total (PI8706).
This metric is intended to capture the lifetime energy capacity of a single product. Organizations interested in reporting the total lifetime energy capacity of all products sold during the reporting period should report Energy Capacity of Products Sold (PD1504).

IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
