Amount of energy generated and sold to offtaker(s) during the reporting period.
Organizations should footnote the energy type(s) and all assumptions used.
This metric is intended to capture energy generated for commercial sale by the organization. Bulk energy is usually sold under a power purchase agreement with an electricity utility. The buyer or purchaser of this energy is referred to as the offtaker. The unit of measure agreed by International Finance Institutions (IFIs) is GWh. For other Units of Measure, refer to Unit of Measure (PD1602).
Organizations interested in reporting energy production at a product level should report Energy Capacity of Products Sold (PD1504) and/or Energy Capacity of Product (PD2713).
Organizations wishing to report the amount of energy generated for their own use should report Energy Generated for Use: Total (OI9624).
In some contexts, this metric can serve as an indicator of whether the outcome being sought by an investor or organization is occurring (the WHAT dimension of impact). For more on the alignment of IRIS metrics to the five dimensions of impact, see specific guidance document. No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.

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).
