Amount of energy stored by the organization during the reporting period.
Organizations should footnote all assumptions used.
This metric is intended to capture actual energy stored, not battery nameplate capacity, generally measured annually as MWh/year or MJ/year. Organizations should footnote whether the storage capacity is targeted at reducing wasted energy from existing generation or at creating storage capacity to enable new generation.

New metric. Energy Stored (PI1435) was developed via the IRIS+ Clean Energy Expert Subgroup.
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).
