The Energy Performance Indicator Tool (EnPI) V5.1.5 is a regression analysis-based tool developed by the U.S. Department of Energy's Advanced Manufacturing Office (AMO). The tool applies to businesses whether in the manufacturing sector, commercial buildings, federal agencies, data centers, or beyond.
Proposed large-scale electric generation and storage projects must apply for interconnection to the bulk power system via interconnection queues. While many projects that apply for interconnection are not subsequently built, data from these queues nonetheless provide a general indicator for mid-term trends in developer interest.
