Time Warner Cable (TWC), now Charter Communications, partnered with NREL to perform a REopt^® analysis of the technical and economic potential for solar photovoltaic (PV), wind, and ground-source heat pump systems at 696 TWC facilities.

NREL used its REopt portfolio screening methodology to identify and prioritize 306 sites where adding a renewable energy system would provide cost savings over the project life cycle. Based on the results, if all projects were implemented, TWC would save $37 million over 25 years by meeting 10.5% of its facility energy demand with renewable energy.

Following this initial portfolio analysis, NREL conducted in-depth analysis of project development opportunities at 10 sites and evaluated off-grid solutions that may enable carbon emission reduction and grid independence at select TWC facilities.
