(AECI) to support the 17 electric cooperatives across Arkansas, fellow cooperatives in neighboring states soon heard of our success and wanted an "established business partner" to supply their renewable needs. This led to TPI being an integral part of helping the electric cooperative and public power market as well as commercial customers of all sizes. TPI's footprint has now expanded to cover multiple states totaling over 71 solar sites to date. Not only has our footprint grown, but our service offerings now include electric vehicle charging, battery energy storage systems, and operations & maintenance.
