Unique Identifier: 240-61713594 Revision: 0 Page: 4 of 71 INTRODUCTION The Transmission Executive Committee (TEXCO) decided to permit Customers to self -build their network connection assets or infrastructure in order to afford them the opportunity to seek efficiencies on cost and/or connection timelines.
