Investments in grid infrastructure to promote efficiency and maximize opportunities and return on wind and solar development are essential. Lessons for the country about grid modernization abound from Texas. For example, CREZ transmission lines cost $6.8 billion to build, but the cost benefits alone substantially outweigh the expense. The renewable energy they enable will save ratepayers $2 billion a year and generate in excess of $5 billion in economic development benefits for Texas -- all while reducing electric sector carbon dioxide emissions by up to 16 percent. CREZ transmission lines are paying for themselves rapidly, and will deliver tens of billions of dollars of net economic and environmental benefits for decades. The success of CREZ lines in Texas should serve as a national model for what can be achieved nationwide.
