We have studied and evaluated All iterations of solar energy including CST,CSP,PV and CPV as key elements of our design. In many areas solar energy is now a viable first tier option and we are actively including it in our IGLB source pool A significant benefit of the Altresco Integrated IGLB configuration is the ability to integrate new generation and balancing loads as warranted. We are excited about the concept of Zero Carbon IGLB centers. At this time, however we are equally committed to low cost reliable electricity. Solar Energy may, or may not be one or more of the renewable and non depleting options considered in our IGLB solutions. The ability to use both is now reaching as much as 100% penetration in several configurations.
