Partner with DMB on 40 − 50 acre solar technology demonstration park
− DMB would own site
− Solar companies would lease location
− SRP would purchase energy and RECs
Targeting 3 − 4 projects, 1 MW each
Select new solar technologies past R&D stage, but not yet demonstrated at MW scale in US
Discussions with numerous solar companies
