Part of Tribe’s overall plan to diversify their businesses– Decision started the process in
2006
We have the solar resource
The technology started to become economical for our area– Solar costs dropped over 60%
over last 5 years
Grant was critical to the project
Solar Make Sense?
Location of Reservation
Conducted a broad study of solar energy options (2012-2013)
Goalso Identify Lands and Buildings best suited for solar PV projectso Identify if Utility and/or Commercial scale solar is currently viable on
the Reservationo Identify needed conditions for economically viable projects
High level analysis of solar energy opportunity within Reservation boundaries
o Utility Scale – wholesale energy, ground mount, greater than 1MWo Commercial Scale – net metered, roof mount, less than 1MW
Solar photovoltaic (PV) technologyo Low Technology Risko Rapid Price Declineo Widely Deployed
Solar Feasibility Study
Identified most suitable areas for utility scale solar
Utilized site based parameters that impact energy generation, development cost and/or development risk
o Proximity to transmission infrastructureo Proximity to roadso Topography (slope, aspect and flood plains)o Solar resourceo Land Ownershipo Habitat for threatened and/or endangered specieso Others
Utilized GIS data and developed parameter weighted scoring methodology to compare sites (Solar Suitability Score)
Collected data and mapped all Reservation lands
Selected 8 most promising areas
Solar Feasibility Study
GIS Based Solar Suitability
Project Location
Environmental– NEPA - Eligible for a Categorical Exclusion due to early farming and ranching activity
which disturbed the land
Geotech– Utilized an outside contractor and took extra care in this evaluation
Land Lease and Rights of Way– Right to use and access the land (e.g., Trust land)– Complexities
• BIA water ditches• Private property• Utility rights of way and infrastructure• Oil and gas infrastructure
Permitting/Land Access
Discussions included:
Interconnection Agreement• Negotiated with local electric utility • Defines the terms under which the
project can connect to the grid
Power Purchase Agreement• Defines the rates the project will be
paid for the energy provided to the buyer
Utility Project Negotiations
SUIT Buildings that will Benefit from Project
Ten buildings will benefit from the energy produced
(1) SUIT Growth Fund Building(2) SunUte Community Center(3) Animal Shelter (4) Construction Services(5) Construction Services Quonset(6) Water Resources Building (7) Education Area Building 1 (8) Education Area Building 2 (9) Southern Ute Education Center (10) Food Distribution buildings.
These buildings were selected due to their location and ability to offset greater than 15% of fuel usage through electric savings alone. With a ground mount facility and an agreement with LPEA to credit the energy generated to the buildings the Tribe specifies.
Growth Fund Building
