What is Dinosolar?

The Dinosolar Project is a large utility-scale solar project that will generate 440 megawatts (MW) of electricity and an adjacent 440 MW battery energy storage system (BESS). This will produce the equivalent of powering approximately 115,600 Wyoming homes per year.

Dinosolar will be comprised of a 120 megawatt (MW) commercial solar photovoltaic (PV) power generation facility interconnecting at the Casper North Substation and a 320 MW solar PV facility interconnecting at the Bar Nunn substation. The combined, 440-MW project is located on a portion of 3,591 acres of leased private land just north of Casper and a mile west of Bar Nunn in Natrona County, Wyoming.

How will the power be transmitted?

The solar panels will be connected to each other and to an on-site substation with underground lines. The Project would interconnect with Rocky Mountain Power’s regional transmission system at the 115 kV Bar Nunn substation, located on the east side of the project area, and the 230 kV Casper North Substation on the southeast side of the project area.

Where will the power go?

The power will go onto the Rocky Mountain Power grid. It can directly interconnect to this system without reducing the demand for power from other energy sources.

How will Dinosolar benefit our community?

The Project will generate $8.1 million in property tax revenue during the first year of full operations, which will support local services like schools, roads, police, fire protection, and other essential government services. During the 35-year life of the project, $128.6 million will be generated in property tax. Taxable purchases for the Project will generate an additional $35.2 million in sales and use taxes.

Hundreds of skilled individuals will be involved in the construction of Dinosolar and local labor and materials will be tapped. When possible, local construction labor will be used, but a number of workers will need to temporarily relocate to existing motels, RV parks and other short-term housing in Bar Nunn, Casper, and other nearby towns. Non-local workers will generate economic benefits for local communities as they dine in local restaurants, patronize local businesses, such as gas stations and grocery stores, and pay local sales and lodging taxes. $17 million is estimated from projected retail and lodging expenditures by non-local construction workers.

The Dinosolar project team will provide many of its own services within the project area during construction, including road improvement and maintenance, security, dust and weed suppression, traffic control, and others.

The addition of a solar project creates an opportunity for industries looking to procure renewable energy for their operations to locate in the area and bring full-time and long-lasting jobs to the community.
