Economics of Riot Platforms’ 1 GW Colorado nuclear mining campus

Nuclear power drives the shift to AI infrastructure

Riot Platforms secures a 22% cost advantage per kWh through its 1 GW Colorado nuclear-powered mining campus. This facility follows Xcel Energy’s October 2026 baseload PPA rate renegotiation. The partnership with Terrestrial Energy focuses on providing reliable baseload power for Riot’s digital infrastructure. This move allows Riot to support power hungry AI and hyperscale data center customers. The Colorado site targets high performance computing workloads that require consistent energy. This specific economic edge separates Riot from competitors relying on volatile grid pricing. The collaboration aims to deploy multiple 390 MW IMSR plants to reach a total of 4 GW of capacity. This scale supports the company’s shift from a Bitcoin mining firm to a power first digital infrastructure company. Since 2024, Riot has discussed pivoting toward AI and high performance computing. The company hired Jonathan Gibbs, a veteran with experience in developing data centers totaling over one gigawatt of capacity, to lead this effort. Riot aims for a total hash rate of 16 EH/s by the end of 2025 and expects to expand its Kentucky operations to 110 MW under existing agreements.

Comparative energy costs in Texas and Colorado

The Colorado nuclear project directly challenges the economic dominance of Texas-based mining operations. Riot operates large facilities in Texas, including the Rockdale site which uses 450 MW of power. In August, Riot earned $31.7 million in energy credits from ERCOT by limiting consumption during a heatwave. This credit amount exceeded the $8.9 million value of the 333 bitcoin the company mined during the same period. The credits were $24.2 million from energy sold back to the grid and $7.4 million in demand response credits. You should note the difference between these Texas demand response credits and the steady baseload provided by Colorado’s nuclear reactors.

Texas electricity rates for residents in the Oncor district are 13 cents per kWh. In a previous report, Riot stated it paid only 2.8 cents per kWh. The Texas market allows for price fluctuations during peak summer months when air conditioning use spikes. Residents in the state paid an average of 16.01 cents per kilowatt-hour in March 2025. Billing complaints involve 48% of cases involving Texas electricity providers.

Advancements in small modular reactor technology

Terrestrial Energy provides the Integral Molten Salt Reactor (IMSR) technology for the Colorado campus. These modular reactors produce 190 MW of capacity per unit. The companies intend to deploy multiple units to reach a total of 4 GW of capacity. This massive scale supports Riot’s goal of building large-scale data centers for hyperscale tenants. The IMSR design places non-nuclear energy conversion systems in a Thermal and Electric Facility remote from regulated nuclear systems. This separation provides a competitive advantage over other small modular reactor developers. The design also allows for hybrid fuel configurations using natural gas to support early operations and improve system resilience. Terrestrial Energy uses standard-assay low enriched uranium (SALEU) for its fuel, which avoids the supply chain challenges associated with high-assay low enriched uranium (HALEU). This fuel choice allows for easier commercial scale deployment. Terrestrial Energy was selected as one of 11 advanced nuclear reactor projects to participate in the US Department of Energy’s Nuclear Reactor Pilot Program. This momentum follows a partnership with Schneider Electric in April 2024. The company targets commissioning its first IMSR power plants in the early 2030s.

Financial risks and infrastructure expansion

Riot faces significant financial pressure while pursuing these nuclear expansions. The company reported $167 million in revenue and a $27.7 million net loss for the first quarter of 2026. It carries a $200 million secured loan facility backed by financial assets. Adding large scale power initiatives increases execution risk if regulatory approvals for nuclear siting or reactor licensing fail. Terrestrial Energy expects to commission its first IMSR power plants in the early 2030s. This timeline creates a long lead time for expected earnings. The transition from pure Bitcoin mining to a power first digital infrastructure company requires substantial capital to support the construction of advanced nuclear reactors and large-scale data centers. Riot’s expansion into Kentucky via the Block Mining acquisition added 60 MW of operational capacity. This deal also introduced new management and geographic complexities. Riot paid $92.5 million for Block Mining, using $18.5 million in cash and $74 million in Riot common stock. The agreement includes a potential for up to $32.5 million in additional earn-out payments through 2025 based on executing power purchase agreements. While the nuclear route offers a path to stable costs, the company must still manage its existing Bitcoin mining footprint in Texas, which includes 1.7 GW of power capacity across two facilities. Will the capital-intensive nature of nuclear deployment stall Riot’s ability to scale its data center platform alongside its Bitcoin mining operations?
