Texas-based New Era Energy & Digital has announced plans to construct a colossal, "hyperscale" data center complex in Lea County, New Mexico, a region already at the heart of the Permian Basin’s oil and gas industry. This ambitious development, intended for intensive AI processing, is projected to be so vast that it will necessitate its own dedicated power generation, comprising both nuclear and natural gas plants with a combined capacity of approximately 7 gigawatts. To put this scale into perspective, it would be equivalent to placing the West’s two largest power plants, the Palo Verde nuclear facility and the Gila River natural gas plant near Phoenix, directly atop one another, with an additional 800 megawatts of capacity. Such an energy output could theoretically power more than 5.3 million homes, though its primary purpose will be to fuel the insatiable demands of digital activities, including movie streaming, social media, and particularly artificial intelligence computations.

While the sheer magnitude of this proposal might suggest significant public attention, it has garnered surprisingly little mainstream news coverage. This lack of widespread reporting is not indicative of any deliberate secrecy, but rather a reflection of how common such large-scale data center announcements have become, diminishing the novelty of each individual declaration. Although New Era’s proposed server farm and similar projects are still in their nascent stages and face significant hurdles before becoming operational, their potential cumulative impact is undeniable. If even a fraction of these proposals come to fruition, they stand to fundamentally transform the West’s electrical grid, its physical landscapes, and its economic structures, mirroring the profound changes brought about by the post-World War II "Big Buildup," which saw the proliferation of massive coal and hydroelectric facilities across the region to power burgeoning urban centers.

Indeed, this transformative shift is already well underway. A recent report from the nonprofit organization NEXT 10 and the University of California, Riverside, revealed that in 2023, data centers in California consumed an estimated 10.82 terawatt-hours of electricity – enough to power roughly one million U.S. households. This substantial energy consumption resulted in approximately 2.4 million tons of carbon emissions, even within California’s comparatively clean energy framework; on grids more reliant on fossil fuels, these emissions would be significantly higher. Furthermore, these facilities directly and indirectly utilized an estimated 13.2 billion gallons of water for cooling and electricity generation purposes. In Silicon Valley specifically, over 50 data centers accounted for roughly 60% of one electricity provider’s total demand, compelling the utility to increase customer rates to fund the necessary upgrades to its transmission infrastructure, substations, and new battery energy storage systems required to meet these demands.

These power-hungry facilities are increasingly being established not just in traditional tech hubs, but also in cities and towns far removed from the original Silicon Valley epicenter. In the Phoenix metropolitan area alone, more than 100 data centers, often resembling large industrial warehouses packed with rows of computer servers, have already been erected within business parks. Projections indicate that planned new developments could escalate Arizona’s overall power demand by as much as 300% above current levels, according to utility estimates. In response to this burgeoning demand, Arizona Public Service recently announced its intention to continue operating the Four Corners Power Plant, a coal-fired facility, beyond its originally scheduled retirement date of 2031.

The Western power grid, while interconnected, is managed by 38 distinct balancing authorities, or grid operators. Projections suggest that nearly all of these authorities will experience an increase in data center-driven electricity demand over the next decade. However, many are currently ill-equipped to meet this escalating need. The North American Electricity Reliability Corp. has issued warnings regarding the growing risk of winter power outages in parts of the West, directly attributing this heightened risk to the surge in data center power consumption. Consequently, many of the largest data center operations are likely to pursue self-generation of power, while utilities will face immense pressure to rapidly expand generating capacity and associated infrastructure to serve on-grid facilities. The substantial costs associated with this new infrastructure development will ultimately be passed on to the utilities’ ratepayers.

The question of how this immense required power will be generated is complex and multifaceted. It is becoming increasingly clear that utilities and developers cannot solely rely on solar and wind power to satisfy the projected demand. In response, utilities are already formulating strategies to extend the operational life of existing coal power plants beyond their planned retirement dates, alongside plans for constructing new natural gas plants and even nuclear reactors. Notably, major technology companies like Google, Switch, Amazon, OpenAI, and Meta are exploring the possibility of powering their proposed facilities with the next generation of small, modular, and advanced nuclear reactors, provided these technologies can be developed and deployed successfully.

The environmental ramifications of these unfolding developments are significant and varied. The combustion of fossil fuels directly contributes to climate change and air pollution, while the extraction processes for oil, gas, and coal can severely damage landscapes. Large-scale solar and wind farms, while renewable, can impact wildlife habitats and often necessitate the construction of hundreds of miles of new transmission lines to transport electricity. Nuclear power presents its own unique challenges, including safety concerns, the persistent issue of radioactive waste management, and the environmental risks associated with uranium mining and milling. Even data centers powered entirely by solar energy and batteries represent a diversion of resources that could otherwise be used to displace fossil fuel consumption on the grid. Furthermore, unless equipped with advanced closed-loop air-cooling systems, many data centers continue to consume substantial amounts of water for cooling, often drawing from municipal drinking water supplies.

Prometheus Hyperscale, a company based in Wyoming, has garnered attention for its ambitious proposals to develop "sustainable" data centers. These plans include dedicated clean energy generation, water recycling systems, and efficient cooling technologies designed to leverage the cold climate of the Northern Rockies. The company has even suggested utilizing waste heat from servers for agricultural purposes, such as warming greenhouses and supporting shrimp-farming operations, and has alluded to the potential use of nuclear micro-reactors for supplementary power. However, the practical implementation of these sustainable aspirations has faced scrutiny. Initially, the facility is slated to operate on natural gas, with Prometheus planning to offset carbon emissions by investing in carbon capture and sequestration efforts from biofuel plants in Nebraska, a strategy that relies on third-party mitigation.

Resistance to the rapid proliferation of data centers and their substantial energy and water demands is evident across the Western United States. However, the localized nature of these projects, often evaluated on a municipal or county level, can make organized opposition feel like a continuous uphill battle. In one instance near Tucson, Arizona, residents successfully opposed a city plan to annex a proposed data center, which would have granted it access to treated wastewater for cooling. In response, the developers relocated the project to county jurisdiction and shifted to an air-cooling system, which conserves water but significantly increases energy consumption. Further opposition prompted the firm to commit to investing in renewable energy sufficient to offset its entire electricity usage on the Tucson Electric Power grid.

Contributing to the challenges faced by opposition groups is the fact that many local governments and utility companies actively welcome data center development. These facilities can provide a much-needed influx of jobs and tax revenue to economically struggling areas, provided they are not granted broad tax exemptions. Simultaneously, utilities are eager to expand their customer base and increase revenue, which can help finance the necessary infrastructure upgrades. NV Energy executive Jeff Brigger expressed enthusiasm for serving the projected data center load in Nevada, highlighting the utility’s readiness to meet this growing demand.

While much of the opposition to data centers is rooted in their environmental impacts and potential effects on utility rates and local communities, concerns also extend to the very nature of artificial intelligence. The allocation of significant water and energy resources for endeavors such as AI-generated essays, answering trivial questions, or creating digital art can seem disproportionate when contrasted with essential uses like food production. While AI undeniably holds immense potential for positive applications, including medical diagnostics and accelerating scientific discovery, questions arise about its current resource-intensive trajectory. Before AI fundamentally reshapes the world, its proponents and developers are being challenged to address its own substantial energy and water footprint, seeking more efficient operational methodologies.
