Data center infrastructure is the foundation of the AI and hyperscale boom, and the rush to build is creating some challenges for site developers and infrastructure companies alike. Operators are racing to secure sites, lock in power capacity, and get shovels in the ground before competitors claim the best locations.
But if you rush your site selection process, you open yourself up to operational and financial risk that will come back to bite you in the form of stranded assets, cost overruns, and facilities that can’t scale with you.
In this guide, we’ll walk you through what matters (and what doesn’t) when selecting your data center site. We’ll talk about power availability, infrastructure, regulations, and more, giving you all the info you need to evaluate sites for your build.
Why data center site selection matters for long-term success
Data center site selection is more of an energy infrastructure problem than a real estate problem. The facility itself is just a shell. What matters is whether you can actually deliver reliable power, cooling, and connectivity to the racks inside.
Selecting the right site for your data center is key for a number of reasons. If you pick the wrong site for your build, you might struggle with some of these challenges:
- Wrong power availability: Without the right power availability off the bat you’ll be stuck with 18-24 month delays while you wait for utility buildout, or complete project death if the grid can't expand.
- Permitting difficulties: If you build in an area with substantial data center opposition, your project can be delayed for months. It is critical to connect with local stakeholders in advance and evaluate the permitting landscape.
- Inadequate network: If your site doesn’t have redundant high-speed fiber availability nearby, your schedule will depend on the fiber build-out, which is out of your hands. Selecting sites with nearby fiber or moving early with fiber providers is key.
These are the consequences of getting things wrong. If you want to avoid these challenges and run a profitable data center, you need the right approach. Let’s walk through the main considerations you need to keep in mind during your search.
Power availability and grid capacity
When evaluating power availability, you need to think about more than substation proximity. You need to know the actual MW available rather than the theoretical capacity — if there’s a substation two miles away from your site, that’s great, but not if it’s already running at 95% capacity without plans to expand.
You also need to evaluate the utility’s willingness to build new infrastructure. Some utilities will fast-track new builds, where others will string you along for years "evaluating capacity.” And if your site requires new transmission lines, add 2-5 years to your timeline.
When a utility says they can get you power but doesn’t provide any hard details or deadlines, it’s often code for "we have no plan and no timeline." We've seen this kill fully permitted projects. At Giga, we see you through the whole site build from end to end. We know which utility promises are real and which ones are wishful thinking designed to keep you on the hook while they figure it out.

Network connectivity and latency requirements
Not all data centers need the same connectivity. Hyperscale cloud operations and AI/HPC workloads live in completely different worlds when it comes to network requirements.
For latency-sensitive applications like hyperscale cloud, enterprise hosting, and financial services, location is crucial. You need proximity to major fiber routes and internet exchange points.
For AI and compute-heavy workloads, the equation flips. Latency matters far less than raw power delivery and cooling capacity. This opens up secondary and tertiary markets with better economics, like lower land costs, cheaper power, faster permitting, and utilities actually willing to build infrastructure.
The trap we see repeatedly is operators overpaying for premium metro connectivity they don't actually need. One site might deliver 2ms better latency, but if your workload doesn't require it, you're wasting money on something you don’t really need.
Environmental and natural disaster risk assessment
Another key element of any data center site selection strategy is the environmental risk assessment. Start with FEMA floodplain maps, seismic activity zones, and wildfire risk assessments. If your site is in a 100-year floodplain or sits on a fault line, you're building a ton of unnecessary risk into your project.
Climate is another consideration. Your site’s cooling efficiency will vary 20-30% based on the ambient temperature, meaning a facility in Phoenix burns significantly more energy for cooling than the same facility in Oregon, every single day, forever.
Water availability also matters for traditional cooling systems, so be sure to keep that in mind for drought-prone regions. Extreme weather can also stress infrastructure in ways that shorten your equipment’s lifespan, which can impact uptime and maintenance costs over time.
You can engineer around certain risks, but you can't engineer around geography. Factor these costs into your TCO model from day one, and remember, the cheapest land is rarely the cheapest site to operate over 10+ years.
Regulatory environment and permitting speed
Permitting can be a timeline killer if you don’t plan for it upfront. When you’re investing in a new data center site, you have to navigate several layers of regulations.
- Zoning compliance and variance requirements
- Environmental permits for air quality, water use, and noise levels
- Utility interconnection agreements
- Building permits and inspections
These regulations vary based on location, and those variations can make or break your budget. For example, Virginia’s SB 1046 has strict noise abatement and public notification requirements, and California’s CEQA process adds environmental review layers. In short, what works in one state won’t work in another, so you can’t assume anything without careful research.
Community sentiment is also important to keep in mind. You’ll need to mitigate this by getting stakeholder engagement early. The earlier you can start to build those bridges with the community surrounding your site, the less likely you’ll be delayed due to local pushback.
Cooling infrastructure and water resources
Every MW of IT load needs roughly 1 MW of cooling, which means that if you're planning a 50MW facility, you're actually planning a 100MW power draw. Sometimes, newer operators underestimate this in early site evaluations and end up scrambling to upgrade infrastructure mid-construction.
Traditional transformer cooling systems depend on three factors:
- Proximity to water plants (or the ability to build them on-site).
- Local water availability and cost.
- Water use restrictions that create future policy risk.
As we mentioned earlier in our section on environmental risks, climate drives the decision related to your cooling infrastructure. What works in Oregon doesn't work in Arizona. Ambient temperature, humidity levels, and water availability all factor into which cooling approach makes the most sense for your specific location.
Pro tip: Build cooling capacity for what you need today, plus 30% for tomorrow's density requirements. Rack densities are climbing faster than most projections anticipated, especially with AI workloads, so you’ll want to build some extra capacity in from day one.
Land availability and future expansion capacity
If you’re not planning to scale from day one, you’re leaving opportunity on the table. Today’s 20MW deployment could need 100MW in three years, and if your current site can’t handle that kind of growth, you’ll be dealing with relocation costs that are way higher than any savings you’ll get now buying cheap land.
A few site characteristics to keep in mind related to expansion opportunities:
- Available acreage for phased future buildouts
- Utility capacity for future power additions
- Modular infrastructure design possibilities (in other words, can you add transformers, switchboards, and cooling in stages, or does everything require a full rebuild?)
If you only invest in the land you need right now, when it’s time to expand you might find out the adjacent parcels have been bought by someone else, zoning prohibits further development, or the utility can’t deliver additional power.
Zoning headroom is one of the biggest battles here. Ensure future expansion doesn't require re-permitting battles. Some jurisdictions allow phased expansion under the original permit, whereas others treat each phase as a new project with full regulatory review. Know which scenario you're in before you commit.
Total cost of ownership (TCO) analysis
The real estate cost of your new data center site only represents about 15-20% of the total cost of ownership. If you’re spending all your time obsessing over land prices and lease rates, you’re missing out on the math that will determine whether or not your project actually makes money in the long run.
Some of the major ongoing operational costs you need to keep in mind during site selection:
- Energy rates and rate structures: Demand charges and time-of-use pricing can swing your monthly power bill by 40%, depending on location.
- Property taxes and incentive programs: Some jurisdictions offer data center tax breaks that can change everything.
- Cooling costs: These are largely climate-dependent, as discussed in previous sections.
- Staffing and operational expenses: Local wage rates, benefits, and turnover all vary by market.
- Interconnection and network costs: Carrier access fees and cross-connect charges vary by market.
You’ll also want to consider the cost of the build itself. Equipment delivery logistics to remote sites can add weeks to timelines and thousands to shipping costs. Plus, you’ll need to consider the lead times and associated costs of all the electrical infrastructure you need for your site.
When one company handles transformers, switchboards, and site development, your TCO drops significantly. This cost drop is because you’re eliminating coordination delays, vendor finger-pointing, and the margin stacking that happens when five different companies each take their cut. That’s why, at Giga, we control the full stack, allowing us to help you build reliable, profitable sites more quickly.
Workforce availability and local expertise
Site evaluation should also include an evaluation of the local pool of data center technicians and other key workers you’ll need to keep your site running.
Markets like Northern Virginia and Dallas have deep talent pools because they've been building facilities for years. Emerging markets might offer cheaper land, but if there are only three qualified data center techs within 100 miles, you may want to proceed with caution, because you’re creating a staffing bottleneck for yourself.
Electrical contractor availability and quality also vary by region. You need contractors who understand high-voltage systems, know how to work safely on energized equipment, and can respond quickly when things go wrong. Research training pipelines and technical schools nearby to see whether you'll have access to qualified workers as you scale or whether you’ll be stuck competing with every other facility in the region for the same small talent pool.
Building a data center site selection strategy that actually works
Considering all the factors laid out in this easy-reference guide will set you up for success with your data center site selection strategy. One of the most common traps that kills project momentum is when a site operator optimizes on one factor and ignores the others.
The cheapest power in the country means nothing if you can't get transformers for 18 months. Perfect connectivity doesn't help if your site sits in a floodplain that floods every five years. You need balance, not perfection in one area and failure in three others. The easiest way to avoid making a mistake when selecting your data center site is to work with the right partner.
Most site selection happens in spreadsheets built by people who've never energized a site. At Giga, we do things a little differently.
We are an end-to-end partner, from site specs to final delivery. We build and operate our own facilities and the transformers and switchboards that power them, so we know the ins and outs of site development, infrastructure builds, and more. With Giga, you get one partner, one timeline, and one point of accountability.
