Introduction
A 500 MW data center is not an ordinary commercial development.
When a major AI infrastructure developer approaches a city, the proposal may represent billions of dollars in investment, substantial construction activity, new tax revenue, and opportunities for economic development.
It may also create an electricity demand unlike anything the community has previously experienced.
For mayors, city council members, city managers, economic-development officials, and other local leaders, the challenge is balancing the potential economic benefits with infrastructure commitments that could remain in place for decades.
The right questions therefore go beyond: How many jobs will this create?
Local leaders should also ask: How much power will this project ultimately require? Who will provide it? Who will pay for the infrastructure? What happens if the project expands? And how can the community benefit from the energy investment surrounding it?
Here are the questions every community should consider.
1. How Much Electricity Will the Data Center Ultimately Need?
One of the easiest mistakes is to evaluate a massive data-center proposal based on its initial phase.
AI infrastructure can expand rapidly. A project that begins with a comparatively modest electrical load may eventually require hundreds of megawatts as additional buildings, computing capacity, and supporting infrastructure are added.
Local officials should ask for projections covering:
- Initial operations
- Each planned development phase
- Full buildout
- Expected peak demand
- Potential future expansion
The objective is to understand the project’s long-term electricity footprint, not simply the amount of power needed when the first building opens.
The most important question may be:
What will this project require when it is fully built out?
That answer can affect nearly every other infrastructure decision the community will make.
2. Where Will the Electricity Come From?
When a utility agrees to explore service for a major data center, that does not mean hundreds of megawatts of additional electricity are immediately available.
New demand may require changes throughout the energy system.
Local leaders should ask:
- What existing generation will serve the project?
- Will additional generation be required?
- Are new substations necessary?
- Will transmission lines need to be upgraded or expanded?
- Are local distribution improvements required?
- How long will the infrastructure take to develop?
- Which parties will be responsible for the costs?
These questions should not be interpreted as opposition to data-center development.
They are basic questions about infrastructure planning.
A city should understand what must be built to support a project before committing itself to a development that could shape local infrastructure for decades.
3. Who Will Pay for the New Grid Infrastructure?
This may be one of the most important financial questions a community can ask.
A large new electricity load can require significant investment in generation, transmission, substations, distribution systems, and other grid infrastructure.
Local officials should understand how those costs will be allocated among:
- The data-center developer
- The serving utility
- Existing utility customers
- Future customers
- Public entities
- Other private participants
There is no universal answer.
The allocation will depend on the utility, regulatory structure, location, project economics, and specific development agreements.
But the community should understand the financial structure before decisions are finalized.
A multibillion-dollar data center can deliver substantial economic value. At the same time, supporting that development can require equally significant infrastructure commitments.
Both sides of that equation deserve careful consideration.
4. Could the Project Affect Electricity Costs or Reliability?
Residents and local businesses will naturally want to know whether a massive new electricity customer could affect their own power service.
Local leaders should not have to speculate.
Instead, they should ask the utility to explain the potential effects of the new load on:
- Generation requirements
- Transmission capacity
- Distribution infrastructure
- Peak demand
- Reliability planning
- Capital expenditures
- Electricity rates
The implications may differ depending on whether the community is served by a municipal utility, investor-owned utility, public power agency, or another electricity provider.
What matters most is transparency.
Residents should have a clear understanding of how the project fits into the existing energy system and what infrastructure will be required to accommodate it.
5. What Happens if the Data Center Expands Faster Than Expected?
AI infrastructure is changing quickly.
Computing requirements, facility designs, cooling technologies, and deployment strategies can evolve substantially over the life of a project.
That makes future expansion an important issue for communities.
Local officials should ask:
What happens if the data center eventually requires substantially more electricity than currently projected?
What additional generation would be needed?
Would more transmission capacity be required?
Would another substation need to be constructed?
Would the project require additional water or land?
And who would be responsible for those future investments?
Thinking about these questions early can help prevent today’s development agreement from becoming tomorrow’s infrastructure problem.
6. What Does the Community Receive in Return?
Tax revenue and employment are often the first benefits discussed when a major data center is proposed.
Those benefits are important, but they do not have to be the entire conversation.
Communities can also consider opportunities involving:
- Local contracting
- Construction employment
- Workforce development
- Educational partnerships
- Infrastructure improvements
- Community-benefit programs
- Clean-energy investment
- Local business participation
- Grid improvements
- Long-term economic development
The goal should not be to create unrealistic demands.
The goal should be to establish a relationship in which the community hosting the infrastructure can participate in the value created by the investment.
One useful question for local leaders is:
Ten years from now, how will residents and local businesses know that this development strengthened the community?
7. Could the Data Center Help Accelerate Local Energy Investment?
This is a question that is often overlooked.
A major data center creates enormous electricity demand. At the same time, communities frequently contain underutilized properties that could potentially support distributed energy resources.
These may include:
- Warehouse rooftops
- Manufacturing facilities
- Shopping centers
- Office buildings
- Schools
- Municipal facilities
- Parking lots
- Brownfields
- Underutilized commercial property
Depending on local conditions, some of these sites could potentially support solar generation, battery storage, or other distributed-energy technologies.
That does not mean distributed resources can replace the utility-scale generation and transmission required by a 500 MW data center.
They generally cannot.
The more useful question is:
Could the arrival of a major new electricity customer help accelerate energy investment across the broader community?
That shifts the conversation from simply supplying power to one facility toward strengthening the surrounding energy ecosystem.
8. Can Local Businesses and Property Owners Participate?
A major AI project can create an opportunity to expand energy investment beyond the data-center campus.
Consider a community where:
- A warehouse owner installs rooftop solar.
- A shopping center develops solar parking canopies.
- An industrial property adds battery storage.
- A municipality evaluates solar and storage at public facilities.
- Commercial property owners identify additional sites for distributed-energy development.
The actual feasibility of these projects will depend on utility rules, economics, grid conditions, regulations, and site characteristics.
But the concept is important.
Instead of all energy investment occurring within the boundaries of the data-center project, some investment could potentially reach businesses, property owners, and public facilities throughout the community.
That creates a broader opportunity for economic participation.
9. What About Water, Backup Power, and Environmental Impacts?
Electricity is only one part of the infrastructure equation.
Large data centers can also raise questions about water use, cooling systems, backup generation, noise, air quality, land use, construction activity, and emergency response.
Before approving a major project, local officials should understand:
- Expected water consumption
- Cooling technology
- Backup-generation systems
- Air-quality considerations
- Noise impacts
- Construction activity
- Land-use requirements
- Emergency-response needs
- Sustainability commitments
Not every data center has the same environmental profile.
Technology continues to evolve, and project designs can vary significantly.
That is why communities should request project-specific information rather than relying on general assumptions about data centers.
The earlier potential impacts are understood, the more opportunities there are for developers, utilities, and local governments to address them collaboratively.
10. What Is the City’s Long-Term AI Infrastructure Strategy?
Perhaps the biggest mistake a community can make is treating every data center as an isolated development.
One major facility can attract another.
Then another.
Once a region has established fiber connectivity, electrical infrastructure, available land, and an ecosystem of suppliers and service providers, it may become increasingly attractive for additional digital infrastructure.
That means local leaders should ask a larger question:
What happens if our community becomes an AI infrastructure hub?
Planning may need to address:
- Long-term electricity demand
- Generation
- Transmission
- Distribution
- Water resources
- Land use
- Housing
- Workforce development
- Emergency services
- Tax revenue
- Sustainability
- Community benefits
The goal should not simply be deciding whether to approve an individual project.
It should be developing a strategy for managing an entirely new category of infrastructure.
A Different Model: The Community as an Energy Partner
Traditionally, the relationship surrounding a large electricity customer might look something like this:
Utility → Data Center
The utility supplies electricity.
The data center consumes it.
The community hosts the development.
But AI’s growing electricity requirements create an opportunity to consider a broader model:
Utility + Data Center + Community + Local Businesses + Distributed Energy
This is the concept behind the Solar Harmonic Framework™ developed by Solar Harmonics.
The framework explores how communities hosting major new electricity loads could identify distributed-energy opportunities across commercial, industrial, and public properties while coordinating with the larger energy system.
Potential resources could include:
- Distributed solar
- Battery energy storage
- Solar parking canopies
- Commercial and industrial rooftops
- Municipal properties
- Demand flexibility
- Microgrids
- Other distributed-energy resources
These resources are not substitutes for the large-scale generation, transmission, and substation infrastructure required by hyperscale data centers.
Instead, the question is whether they can complement the larger energy system while producing additional local benefits.
Imagine a Different Development Conversation
Consider a hypothetical city evaluating a major AI campus.
The traditional conversation might sound like this:
Developer: We want to build a multibillion-dollar data center.
Utility: We will determine the infrastructure needed to serve the load.
City: What jobs and tax revenue will the project create?
Now add another question:
City: Could this development also help catalyze energy investment throughout our community?
That question changes the conversation.
The city could evaluate municipal rooftops and parking facilities.
Commercial property owners could explore rooftop solar or solar parking canopies.
Industrial businesses could investigate solar and storage.
The utility could identify where distributed resources could provide value to the broader system.
The developer could explore whether supporting local energy initiatives aligns with its sustainability and community objectives.
The conversation is no longer limited to the data-center property.
It begins to consider the energy ecosystem surrounding the project.
From Community Impact to Community Participation
Communities across the country are debating the impacts of artificial intelligence infrastructure.
Those discussions are important.
But there is another question worth asking:
How can communities participate in the economic and energy investment being created to support AI?
That is different from simply asking residents to accept a massive new electricity load.
It creates a shared challenge for developers, utilities, businesses, property owners, policymakers, and residents to address together.
It also creates the possibility that AI infrastructure can become a catalyst for investment beyond the walls of the data center.
Why California Communities Should Pay Attention
California is particularly positioned to explore this model.
The state has extensive experience with distributed solar, battery storage, clean-energy policy, and sophisticated electricity markets. At the same time, communities face ongoing challenges involving electricity costs, grid capacity, infrastructure development, and the rapid growth of electricity demand.
Now the AI economy is adding another major source of demand.
These trends are converging.
California communities can wait until that pressure arrives at their doorstep.
Or they can begin planning for it now.
A proactive approach gives local leaders more opportunity to understand infrastructure requirements, identify potential community benefits, and develop strategies before individual projects become part of a much larger regional buildout.
The 11th Question May Be the Most Important
The ten questions above can help local leaders evaluate an individual data-center proposal.
But there may be an even bigger question:
If AI is going to drive unprecedented investment in electricity infrastructure, how can some of that investment also strengthen the communities where AI infrastructure is built?
There is no single answer.
Utilities will remain essential.
Large-scale generation and transmission will remain necessary.
Every project’s economics, regulatory environment, and grid conditions will be different.
But communities do not have to remain passive participants in the energy transformation created by AI.
They can become active partners in shaping it.
Powering AI. Empowering Communities.
A 500 MW data center can reshape a community’s energy and economic landscape for decades.
The most forward-thinking local governments will look beyond the immediate questions of jobs, tax revenue, and land use. They will examine how the project fits into a broader energy strategy and whether the infrastructure investment can create opportunities for the community beyond the data-center campus.
The Solar Harmonic Framework™ is designed to help explore that possibility by connecting major electricity demand with distributed-energy opportunities across the communities where AI infrastructure is being developed.
