Electricity has become one of the most important factors in data center development.
A property may have land, fiber, and suitable zoning but still face delays if the electrical system cannot serve the requested load. Developers also need to determine how power will be procured, where renewable energy and battery storage fit, how reliability will be maintained, and how the project will affect its host community.
This FAQ addresses the questions Solar Harmonics hears across:
The answers provide strategic context. Every project still requires site-specific utility, engineering, legal, environmental, and financial analysis.
Data centers use electricity for servers, processors, networking equipment, data storage, cooling, power conversion, lighting, security, and other building systems.
AI workloads can increase demand because they often rely on large numbers of high-performance processors operating in dense configurations. The computing equipment consumes power and produces heat, which must be removed to maintain reliable operation.
They can be. AI training and inference may use higher-density computing equipment and more advanced cooling systems than many conventional enterprise facilities.
Differences may include:
Not every AI facility has the same design or demand profile.
There is no standard figure. A smaller facility may require tens of megawatts, while a large campus may reach hundreds of megawatts at full build-out.
Demand depends on:
A megawatt, or MW, is a measure of power equal to one million watts. Data center capacity requests are often described in megawatts.
Power describes the rate at which electricity is used. Energy describes electricity used over time and is commonly measured in megawatt-hours, or MWh.
Load factor compares average electricity demand with peak demand over a period. Data centers often operate continuously and may have relatively high load factors.
A high load factor matters because the facility may require substantial energy around the clock rather than only during a short daily peak.
A useful forecast should identify:
The forecast should reflect realistic construction and equipment deployment rather than only the maximum conceptual build-out.
A site may be capable of serving the first building but lack a credible path to full campus demand.
Separating the phases helps utilities and developers understand which capacity is available now, what upgrades are needed later, and whether the expansion schedule is realistic.
Not in the same way. Utility load represents electricity expected from the grid. Backup generation is on-site capacity intended to support defined loads when normal service is unavailable.
The two should be reported separately. Installed backup-generator capacity is not automatically the same as the facility’s continuous demand.
Yes. New processors, liquid cooling, and changing customer requirements may allow more computing equipment within the same building.
Developers should consider whether the electrical and mechanical systems, substation, utility service,e and site layout can accommodate higher future density.
Traditional data center energy planning often focuses on one central question:
Where will the electricity come from?
The Solar Harmonics Framework expands that question.
We look at how the data center, power provider, renewable energy resources and surrounding community can work together as part of a more complete energy strategy.
The goal is to help create a path to power that supports the facility while also addressing the concerns that can influence project approval, operating costs and long-term community acceptance.
Every strategy begins with the project's actual needs, including expected load, expansion plans, reliability requirements, sustainability objectives and target energization timeline.
We examine the role of the serving utility, municipal power provider or community choice aggregator and identify the opportunities and constraints surrounding the project.
Solar generation and battery storage can become part of a broader portfolio rather than being treated as stand-alone technologies. Depending on the project, this can include onsite generation, offsite projects, distributed commercial solar and battery energy storage.
Nearby businesses, warehouses, industrial properties and other large energy users may represent additional opportunities for distributed solar and storage. Instead of concentrating every energy investment inside the data center property line, the framework looks for ways the surrounding community can participate.
A well-designed energy strategy can potentially support several objectives at once: Increase renewable energy generation Create opportunities for local businesses and property owners Support broader grid and energy goals Demonstrate tangible community benefits Strengthen relationships with cities and local stakeholders Support the data center's sustainability commitments
The data center doesn't have to be viewed only as a massive new electricity load. It can also become a catalyst for new energy investment in the region where it operates.
Grid capacity is the ability of transmission, substations, transformers, rs and distribution systems to serve electrical demand while meeting reliability and operating requirements.
Capacity is location-specific. Regional generation does not guarantee that power can reach a particular parcel.
No. Proximity is useful, but available capacity depends on:
Only the serving utility and applicable technical studies can establish the site’s power path.
A utility study evaluates how a requested load may connect to and affect the electrical system. Depending on the provider and project, it may identify facilities, upgrades, costs, and schedule considerations.
The exact study process varies by utility, service voltage, and jurisdiction.
Potential improvements include:
Large projects may require several of these elements.
Responsibility depends on utility rules, tariffs, contracts, regulation, and the type of infrastructure involved.
Developers should obtain clear information about customer-funded facilities, refundable contributions, shared-network upgrades, ongoing charges,s and protections if the project changes or is canceled.
Time to power is the period required to deliver the electrical capacity a data center needs to operate.
It may include:
Transformers, switchgear and other electrical equipment can have long procurement schedules. Substation and transmission work may also require design, land, approvals and coordinated utility construction.
A data center building can therefore approach completion before its full electrical capacity is available.
Potentially. A campus may begin with available capacity while larger improvements are completed:
Initial Capacity → First Data Hall → Grid Upgrade → Additional Capacity → Full Campus
Every phase should have an identified capacity source, infrastructure milestone, and expected delivery date.
Sometimes onsite resources may support selected loads or interim strategies, but feasibility depends on fuel, emissions, permits, cost, reliability, and utility requirements.
Onsite generation should not be assumed to eliminate the need for grid service.
A CCA is a California program through which qualifying local governments procure electricity for enrolled residents and businesses in investor-owned utility territory.
No. For CCA customers, the investor-owned utility generally continues transmission, distribution, metering, billing, collection, grid maintenance, and outage response. The CCA generally procures electricity.
The utility responsible for the physical grid evaluates service capacity and required infrastructure. A CCA can plan electricity procurement but cannot create local substation or feeder capacity through an energy contract alone.
The PCIA is intended to prevent remaining utility customers from bearing certain legacy procurement costs associated with customers who depart bundled service.
Its value and methodology can change. A project should include applicable PCIA charges or credits when evaluating total electricity cost.
No. A bill may include CCA generation, utility transmission and distribution, demand charges, PCIA, public-purpose charges, taxes, and other items.
Power delivery is the physical movement of electricity through transmission, substations, and distribution infrastructure to the site.
Power procurement is the commercial arrangement used to purchase energy, capacity, or environmental attributes.
A renewable contract may support sustainability goals without solving a local grid constraint.
A PPA is a contract to purchase electricity or associated products from a generation resource for a defined period.
Terms may address price, quantity, location, renewable attributes, settlement, curtailment, credit, and project-performance risk.
Not necessarily. Many PPAs are financially settled or associated with generation elsewhere on the grid.
The project should accurately describe whether the arrangement provides physical delivery, financial settlement, renewable attributes, or a combination.
Matching compares electricity consumption with renewable generation or purchased renewable attributes.
Annual matching balances totals over a year. Hourly matching attempts to align consumption with carbon-free supply by time and, depending on the program, location. These approaches should not be described as identical.
Some contract components may be fixed or hedged, but total electricity cost can still change because of delivery rates, demand charges, regulatory adjustments, market conditions,s and taxes.
Long-term models should use scenarios.
On-site solar alone will generally not meet the continuous demand of a large AI data center.
The campus may have limited rooftop and parking area relative to its electrical load. Cooling and mechanical equipment can also reduce usable roof space.
Potential locations include:
Every location requires structural, electrical, financial, and interconnection review.
MW describes the solar system’s rated power. MWh describes the energy it produces over time.
A 10 MW solar facility does not produce 10 MW continuously. Production changes with sunlight, weather, season, and system performance.
It may, depending on ownership, contracts, renewable attributes, accounting rules, and the project’s stated target.
Claims should clearly explain what is purchased and how performance is verified.
Possibly, but not automatically. Its value depends on where it connects, when it generates, local load, grid configuration,n and utility treatment.
During early site evaluation—before the property, schedule, and campus design are fully locked in.
The framework connects:
Load Definition → Grid Path → Power Procurement → Solar + Storage → Community Energy → Expansion
It begins with the facility’s actual requirements and then examines opportunities beyond the property boundary.
No. Solar Harmonics provides strategic energy planning focused on grid, procurement, solar, storage, distributed energy, and community opportunities.
Utilities, engineers, EPC contractors, environmental consultants, attorneys, and other specialists remain responsible for their respective work.
The goal is to establish a realistic path between the project’s computing requirements and the infrastructure, procurement, and energy resources needed to support them.
That means understanding:
where power comes from, when it can be delivered, how the campus can expand, where renewable energy and storage fit, and how the project can create measurable local value.
Storage may support:
MW measures charge or discharge power. MWh measures stored energy.
A 100 MW / 400 MWh battery can theoretically discharge at 100 MW for approximately four hours before accounting for operational limits and losses.
Not necessarily. Emergency and standby power systems must meet project-specific reliability, duration, and code requirements.
A battery may support some backup functions, but its usable duration, controls, and reserved state of charge must be sufficient.
Only if the system has enough usable MWh to support the relevant load for the required duration.
For a very large campus, an overnight battery would be a substantial project. The answer cannot be determined from MW capacity alone.
No. It stores electricity produced elsewhere and releases it later. Charging losses mean less energy is delivered than was used to charge it.
Backup generators help support operations when normal grid service is unavailable. They are part of a wider reliability design that may also include redundant utility feeds, uninterruptible power supplies and batteries.
Options may include diesel, natural gas, renewable fuels, fuel cells, batteries, and emerging technologies.
Each has different trade-offs involving runtime, emissions, fuel supply, maturity, permitting, cost, and reliability.
A microgrid coordinates generation, storage, controls, and loads and may allow selected systems to operate independently from the wider grid under defined conditions.
It is an architecture, not a single device.
Power usage effectiveness, or PUE, compares total facility energy with the energy used by computing equipment.
A lower PUE generally indicates less overhead for cooling, power conversion,n and other non-computing systems. PUE does not capture every environmental factor and should be interpreted with operating conditions in mind.
Some workloads may move across time or locations. Batteries, cooling controls, and demand-response strategies may add flexibility.
The actual capability should be defined by:
Latency, security, customer agreements, and reliability may limit participation.
A large campus may influence:
The scale and direction of each effect depend on the project.
It is a structured effort to connect data center development with practical local energy investments.
Potential projects include:
Not necessarily. Some resources may connect physically or contractually to the campus; others may operate independently.
The relationship should be described accurately.
Useful metrics may include:
Commitments should also identify responsibility, deadlines, reporting, and consequences for nonperformance.
No blanket claim is supportable. These resources may create benefits, but electricity demand, infrastructure, water, emissions, noise,e and land-use effects require separate analysis.
