A recent piece in The Globe and Mail flags “contracted capacity” as a metric investors are now watching closely when they evaluate AI infrastructure companies. That might sound like a Wall Street detail, but it actually points to something every community living near a data center should understand: how much power these facilities promise to use, and to whom.
What “Contracted Capacity” Actually Means
In simple terms, contracted capacity is the amount of electricity (or data center space) a company has formally agreed to buy or build out, often years before it is actually used. For data center operators and the utilities that serve them, these contracts are the backbone of planning. They tell a utility how much new generation or transmission it needs to build. They tell investors whether a company’s growth projections are backed by real commitments or just marketing slides.
Why This Matters Beyond the Trading Floor
When a hyperscale data center signs a long-term power contract, that commitment ripples outward. Utilities use these numbers to justify new power plants, transmission lines, or rate changes that get passed on to everyday customers. Local governments use projected capacity figures to calculate tax breaks and incentive packages. If contracted capacity is inflated, delayed, or quietly renegotiated, the gap between promise and reality can land squarely on ratepayers and taxpayers who had no seat at the table when the deal was struck.
The Accountability Gap
The problem is that contracted capacity numbers are often buried in investor disclosures, utility filings, or corporate earnings calls, not in the public meetings where communities discuss new data center projects. Residents may hear vague promises about “thousands of jobs” or “billions in investment,” without ever seeing the underlying power contracts that drive those numbers. That disconnect is exactly the kind of gap GridWatch the USA exists to track.
What You Can Do
If a data center is proposed or already operating near you, ask your utility commission and local officials for the actual power purchase agreements or interconnection filings tied to the project, not just press release figures. Watch for rate case proceedings where utilities justify grid upgrades using projected data center demand.
