Data Center Developer Agreements: Accounting Questions That Need Answers Now
Russ Hissom, CPA
A 1,400-megawatt data center just came online in your service territory. The developer signed a 15-year supply agreement, put up a security deposit, and agreed to a minimum bill. Your CFO calls it a win.
Maybe. But before the ink was dry, someone in your accounting department should have been asking a much more difficult set of questions.
Data center load agreements are generating a new class of accounting and finance challenges. A forward-looking approach to these agreements is required to protect existing customers from paying for stranded costs if the data center franchise isn’t renewed or if the developer exits the system before the contract ends.
The New Reality: Load Agreements with Performance Requirements
Across the country, utilities are scrambling to establish terms for hyperscale data centers—facilities that can draw 100 to 1,400 megawatts around the clock with zero tolerance for outages.
Regulators in Colorado, Michigan, and elsewhere have already ordered utilities to build specific protections into these agreements. Common terms now include:
- Upfront interconnection fees
- 15-year minimum terms
- Take-or-pay minimum monthly bills
- Substantial security deposits and early-exit fees
The push is understandable: utilities need certainty. If a data center uses far less power than anticipated, other ratepayers shouldn’t be left holding the bag for infrastructure built specifically for that load. Structuring the deal is only the first hurdle. Accounting for it is the second.
Four Accounting Questions Your Team Should Be Asking
How do you capitalize infrastructure built for a specific large-load customer?
When you build a substation or extend a distribution line to serve a data center, those costs flow into Construction Work in Progress (CWIP) and eventually into rate base. This feels standard—until you realize this infrastructure serves a single customer with a fixed 15-year agreement, not a perpetual franchise obligation.
The critical question: does a portion of these assets represent customer-specific investment that should be depreciated over the contract life rather than the physical life of the asset? The answer matters for depreciation, rate base treatment, and what happens to those assets if the customer leaves.
What is the impact of security deposits and upfront fees?
If a developer pays upfront interconnection fees or Contributions in Aid of Construction (CIAC), the accounting treatment is rarely “set it and forget it.”
- Liability vs. Revenue: If the fee is refundable, it’s a liability. If it’s earned over time, it’s deferred revenue.
- GASB Implications: If your utility follows GASB rules, consider implementing GASB 62 regulatory accounting to offset depreciation expense with the contributed capital.
The finance team must be involved in contract negotiations early—not reviewing the signed contract after the fact.
Is there stranded cost exposure?
Michigan regulators recently made this explicit: the utility is responsible for any costs it cannot recover from the developer if the facility underperforms or exits.
Modeling these impacts should be an integral part of the negotiation process. Developing forecasted balance sheets over the life of the contract will provide a clear indication of future rate impacts if that load disappears—and those numbers become part of the negotiation itself.
Can regulatory accounting smooth the impact?
Utilities operating under ASC 980 or GASB 62 have a powerful tool: the ability to recognize regulatory assets and liabilities to match the timing of cost recognition with recovery in customer rates.
If a board or commission has ordered cost-protection mechanisms, that signal affects what goes on your balance sheet today. But that protection is only as strong as your documentation. Regulatory accounting doesn’t change the nature of the transaction—it changes the timing to ensure you aren’t hit with massive income statement volatility when a data center exits or underperforms.
Action This Week
If your utility is negotiating a large-load agreement, pull the draft and walk through these four questions with your accounting team before the deal closes. The terms negotiated today will determine your accounting treatment—and your ratepayer protections—for the next 15 years.
Build a simple scenario model: what does the balance sheet look like if the customer uses only 50% of the contracted load? What if they exit in year five? Having those numbers in front of you isn’t pessimism—it’s exactly the analysis your board and auditors will eventually ask for.
