Utility costs in acquisitions: what to check after the deal closes
Utility accounts are rarely in the integration plan, yet every acquired site brings its own rate classes, contracts, payment routing and account classifications. Left alone, they produce late fees, default-service pricing and billing errors that run for years.
Why utility accounts fall outside the integration plan
Deal teams work through contracts, payroll, IT systems and insurance. Utilities usually show up only as a cost line in the model. But every utility account is held in the name of a legal entity, is billed to whoever set it up, and carries its own rate class, supply contract and payment history. None of that changes when the deal closes.
Nothing breaks on day one, which is the problem. Power stays on, bills keep arriving somewhere, and the first sign of trouble is often a late fee, a disconnection notice or a supply invoice priced at a default rate months later.
What goes wrong
Bills go to the wrong place
Bills keep going to the old owner's accounts payable address, a closed mailbox or a portal login nobody has. After one large acquisition, more than half of a 103-facility industrial services company's sites were incurring late fees every month. Repeated late payments can also cost an account its good payment history, which some utilities use to decide whether to ask for a deposit.
Supply contracts lapse or never covered the new sites
In deregulated markets, an account with no active supply contract usually falls back to the utility's default or provider-of-last-resort service, which may cost more than a negotiated contract. Sites can also be left out of the buyer's existing contract, or covered by a seller's contract that does not transfer cleanly. Many supply agreements have assignment or change-of-control clauses, volume limits and early-termination terms that only come up when someone reads them.
Your advisor may not cover the new states
Energy brokers and consultants are licensed state by state. An advisor who serves your existing sites well may not be able to buy power or gas for the acquired sites at all.
Inherited billing errors
Acquired accounts were set up for the previous owner's operations and are rarely revisited. Common findings include sites on rate classes that no longer fit their load, optional riders still being paid, stuck or misread demand meters and wrong meter multipliers. In one acquired agribusiness portfolio, two sites on outdated rate classes became 38% and 31% cheaper on average once reclassified, an optional rider worth about $120,000 a year was removed, and a stuck demand meter produced a $97,843 refund.
Classifications that no longer fit
An account set up under a business classification that does not match how the site operates today can carry charges that should not apply. After an acquisition, those classifications often reflect the seller's business rather than yours.
Capacity and transmission tags from someone else's operation
In markets such as PJM, a large part of the electricity bill is set by each site's capacity and transmission tags, which are calculated from the site's load during the prior year's system peak hours. The buyer inherits tags that reflect how the seller ran the site, including lines or shifts that have since changed.
Deposits nobody tracks
The seller may have security deposits on file with the utilities, and the buyer may be asked for new ones when accounts move into its name. Without a list, deposits that should be refunded or credited are simply forgotten.
Reporting gaps
Cost reports and Scope 2 emissions miss the acquired sites until someone adds them. Under the GHG Protocol Corporate Standard, a significant acquisition is a structural change that can require recalculating your base-year emissions, so the sites' history matters as well as their future bills.
The post-close checklist
- Build the account inventory. List every utility account, meter, service address, utility, supplier, rate class and the legal entity on each account, using 12 to 24 months of accounts payable history as well as the seller's list.
- Secure authorization and payment. Update letters of authorization, mailing addresses and payment routing so no bill goes unpaid during the transition, and watch for past-due and disconnection notices.
- Plan account name changes. Ask each utility what a change of account holder triggers, such as a new deposit, a credit check or a reset payment history, before moving accounts to the new entity.
- Find the contracts. Collect every supply contract and record its term, pricing structure, expiration, volume limits, early-termination terms and any assignment or change-of-control clause.
- Audit the inherited accounts. Test every acquired account against its tariff: rate class, riders, meter multipliers, demand, seasonal dates, and capacity and transmission tags.
- Bring sites into procurement. Align contract end dates with the rest of the portfolio and confirm your advisor is licensed in the acquired sites' states.
- Add them to reporting. Add the sites to cost and Scope 1 and 2 reporting, and check whether the acquisition is large enough to require recalculating your emissions base year.
Build the inventory from what was paid, not what was listed
The seller's account list is a starting point. Accounts payable history shows every utility, supplier and account that actually billed the business, including small meters, vacant buildings, lighting accounts and sites that were never on anyone's list.
A practical timeline
| Window | Focus | Why then |
|---|---|---|
| First 30 days | Account inventory, letters of authorization, payment routing, past-due and disconnection notices | Late fees and service risk start with the first missed bill |
| Days 30 to 90 | Supply contracts, deposits, account name changes, bill audit | Contracts need the inventory first; audits recover more the sooner they start |
| Days 90 to 180 | Procurement alignment, capacity and transmission tags, reporting baseline | Contract end dates and tags can be planned once the accounts are under control |
Why the audit should start early
Refunds for past overbilling are usually limited by state rules and utility tariffs to a set look-back period, so every month of delay can put older overcharges out of reach. Errors found early also stop costing money sooner. In the agribusiness engagement, an audit that followed a 2018 acquisition found five issues across three states: $117,412 in refunds and about $120,000 a year in ongoing savings.
Who should own it
Utility integration crosses finance, accounts payable, operations and, increasingly, sustainability. It goes best with one owner who holds the account inventory and a single place where every account, contract and bill is tracked. With Discovery, once the authorization letter is signed and the TaraBase account exists, new facilities are generally added by email, and they flow into bill pay, procurement, auditing and reporting together.
