Energy is one of the largest controllable line items in commercial real estate operating expenses. And in our experience, it's the one nobody actually manages.

Most property managers treat the electric bill the way they treat the weather — it shows up, it's expensive, and there's nothing to do about it but pay. That instinct is wrong, and it's costing portfolios real money. More importantly for an asset, it's costing them value.

This is a playbook for property managers, owners, multifamily operators, and REIT asset teams who want to stop overpaying. We'll walk through the NOI math, where commercial real estate portfolios consistently overpay, why your lease structure decides who actually captures the savings, and what disciplined operators do differently.

The NOI Lever Nobody's Pulling

Here's the thing about commercial real estate energy spend that operators outside the industry never quite grasp: a dollar saved on energy isn't worth a dollar. It's worth a lot more.

Energy is an operating expense. Reduce it, and net operating income goes up by the same amount. But the building doesn't trade on NOI — it trades on NOI divided by a cap rate. So every dollar of recurring energy savings gets capitalized into the asset's value.

The math is brutal in its simplicity. Cut $100,000 of annual energy cost at a property trading on a 6% cap rate, and you haven't created $100,000 of value. You've created roughly $1.67 million ($100,000 ÷ 0.06). At a 5% cap, that same $100,000 is worth $2 million.

Read that again. A procurement decision that takes a few weeks of work can move asset value by seven figures. There aren't many line items in a building's P&L where that's true.

And unlike a capital project — a new roof, a chiller replacement, a lobby renovation — energy procurement savings require no capital. You're not spending money to make the building worth more. You're just paying less for the same electrons.

This is why NOI energy savings should be a standing item in every asset management review, not an afterthought handled by whoever opens the mail.

Where Commercial Real Estate Portfolios Overpay

We see the same patterns across nearly every commercial real estate portfolio we review. None of them are exotic. All of them are expensive.

• Default utility supply. In a deregulated market, leaving a building on the utility's default rate — sometimes called "standard offer service" or "basic service" — almost always means overpaying. It's the rate you get for doing nothing, and it's priced accordingly.
• Auto-renewals at a premium. A supply contract that quietly rolls into a month-to-month variable rate after expiration. We've seen these run 30-50% above market. Nobody noticed because the bill kept getting paid.
• Fragmented contracts across the portfolio. Twenty-five buildings, twenty-five separate contracts, twenty-five different expiration dates, signed at twenty-five different points in the market by twenty-five different property managers. No leverage, no coordination, no benchmark.
• Demand charges nobody's watching. On commercial accounts, demand charges — billed on your peak kilowatt draw, not your total usage — frequently make up 30-50% of the electric bill. Most property managers can't tell you what theirs are.
• Meter and billing errors. Wrong rate class, wrong meter multiplier, tax exemptions never applied, common-area meters billed at commercial rates that should be residential. These errors persist for years.

Property management electricity costs aren't high because energy is expensive. They're high because the procurement was never run like procurement.

Common-Area vs. Tenant-Metered Loads

Before you can manage the spend, you have to know what you actually control. In commercial real estate, that line runs between common-area load and tenant-metered load.

Tenant-metered loads are billed directly to the tenant by the utility. The tenant signs the supply contract, the tenant pays the bill, the tenant captures any savings. You don't control that meter — though you can certainly help tenants procure better, which is a tenant-relations win.

Common-area energy is yours. Lobbies, corridors, elevators, parking garages, exterior lighting, central HVAC, pumps, and building systems. In an office building, common-area and base-building HVAC load can be the single largest controllable cost in the entire operating budget. We routinely see common-area energy run anywhere from $80,000 to over $300,000 per building per year, depending on size, vintage, and climate.

This is the load you procure for directly, and it's where the NOI lever lives.

Multifamily is its own animal. Individual units are usually tenant-metered. But the "house meters" — the ones covering hallways, amenity spaces, laundry, leasing offices, pool equipment, exterior and parking lighting, and central systems — are the owner's responsibility. Across a multifamily portfolio, house-meter load is meaningful, recurring, and almost always under-managed. Multifamily energy procurement done right targets exactly these meters, building by building, across the portfolio.

The Lease Structure Question: Who Captures the Savings?

This is the question that determines whether energy procurement helps your NOI or your tenant's wallet. Skip it, and you can do all the work and capture none of the benefit.

It comes down to lease structure.

Under a triple-net (NNN) lease, tenants reimburse operating expenses, including utilities, on a pass-through basis. So if you cut common-area energy cost, the savings flow to the tenants through lower expense reimbursements — not to your NOI. That's not nothing; lower occupancy cost makes your building more competitive and easier to lease and renew. But it doesn't directly lift your bottom line on a stabilized NNN asset.

Under a gross lease (or modified gross), the owner eats the utility cost. Tenants pay flat rent; you pay the bills. Here, every dollar of energy savings drops straight to NOI — and straight to value at your cap rate. This is where the procurement upside is most direct and most dramatic.

Multifamily, with its mix of owner-paid house meters and tenant-paid units, almost always has direct owner savings on the common load regardless of how unit leases are structured.

The practical takeaway: before you launch a procurement effort, know your lease structure for each asset. On gross-lease and multifamily house-meter load, you keep the savings. On NNN, you're improving competitiveness and tenant economics. Both are worth doing — but they're different value cases, and you should walk into the work knowing which one you're making.

Aggregation Across a Fragmented Portfolio

Here's the single biggest missed opportunity in commercial real estate energy: portfolios with leverage that act like they have none.

Take a portfolio of 25 buildings. Individually, each one is a modest account that suppliers price routinely. Collectively, that portfolio represents serious volume — the kind suppliers compete hard for. But when the buildings are scattered across separate contracts with staggered expirations, that collective leverage never gets to the table.

Aggregation fixes it. You group buildings by deregulated market — PJM, ERCOT, NYISO, ISO-NE, and so on — because suppliers price regionally. Then you take the combined load of every building in that market to bid as one book of business.

The pricing difference is real. A standalone building gets a handful of bids at a comfortable supplier margin. A 25-building portfolio bid as an aggregated book gets bid by far more suppliers at a far thinner margin — what we'd call an aggregation discount. Combined with moving off default utility rates, this routinely produces 20-30% supply-cost savings across participating buildings.

Aggregation doesn't mean one contract. Different states, utilities, and entities make that impractical, and you usually don't want cross-guarantees between assets anyway. It means coordinated procurement: one RFP, a common bidder pool, normalized terms, and synchronized timing — with each building still signing its own agreement, at portfolio-level pricing.

The prerequisite is unglamorous but essential: a master inventory of every meter, every contract, every rate, and every expiration date across the portfolio. Most operators have never built this. It's two to three weeks of work, and it's the document that makes everything else possible.

Bill Auditing: Found Money Hiding in Plain Sight

Procurement gets you a better rate going forward. Bill auditing recovers what you've already overpaid.

Utility and supplier billing errors are more common than anyone wants to admit, and on commercial real estate accounts they compound across many meters and many months. The recurring offenders we find:

• Wrong rate class. A common-area or house meter billed on a more expensive commercial schedule when a cheaper applicable rate exists.
• Meter multiplier errors. A transformer or CT ratio entered wrong, multiplying every kilowatt-hour by the wrong factor for years.
• Demand charge miscalculations. Ratchet clauses applied incorrectly, or peak demand mis-measured.
• Missing tax exemptions. Sales tax charged on usage that qualifies for exemption — common on residential-classified multifamily house load.
• Phantom meters. Charges for meters tied to equipment that was removed, or to space that's been vacant for years.

Many of these errors are recoverable retroactively, often going back several years. Across a 25-building portfolio, a thorough bill audit frequently surfaces recoverable refunds plus ongoing corrections — money that was already yours, sitting on the table.

One more reason to audit now: energy benchmarking ordinances. A growing number of cities and states require commercial and multifamily buildings above a square-footage threshold to track and report energy use annually. The compliance process forces you to gather meter-level data anyway. Use that same effort to audit the bills and benchmark your rates against the market while you're already pulling the data.

What Disciplined Operators Do

The operators who get this right don't do anything magical. They just run energy like a managed expense instead of a fixed cost. Specifically:

• They build the inventory. One schedule, every meter, every contract, every expiration, portfolio-wide. Living document, updated as contracts renew.
• They separate the load. Common-area and house meters they control versus tenant-metered load they don't — and they focus procurement effort where the savings flow to them.
• They check the lease. They know, asset by asset, whether savings hit their NOI (gross, multifamily house load) or improve tenant economics (NNN).
• They aggregate. They bid the portfolio as one book by market, not building by building, and capture the aggregation discount.
• They run real RFPs. Multiple suppliers, normalized terms, synchronized timing — not a quick quote from whoever called last.
• They audit the bills. Every meter, every line item, looking for the errors that hide in plain sight, and they recover what's owed.
• They watch demand charges. They know what their peak-demand component costs and they manage it, because on commercial accounts it's often half the bill.
• They manage on a calendar. Renewals tracked in advance, never letting a contract roll to a punitive variable rate.

Our Recommendation

If you manage or own more than a handful of buildings with owner-controlled energy load — gross-lease office, multifamily house meters, mixed-use common areas — you almost certainly have NOI energy savings that aren't being captured. And because those savings get capitalized at your cap rate, the value at stake is far larger than the line item suggests.

Start with the inventory and a benchmark. It's a few weeks of work, it requires no capital, and it usually surfaces enough opportunity — between supply savings, aggregation leverage, and bill-audit recoveries — to justify everything that follows.

The electric bill isn't the weather. It's a number you can manage. And in commercial real estate, managing it is one of the highest-return, lowest-risk moves available to you.
