Commercial Electricity for Self Storage Facilities in Texas

Energy strategy for Texas self storage

Self storage is the operational opposite of a restaurant: minimal labor, minimal customer interaction, and a cost structure where real estate, debt service, and electricity are the three largest line items. For a climate-controlled facility, electricity is a meaningful share of operating expense. For non-climate facilities, it is smaller but still worth optimizing. Texas self storage has grown fast, with REITs, PE-backed consolidators, and family-owned operators all competing for market share.

This guide covers how self storage electricity load behaves across climate-controlled and non-climate facilities, how multi-facility operators and REITs use portfolio leverage, and how Electric Decisions runs a documented procurement built around the realities of running a storage portfolio.

How self storage facilities use electricity

Self storage load splits into two very different profiles depending on whether the facility is climate-controlled.

Climate-controlled facilities carry an HVAC baseline that runs year-round at scale. A multi-story climate-controlled facility can have HVAC driving the majority of total consumption. Load factor is high because the HVAC runs continuously in Texas heat and is a near-constant load. Summer HVAC load can run meaningfully above winter baseline.

Non-climate (drive-up) facilities have a dramatically different load profile. Lighting (24/7 for security), gate access systems, security cameras, and office HVAC during open hours make up most of the usage. Load factor is lower than climate-controlled facilities because the lighting dominates and operates on a different pattern. The gap between a climate-controlled and a non-climate facility of similar square footage can be substantial.

Mixed facilities (climate-controlled units on part of the site, non-climate on the rest) are increasingly common. The electrical load tracks the climate-controlled portion mostly, with the non-climate adding modest incremental load.

Office and ancillary load includes office HVAC, lighting, boxes-and-moving-supplies retail area, elevators (for multi-story facilities), and sometimes a resident manager apartment. This is modest but constant.

Lot and perimeter lighting runs around the clock at non-climate facilities for security and visibility. LED retrofit opportunities here are among the highest-return capital projects in the industry.

What drives your monthly bill

The number on your self storage electricity bill is not one price. It is a stack of charges.

The energy charge is the per-kWh number suppliers quote. Under a typical fixed-rate contract, this is the only piece that is actually locked.

TDSP delivery charges cover poles, wires, transformers, and metering. Regulated.

Demand charges matter more at climate-controlled facilities because the HVAC system creates measurable peak demand, particularly on Texas summer afternoons. For non-climate facilities, demand is modest.

4CP transmission rarely applies to standalone self storage facilities because few hit the 700 kW threshold. Large multi-story climate-controlled facilities in dense urban markets occasionally cross it, and large portfolios on consolidated metering can.

Regulatory, fees, and taxes cover PUCT assessments, ERCOT fees, gross receipts tax, and sales tax. For a plain-English walk-through of how commercial electricity gets billed, see the commercial electricity pillar guide.

Contract decisions that move the number

Three decisions do most of the work on a self storage electricity contract.

Term length: Most Texas self storage operators land on 24 or 36 month fixed-rate terms. Climate-controlled operators with heavy summer HVAC exposure often benefit from longer terms when the forward curve for summer months is low.

What is actually fixed: A fixed-rate contract often lets delivery charges, 4CP (where applicable), regulatory pass-throughs, and supply-side demand charges float.

Bandwidth: Your contract assumes a usage range. Converting non-climate units to climate-controlled, adding a new building, or expanding the retail office all change usage.

The TDU delivery charges explained guide walks through the delivery side in detail.

REITs, chains, and multi-facility operators have real leverage

The three public self storage REITs and the larger regional operators have procurement at scale, but there are also hundreds of smaller multi-facility operators in Texas who do not run competitive RFPs.

Suppliers price a combined portfolio more aggressively because the volume is easier to hedge. Coordination questions:

Renewal cohorts: Larger portfolios typically stagger renewals across two or three cohorts per year.

TDU zone coverage: Statewide portfolios span multiple utility zones. The Texas Retail Electric Providers directory lists which suppliers actively bid each zone.

Add-a-site language: Operators acquiring new facilities need a clean mechanism for adding meters.

Facility type mixing: Climate-controlled and non-climate facilities have different load profiles. Contract structure should reflect the actual portfolio mix, not an average.

Where your facility sits

Texas has four investor-owned TDUs plus municipal utilities. Oncor covers North Texas, CenterPoint covers Greater Houston, AEP Texas covers South and West Texas, and TNMP covers non-contiguous zones. Austin Energy and CPS Energy are municipal utilities that do not allow retail choice. See all Texas cities for coverage detail.

Where self storage operators overpay

Letting the contract roll to month-to-month: Holdover rates run well above market.

Treating all facilities the same in a portfolio: Climate-controlled and non-climate facilities have different load profiles, different demand exposures, and different seasonal patterns. A one-size-fits-all contract leaves pricing on the table.

Signing before a climate-controlled expansion: Converting non-climate units or adding a new climate-controlled building materially changes load. A 36-month contract signed before expansion creates a mismatch.

Comparing only cents per kWh: Pass-throughs and bandwidth penalties change the real cost.

Overlooking LED retrofit timing: A planned LED retrofit changes future usage. If retrofit is on the near-term capital plan, model the post-retrofit usage into the contract bandwidth.

Timing the renewal

Start before contract expiry. For a single facility, three to six months of runway is enough. For a portfolio or a large climate-controlled facility, six to nine months is safer.

The single most avoidable mistake is starting in the final 30 days.

How Electric Decisions runs a self storage procurement

Five documented steps. Same process on a single facility, same process on a 50-facility portfolio.

Step 1: Intake: We pull your last 12 months of usage from the TDU through a Letter of Authorization and profile every meter, flagging climate-controlled and non-climate facilities separately.

Step 2: Reference: We benchmark your current all-in cost against the live ERCOT forward curve.

Step 3: Competition: We run an identical-specs RFP against the suppliers who bid your zone or zones competitively.

Step 4: Contract: We red-line the paperwork in plain English. ETF, bandwidth, material change clause, pass-through caps, holdover language.

Step 5: Execution: We manage the switch and watch the market through your term.
