Mesa thermal storage unit at a commercial building
Commercial thermal storage · WNY

Cut your demand charge.

Mesa is a bolt-on thermal storage unit that shaves the peak-demand portion of your electric bill — the hidden charge that runs $8,000–$15,000 a year for a typical Western New York commercial building.

FAIL-SAFE It can't break your building
01 What it is

A heat pump, a storage tank, and a controller — working while your building runs normally.

Mesa charges off-peak when power is cheap, stores the energy as heat or cold, and dispatches it during your peak window so the spike that sets your demand charge never forms. It connects at a single existing interface — air-side or hydronic.

I
Charge
Off-peak, when power is cheapest.
II
Store
As heat or cold, in an insulated tank.
III
Dispatch
During your peak, so the spike never forms.
Scope of work
No HVAC replacement
Your existing equipment stays exactly where it is.
No BAS integration
No controls project, no building-automation work, no IT.
No construction
One mechanical tie-in. Installed in about five days.
02 The daily cycle

Your demand charge is set by one daily peak. Mesa shaves the top off it.

Mesa quietly charges storage while the building is calm, then discharges into your peak — holding your billed demand flat instead of letting it spike. The tall part of the curve simply never reaches the meter.

One mechanical interface. Running the same day. The building never stops.

03 Why it's low-risk

You're buying a product, not a dependency.

I

Fail-safe by design

Mesa never commands your HVAC or touches your setpoints. If it ever faults, your existing system runs exactly as it did before — there is nothing to break that wasn't already there.

II

Behind the meter

Mesa sits on the building side of your meter — no utility permission, no interconnection agreement, no metering changes. The install touches one mechanical interface and is running the same day.

04 The pilot program

A 12- to 18-month pilot, handled end to end by Calor.

Calor provides, installs, and operates one Mesa unit at your facility for the duration of the pilot term. Your obligations end at the energy assessment and site survey — Calor arranges installation and implementation, and the system runs independently with no operational or maintenance burden on your staff.

Summary of key terms
Pilot term 12–18 months from commissioning
Cost to the site None. No charge for the unit, delivery, or installation.
Your obligations Assessment and site survey access, 24/7 unit access for servicing, and monthly utility bills
Siting Outdoor location, approx. 5′W × 8′L × 8′H of clear space
Lead time 12–18 weeks from agreement to delivery
After the term The unit may remain on site, subject to a load-shedding fee. You keep the load-shedding benefit and the monthly reduction in energy costs.
Monthly reporting
Monthly energy analysis statements confirming the unit's functionality, plus quarterly or semiannual reviews of the data and how it's being used to load-shift your building.
Confidentiality
Under the pilot agreement, Calor will not use or distribute un-anonymized building or energy-use data to any outside party, except as agreed for case studies and references under the pilot agreement.
05 How the pilot works

Eight steps from first walkthrough to a running unit — most of them ours.

After the assessment and site survey, no further action is required of you. Calor manufactures, delivers, installs, and operates the unit.

01
Energy assessment
A free, no-obligation visit to your facility. Have twelve months of energy bills on hand and a facilities contact who can walk the building.
02
Site survey
Same visit: we establish where the unit will sit. It installs outdoors and needs roughly 5′W × 8′L × 8′H of clear space.
03
Agreement
If the building qualifies, you execute a Calor Pilot Site Agreement covering timelines, integration, and implementation.
04
Manufacture & calibration
Calor builds and calibrates your unit before delivery — approximately 12–18 weeks.
05
Installation
Calor coordinates the install with a licensed HVAC installer and your facilities manager — about five days on site.
06
Integration & metering
Once integrated and configured, Calor establishes backend connectivity and metering of the unit.
07
Operation
No onsite maintenance from your staff or from Calor. The unit runs independently and is monitored by Calor 24 hours a day.
08
Reporting
Monthly statements arrive from day one, with quarterly or semiannual reviews of the data behind them.

06 Become a pilot site

Be one of Mesa's founding pilot sites.

Calor is enrolling a limited number of Western New York commercial buildings. It starts with a free, no-obligation energy assessment — twelve months of energy bills and a walk of the building. From there, Calor handles everything else.

This page is a summary of the Mesa pilot program provided for discussion purposes and does not constitute a binding agreement or an offer capable of acceptance. The terms of the pilot are governed solely by the executed Calor Pilot Site Agreement. Performance and savings figures are modeled estimates based on a representative building's load profile and tariff; they are not guarantees, and actual results vary. Site-specific figures are provided in the energy assessment.
