How our service works

A continuous cycle of energy management.

Our service is not a project with a completion date. We audit how your facility uses energy, propose an integrated solution, engineer and construct it, then operate and maintain what we built. What we learn running the plant informs the next audit, so efficiency keeps improving and lifecycle cost keeps falling long after commissioning. We are users before we are engineers. Decades spent operating our own plants taught us what performs in the field and what does not, and that is the know-how we bring to your site. One organization is accountable at every stage, so nothing is lost in a handoff between vendors.

ONE PARTNER, SIX JOBS

Responsibilities we take on, and stay accountable for.

Your team stays focused on production. We assume the energy system, including the capital behind it.

Design & construction

Engineered, procured, and built in house.

Funding & investment

Our capital, off your balance sheet.

Operations & maintenance

Planned and corrective work, performed by our own crews.

Remote monitoring

Continuous oversight, with faults caught early.

Energy-saving solutions

Tuning that keeps efficiency improving year over year.

Fuel & power procurement

Gas and electricity sourced on your behalf.

Greenhouse Gas Reduction

The right combination for your facility.

No two facilities decarbonize the same way. We assess what your site can actually support, combine these measures into one solution, and hold it against your reduction goal. Efficiency comes first because it costs the least. Certificates come last, to close what remains.

Energy efficiency

The lowest cost carbon reduction available at any site.

Optimal operation control

Remote tuning that holds the plant at its best operating point.

Solar

On-site PV where roof and land allow.

Renewable natural gas

Pipeline-quality low-carbon gas. Runs in your existing equipment, no retrofit.

Renewable energy certificates

Certified renewable power, closing the gap the other measures cannot.

Target

2050

Reduction goal, with documentation your board can report on.
