About ESCO VOLTAJ
An energy service company from Chișinău. Since 2007 we have been designing, financing and delivering energy-efficiency, renewable-energy and power-network solutions in the Republic of Moldova.
Who we are
Engineers who answer for the result.
ESCO-VOLTAJ S.R.L. was registered on 11 December 2007. Since then the team has delivered more than 200 wind, solar, energy-efficiency and power-network projects.
Improving the quality of life is the main goal we want to achieve. We are driven by the desire to bring energy-efficiency solutions to the society we live in.
We are open to the needs of every consumer: we analyse and identify feasible solutions that precisely match the client's requirements — from an installation in an industrial hall to a solar park connected to the grid.
“Your satisfaction is our business card.”
The ESCO model
The investment pays for itself from the savings.
An ESCO (Energy Service Company) designs, finances and delivers energy-efficiency solutions, and the investment is repaid from the savings achieved.
The cycle has five steps — energy audit, design, financing, construction and measured savings — and then repeats: the savings fund the next measures.
- Energy audit
- Design
- Financing
- Construction
- Measured savings
