Needs
Martinique Aimé Césaire International Airport wanted to conduct their own energy accounting to optimize their:
Global energy expenses
1 120 758 €/year
(or 9 644 377 kWh/year)
Vehicle
fleet’s gas consumption
27 569 €/year (or 19 527 L/year).
Solutions
Energaya studied the possibility to build and use photovoltaics as a private energy source, through a feasibility study, an improvement program, and an economic report
Step 1: Feasibility study
Energaya analyzed the company’s avenues to build and exploit a photovoltaics power station on the airport site.
Step 2: Improvement program and economic report
Build a photovoltaic power station
To reduce the airport’s energy spendings.
Cost: 6 140 348 €
Savings: 50 % of the current energy spendings
Emissions avoided : 1 970 tons/year of CO2 (-36.29 %)
Sell the extra energy produced
To increase profits by selling extra energy to the French electric utility company
Cost: 3 407 073 €
Profit: 333 508 €/year
Launch an EV fleet and charging stations
For the airport and their staff, to reduce gas costs by using self-produced photovoltaics energy.
Cost: 224 183 €
Savings: 6 889 €/year (i.e., 25% of fuel consumption)
CO2 emissions avoided: 16% of CO2 , 16% of PM10 , 20% of PM2.5 , 30% of NOx.
Create charging stations for external EV users
To encourage green mobility and make profit from self-produced photovoltaics energy.
Results
With an initial investment at 22,950 €, our mission enabled the airport to save 6000 € a year. As a first step, we analyzed their electricity consumption and adjusted their utility contract accordingly. Our suggestions allowed them to recuperate the cost of the entire study in less than 4 years.
