A natural gas-fired AE-T100NG MT has been successfully commissioned on a hilltop resort overlooking the world famous Lake Garda in Italy.
The combined heat and power system is feeding the Leafy Resort Wellness Spa in Gargnano (BS), twice voted the best Spa in the world in 2016. The luxury facility was recognized with both a World Spa and Wellness Award 2016 (best SPA destination in the world) and a Connoisseur Circle Hospitality Award 2016 (Best luxury hotel from 1000 prestigious hotels worldwide).
Mr Alcide Leali Jr, Managing Director of the family-owned Resort, told Decentralized Energy: “With the vision to create Places of our Dreams, the vision of Lefay Resorts project is to become the Italian reference brand in the international market of luxury wellness holidays through the creation of a collection of eco-resorts according to the Italian style and living and the new Lefay concept of luxury. Sustainability for us means developing a business model designed to achieve economic and financial results, while fully respecting the environment and promoting the development of local areas and also the professional growth of the company's Staff.”
“Technological plants we use have to comply with the concept of excellence. Indeed just adjacent to the resort is an advanced power plant facility perfectly integrated inside the natural environment of Lefay’s park. It possesses best-in-class systems for simultaneous generation of electrical, heating and cooling energies.”
The trigenerative plant comprises:
· Ansaldo Energia AE-T100 Micro Gas Turbine adding to the existing turbine already in situ. Together these provide an electrical availability of 200 kWe and a thermal availability of more than 300 kWth (in the form of hot water), both cover respective energetic baseloads;
· Part of full hot water flow produced by both turbines is provided to a Li-Br absorption chiller which generates cooling energy in the form of cold water. Absorber-available cooling power reaches 200 kWf and cold water goes to the resort at 5°C and backs at 8°C.
Also included inside this technical area are:
· a biomass boiler (fed by woodchips) and
· a high-efficiency natural gas boiler,
both producing hot water to cover thermal peak demand along colder seasons.
“Ansaldo’s Micro Gas Turbines division manages also an exclusive family of Key-Accounts”, says Riccardo Ori, Sales - Micro Gas Turbines at Ansaldo Energia, “and Lefay Resort is without a doubt part of this exclusive family; it is a strategic client for us and we are really proud to have our AE-T100 up and running in a facility so dedicated to excellence. Lefay Resort chose our technology as our cutting-edge CHP solution runs with minimal emissions levels”.
The solution also caters for the hotel’s specifications with regard to noise pollution by having 73-dBa noise minimizing equipment housed in a small cabinet. The AE-T100 trigeneration system also minimizes emissions to less that the conservative threshold of 15 ppm(v) for both NOx and CO (ISO-Cs).
In fitting with the high standards of the spa, a high-speed gas turbine rotor running at 70.000 rpm, eliminates vibrations from the process of providing power, heat and cooling.
Ori says all of these details permit Lefay Resort to comply with ambitious environmental-care targets. “Indeed their attainments have been documented every year as part of the resort’s Sustainability Report, which is a very important document for all companies these days, but moreover for luxury accommodations where everything must be at the highest levels of quality, power technologies included.”
For many who use such exclusive resorts, sustainability is an important factor, with more and more people preferring an environmentally-friendly relaxing vacation.
Ansaldo has a growing number of customers in the fine real estate sector requesting Italian-made micro gas turbine CHP solutions and is increasingly providing its AE T100 Micro-GT as a solution for such clients. A high thermal/electrical powers ratio and flexibility in water heat range, and the resultant thermal efficiencies are all attractive features for the company’s client base.
