|72||Switzerland's largest alpine solar plant produces electricity|
The Swiss Energy Strategy 2050 focuses on renewable energy. For this energy transition, more electricity must also be produced in winter to close the so-called winter electricity gap. This is precisely where the pioneering project in the Alps comes in.
Switzerland's largest alpine solar plant at 2500 metres above sea level was partially commissioned at the end of 2021. The pioneering AlpinSolar project is expected to produce 3.3 million kilowatt hours of electricity per year from August 2022 - half of it in winter. In this way, solar energy is used at any time of the year and despite the “sea of fog”.
Lombardi is proud to have been entrusted by AlpinSolar Ltd. with the design services for the technical centre of the photovoltaic system for this pioneering project. The services included the SIA phases 32, 41 and 51 to 53 for construction works and heating, ventilation, air conditioning equipments.
|71||New Ritom pumped storage hydropower plant - Last breakthrough|
On February 23, 2022, after almost 12 months of work, the Tunnel Boring Machine completed the excavation of the inclined shaft, connecting the area where the Lake Ritom is located and the donwstream area where the powerhouse of the new Ritom hydroelecrtric power plant has been almost completed.
The new adduction system, completely underground, was excavated starting in 2019 from the bottom of the valley with drill&blast for the first 770 metres. Then, in March 2021, a 3,2 m diameter Tunnel Boring Machine was lanced to excavate the 1,4 km long inclined shaft, overcoming a difference in height of almost 800 metres and raising up to a maximum gradient of 90%.
The next works include the installation and subsequent grouting of a steel lining within the new underground supply system, through which the water from the Lake Ritom, with a hydraulic head of 840 metres, will finally reach two 60 MW Pelton turbines that will be installed in the new Ritom SA powerhouse. In addition, thanks to the installation of a 60 MW pump, there will be the possibility in the future of pumping water up into the Lake Ritom.
The completion of the Project and commissioning of the pumped storage hydropower plant is planned for 2025.

|60||The largest hydroshield TBM in India has been activated|
January 2021: The Municipal Corporation of Greater Mumbai (MCGM) extended the road network of the city with a belt road seaside, already partly realized with the Bandra-Worli Sea-Link bridge, crossing the Mahim bay. This new route, the Mumbai Coastal Road, is 30 km long and mostly on bridges and is closed at its south end by an approx. 4 km long tunnel. This links the Worli interchange to the Marine Drive, also known for its arched shape called the Princess Necklace, towards Nariman Point near the renowned monument of the Gateway of India.
The design of the tunnel was awarded to Lombardi Group by Larsen & Toubro, the company selected for its realization and the largest contractor in India.
After 1 year of design and the completion of the preliminary works, the largest hydroshield TBM in India was lowered in the launching shaft (becoming part of the future ramp to the surface portion of the project) last December. The TBM "Mavala" was activated this January 2021, the 11th day, under the auspices and presence of the state Head Minister of Maharashtra, whose capital city is Mumbai. The TBM is manufactured by China Railway Construction Heavy Industry Co. Ltd. (CRCHI) according to the design specification Lombardi defined and calibrated in cooperation with the contractor and the manufacturer.
The TBM has the largest diameter today in India (12.19 m), allows the installation of precast segments of 35 cm thickness according to the named "universal geometry". On its invert, a precast utility box harbours all canals, technical ducts and the cabling for the ventilation, the lighting, the detection and the tunnel management.
Lombardi Group presence in the project is assured by its Indian branch, the headquarters in Switzerland and the contribution of its Italian branch. It developed the civil work design of the tunnel and the related works (the cross passages and the technical buildings) and the design of the ventilation system, the safety equipment and the electromechanical equipment, as well as the complete SCADA system (Supervisory Control And Data Acquisition) for the operation management and control as well as in case of accident or of maintenance. Fire accidents with 100 MW fire power (heavy truck with high fire potential, according to the Rijkswaterstaat curve) have been simulated by 3D CFD (Computational Fluid Dynamics) analyses in order to define the efficiency and the characteristics of the ventilation system (Saccardo system).
