Energy
Through Altenia, we provide comprehensive support for development, construction, revamping, and maintenance of photovoltaic plants, high-voltage substations and storage systems.
We are the trusted partner for companies and operators investing in the energy sector.
Leveraging the expertise of Altenia’s subsidiaries – Half Bridge Automation and STE Energy – and an integrated approach, we support our clients across four strategic areas:
High voltage
Safe and sustainable turnkey high voltage plants. Advanced maintenance activities to maximize performance and productivity.
We provide our clients with our expertise and know‑how to manage the entire lifecycle of high‑voltage connections – from design and construction to commissioning, through to the revamping of electrical infrastructure such as substations, overhead lines, and underground connections.
Our main services:
- Engineering, Procurement, Construction (EPC)
We design and realize full turnkey electrical infrastructure for industrial clients, data centers, utilities, and energy producers (including substations, overhead lines, and underground connections), ensuring reliable execution timelines and strict regulatory compliance. - Revamping
We offer advanced solutions for the modernization of high‑voltage systems. Through an in‑depth assessment of infrastructure conditions, we support companies in identifying the most strategic interventions to restore performance and integrate innovative technologies. We enhance efficiency, reliability, and operational continuity, while reducing costs and maximizing the value of electrical assets. - Operation & Maintenance (O&M)
We provide comprehensive services for maintenance and monitoring of high‑voltage electrical assets, with the goal of improving performance and reliability. Through preventive and predictive maintenance programs, quick intervention time, and advanced remote‑monitoring systems, we minimize the risk of downtime and maximize operational availability.
Photovoltaics
Complete photovoltaic solutions. Excellence in revamping, repowering, and inverter refurbishment.
We implement end-to-end photovoltaic plants in Engineering, Procurement & Construction (EPC) mode, also providing Operation & Maintenance (O&M) services to maximize plant availability and performance. We specialize in PV revamping, repowering and, through our subsidiary Half Bridge Automation (HBA), in the repair and refurbishment of photovoltaic inverters. We ensure optimal plant performance and the highest possible yield for our customers.
Our main services:
- Engineering, Procurement, Construction (EPC)
With over 1 GWp of PV plants delivered in EPC and revamping mode, we are the ideal partner to support customers through every phase of project development—from permitting and engineering to construction—delivering certified components and high quality standards. - Operation & Maintenance (O&M)
Through tailored maintenance plans carried out on a total capacity of approximately 2 GWp, we are able to optimize the efficiency of photovoltaic plants of various types. Additionally, we own a proprietary platform for real-time ticketing management to maximise plants availability. - Revamping and Repowering
We identify the most appropriate solution to recover the highest levels of performance of the plants and also to repower them – according to customers’ needs – embracing technological progress using the best components in the market and offering a unique in-house service for equipment regeneration. - Photovoltaic Inverter Refurbishment and Repair
We refurbish, repair and rent photovoltaic inverters, carry out solar tracker retrofitting, and develop automation solutions applied to renewable energy generation.
Storage systems
Engineering, construction and logistics for large‑scale plants that ensure grid stability and efficiency.
We provide specialized expertise in the development of energy storage plants.
We support clients with Engineering, Procurement & Construction (EPC) services for utility‑scale storage systems, including design of technical drawings, procurement and logistics management, on‑site construction activities, and comprehensive testing and commissioning to ensure full system reliability.
Our storage solutions maximize the operational efficiency of energy assets: they store excess energy and release it to the grid at the most advantageous times, enabling smart and cost‑effective energy management.
Our key services include:
- Design of technical drawing
We prepare all technical documentation required for the construction of the storage system, from preliminary drawings to as‑built deliverables. - Procurement and logistics
We manage all the aspects related to the procurement of materials needed for the construction of the plant and the logistics of the activities. - Site Management
We take care of all the phases of on‑site activities, supported by dedicated project managers. - Testing & Commissioning
We carry out all the necessary verifications and functional tests to ensure the proper functioning of the plant.
Energy advisory services
Advanced energy diagnostics and customized interventions. Smart monitoring and Energy Performance Contracts for efficiency, cost reduction, and environmental impact mitigation.
We perform energy audits, identify specific areas for improvement, design and deliver tailored solutions to increase efficiency, optimising production processes and minimising environmental impacts.
Our solutions:
- Energy audits
We perform detailed energy audits using energy simulation models to optimise production and management processes for individual departments or entire companies. - Monitoring plans and diagnostics software
We process energy data in real time and provide predictive action plans through complex mathematical and statistical algorithms. - Energy Performance Contracts (EnPC)
We guide our customers in identifying options to improve the energy efficiency of their assets, accompanying them in the implementation of the engineered solutions with an end-to-end approach, from design to the full realization of the works.
