Energy Services
High voltage, photovoltaic, storage solutions and energy advisory services.
Through Altenia, we offer energy solutions: we support our clients in the construction, operation, revamping, and maintenance of photovoltaic systems, high-voltage substations, and energy storage systems.
Terna Energy Solutions is the go-to partner for companies and operators investing in the energy sector. Thanks to the combined expertise of Altenia and Half Bridge Automation and to our multidisciplinary approach, we support our clients across four strategic areas, offering innovative and reliable solutions throughout the entire lifecycle of their facilities.
Safe and sustainable turnkey high voltage plants. Advanced maintenance activities to maximise performance and productivity.
High voltage: EPC, Revamping and O&M service
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 electrical substations, overhead lines, and underground connections.
Engineering, Procurement, Construction (EPC)
Through our EPC service for high-voltage electrical systems, we design and build turnkey electrical infrastructure for industrial customers, data centers, utilities, and energy producers (including electrical substations, overhead lines, and underground cables), ensuring on-time completion and compliance with regulations.
Revamping
We offer advanced solutions for the modernization of high-voltage systems: through a detailed analysis of the condition of the infrastructure, we help companies identify the most strategic interventions to restore performance and integrate innovative technologies. We improve efficiency, reliability, and operational continuity, reducing costs and optimizing the value of electrical assets.
Operation & Maintenance (O&M)
We offer comprehensive Operation & Maintenance services for the maintenance and monitoring of high-voltage electrical assets, with the goal of improving their performance and reliability.
Through preventive and predictive maintenance programs, timely interventions, and advanced remote monitoring systems, we minimize the risk of plant downtime and maximize operational availability.
Comprehensive photovoltaic solutions for utility-scale systems. Excellence in revamping, repowering, and inverter refurbishment.
Photovoltaic plant: EPC, O&M and Revamping solutions
We deliver end-to-end photovoltaic plants under an Engineering, Procurement & Construction (EPC) model, also providing Operation & Maintenance (O&M) services to maximise plant availability and performance. We specialise 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.
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 1.5 GWp, we are able to optimise the efficiency of photovoltaic plants of various types. Additionally, we own a proprietary platform for real-time ticketing management to maximise plant 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, embracing technological progress using the best components in the market and offering a unique in-house service for equipment regeneration.
Refurbishment and repair of photovoltaic inverters
We refurbish, repair and rent photovoltaic inverters, carry out solar tracker retrofitting, and develop automation solutions applied to renewable energy generation.
Engineering, construction and logistics for large-scale plants that ensure grid stability and efficiency.
Utility-scale storage facilities
We offer specialised expertise in the development of energy storage plants. We support clients with Engineering, Procurement & Construction (EPC) services for the implementation of the utility-scale storage systems, including the preparation of technical documents, procurement management and logistics, on-site construction activities, as well as 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.
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 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 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 operation of the plant.
Advanced energy diagnostics and customised interventions. Smart monitoring and Energy Performance Contracts for efficiency, cost reduction, and environmental impact mitigation.
Diagnosis and Energy Efficiency
We perform energy audits, identify specific areas for improvement, design and deliver tailored solutions to increase efficiency, optimising production processes and minimising environmental impacts.
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 proposed solutions with an end-to-end approach, from design to the completion of the works.
