A key component in the 1920MW HVDC link from Cahora Bassa hydropower plant in Mozambique to South Africa has been successfully refurbished by ABB. At the Songo High Voltage Direct Current (HVDC) converter station, ABB replaced the existing equipment with new DC converter transformers, smoothing reactors, arresters and measuring equipment.
ABB has successfully commissioned the refurbished Songo High Voltage Direct Current (HVDC) converter station in Mozambique, Africa. The station is a key component in the 1920 MW HVDC link transmitting electricity from the Cahora Bassa hydropower plant in Mozambique across a distance of 1,417 kilometers to the South African grid.
The system links Mozambique’s Songo converter station to the Apollo inverter station near Johannesburg, South Africa, by a 1414-km (879-mile), 530-kV HVDC overhead transmission line. This system experienced a long-term service interruption from 1985 to 1997 because of the Mozambican Civil War.
At the Songo High Voltage Direct Current (HVDC) converter station, ABB replaced the existing equipment with new DC converter transformers, smoothing reactors, arresters and measuring equipment. The installation houses the first re-connectable converter transformers to go into operation worldwide.
Although it survived the Mozambican Civil War, the Cahora Bassa dam and hydroelectric power plant requires major refurbishment. The Cahora Bassa dam and hydroelectric power plant located on the Zambezi River in northern Mozambique was the last major construction project in Africa during the era of decolonization from Portugal.
The Songo converter station project is an ideal case study for the refurbishment of existing HVDC systems to enable the transmission of renewable energy resources. One of the largest issues with accessing renewable energy is the transmission system and distribution network upgrades required. Aerial view of the dam's associated switchyard equipment.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
