ABB successfully launched its online oil reclamation service to tackle the declining condition of transformer oil at Deeside Power Station. The power station had been struggling with rising acidity and corrosive sulfur levels in the transformer oil, resulting in increased usage of passivator chemicals, such as Irgamet 39. | The benefits of this solution were significant. First, it provided a cost-effective alternative to traditional maintenance methods, saving the power station from expensive equipment replacement. Second, the online nature of the service meant that there was no need to shut down operations, ensuring an uninterrupted power supply. Third, the treatment helped preserve the Degree of Polymerization (DP) of the paper insulation inside the transformers, which is crucial for their long-term reliability and performance. Lastly, the approach was environmentally friendly, as it reduced the need to dispose of large volumes of contaminated oil. |

Siemens Energy is tackling the critical shortage of large power transformers (LPTs) in the US by investing USD 150 million to establish its first domestic LPT manufacturing facility in Charlotte, North Carolina. This strategic initiative aims to expand Siemens Energy's presence in the market and enhance refurbishment capabilities to strengthen grid infrastructure. The facility is expected to produce 24 LPTs annually at launch, with plans to increase production to 57 units per year. Additionally, it will refurbish 12 to 24 units each year. Construction of the facility began in 2024, with the first transformers anticipated to be ready by early 2026. This project is expected to create approximately 559 new jobs in logistics, assembly, and mechanical roles. | This investment significantly reduces lead times—currently up to five years—by increasing the domestic supply of critical transformers, which are essential for transmission and distribution networks, renewable energy integration, and power-hungry AI/data center projects. By localizing production and refurbishment, Siemens Energy enhances grid reliability, supports decarbonization goals, and mitigates supply chain risks, leveraging its century-long expertise in transformer technology. |

A power transformer is a vital component in the transmission and distribution of electrical energy, designed to adjust voltage levels between different segments of the power grid. Its core function is to either step up (increase) or step down (decrease) voltage, enabling electricity to be transmitted efficiently over long distances while minimizing energy losses. This capability is essential for linking generation facilities to distribution networks and ensuring a stable and reliable power supply to end users. Structurally, a power transformer consists of a magnetic core—typically made of silicon steel—and insulated copper or aluminum windings. These windings operate on the principle of electromagnetic induction: when alternating current flows through the primary winding, it generates a magnetic field in the core, which then induces a voltage in the secondary winding. The resulting output voltage is determined by the ratio of turns between the primary and secondary coils. For example, if the secondary coil has fewer turns than the primary, the transformer acts as a step-down unit, reducing the voltage for safe and efficient local distribution.
