Hammond Power Solutions is a leading North American manufacturer of dry-type transformers and power quality products. These are crucial for electrical power distribution and control in various sectors. The company was recognized as the top-performing company in the 2024 TSX30 ranking.

Founded in 1917 in Guelph, Ontario, as O.S. Hammond and Son by Oliver Hammond, the company initially focused on tools for the foundry industry. It soon expanded to produce tube radio sets and battery chargers, adhering to a philosophy of building products as if for personal use.

Hammond Power Solutions is now North America's largest dry-type transformer manufacturer, with facilities in Canada, the US, Mexico, and India. As of August 2025, its market capitalization reached $1.00 billion USD. This growth reflects a century of strategic development and market leadership, building upon its foundational principles. The company's product range includes essential components for electrical systems, such as those analyzed in a Hammond Power Solutions Porter's Five Forces Analysis.

The Hammond Power Solutions history begins in 1917 when Oliver Hammond established O.S. Hammond and Son in Guelph, Ontario. Initially focused on providing tools for the foundry industry, the company soon pivoted to manufacturing tube radio sets and battery chargers, driven by the burgeoning radio market.

The Founding of Hammond Power Solutions

Oliver Hammond founded O.S. Hammond and Son in 1917, laying the groundwork for what would become a significant player in the electrical manufacturing sector. The company's early philosophy was simple: ‘Build the product like you were going to use it yourself’.

• Founded in 1917 by Oliver Hammond in Guelph, Ontario.
• Initial focus on foundry tools.
• Pivoted to tube radio sets and battery chargers between 1919 and 1927.
• Adoption of the guiding principle: ‘Build the product like you were going to use it yourself’.

Following Oliver Hammond's passing in 1925, his four eldest sons took the helm. A significant shift occurred in 1927 when the company was officially renamed Hammond Manufacturing. This marked a strategic move away from radio production and towards the manufacturing of transformers and filter chokes, essential components for broadcast transmitters and AC radio sets. This early adaptation to technological advancements was a key factor in the company's sustained growth and success, demonstrating an early understanding of market needs and the importance of a robust Growth Strategy of Hammond Power Solutions.
