Overview
Ompex AG is a Swiss energy service company headquartered in Zurich, with a second office in St. Gallen. Founded in 2006 and wholly privately owned, it describes itself as the first truly independent energy service provider in the Swiss energy market. Rather than generating or retailing energy itself, Ompex positions itself as a partner to energy utilities and large industrial consumers, supporting them across procurement, marketing and sales in liberalised European energy markets. The company's core services cover consulting, trading and portfolio management, process support, and market access and settlement for electricity, gas, CO2 and guarantees of origin. Ompex states that it holds direct market access in several European countries, including its own balancing groups, and that it is a registered member of international power and gas exchanges and listed as an independent participant in various cross-border auctions. It also develops customised online IT tools for energy projects and offers price analyses and support in building modern energy desks. Ompex presents itself as personal, transparent and independent, available 365 days a year. Its stated strategy rests on open, liberalised energy markets, profitable energy procurement and sustainable, resource-conserving services and products. The company frames its work as an active contribution to the transformation from fossil power generation to renewable energy, helping clients manage short-term fluctuating feed-in from sources such as wind and solar. It reports more than 35 employees and publishes a BESS index (battery energy storage system benchmark) for the Swiss market on its website. As a privately held Swiss company, Ompex is not listed on a stock exchange. Its client base centres on energy supply companies and large industry, and its geographic focus is Switzerland with operational reach into the wider European energy markets through exchange membership and cross-border market access.
History
Ompex AG was founded in 2006 and is headquartered in Zurich, Switzerland, with a further office in St. Gallen. From its inception the company has been wholly privately owned, a status it still reports today, and it has grown to more than 35 employees. Ompex built its business around the liberalisation of European energy markets. Instead of owning generation assets or serving end consumers directly, it developed a service model for energy supply companies and large industrial clients: consulting, trading and portfolio management, process support, and market access and settlement for electricity, gas, CO2 and guarantees of origin. Over time the company established direct market access in several European countries, including its own balancing groups, and became a registered member of international power and gas exchanges as well as an independent participant in various cross-border auctions. In its own account of its mission, Ompex describes itself as the first truly independent energy service provider in the Swiss energy market, a positioning built on acting without conflicts of interest and offering open opinions to clients, authorities and the press. Its strategy has been organised around three pillars: open and liberalised markets, profitable energy procurement, and sustainable, resource-conserving services and products. The company frames its work as supporting the transformation from fossil power generation to renewable energy, helping clients integrate short-term fluctuating feed-in from wind and solar. More recently Ompex has extended its public-facing activities to include market benchmarks, publishing a BESS index (battery energy storage system benchmark) for the Swiss market on its website, alongside its established energy trading and advisory services. The company continues to operate from Zurich and St. Gallen and to serve utilities and large industry across Switzerland and wider European markets.
