Nobian and PZEM sign a power purchase agreement (PPA) for the purchase of electricity from the Dutch offshore wind park Gemini. Nobian will purchase 300 GWh of renewable energy in 2024, increasing to 500 GWh in 2025. The power purchase agreement covers an equivalent of 10-15% of Nobian’s annual electricity consumption and comparable to consumption 90,000 – 150,000 households. A total saving of more than 500,000 tonnes of CO₂ emissions. The agreement is an important next step in achieving Nobian’s goal of 100% renewable energy and carbon neutrality by 2040 and enables PZEM to realise its ambitions as a reliable player actively contributing to shaping the future of the energy sector.

Gemini Wind Park

The Gemini Wind Park, located in the Dutch North Sea 85 kilometres off the Groningen coastline, is one of the Netherlands’ largest wind farms and is a crucial building block in the renewable energy infrastructure. The capacity of the total wind farm is 600 MW (150 wind turbines with a capacity of 4 MW each), good for an annual electricity production of about 2.5 TWh, equitvalent to the consumption of about 750,000 households. This is a saving of 1.5 mln tonnes of CO₂ emissions.

Balancing supply and demand

Operator PZEM, the buyer and programme responsible party of the power generated by Gemini, is responsible for balancing the production of the wind farm. PZEM acts as the crucial link between the supply and demand of renewable energy.
This means they constantly monitor the balance between the amount of energy generated and market demand. PZEM’s ambition is to seamlessly match production and consumption of energy at the hourly level.

"We are very pleased with the confidence Nobian is placing in PZEM. Electricity production from renewable energy sources is increasing rapidly. We aim for a balanced mix of different energy sources and are committed to continuous and sustainable growth in our production, supply and trading activities. We achieve this partly through long-term purchase contracts, such as the contract with Nobian"

About Nobian   

Nobian is a European market leader in the production of salt, essential chemicals and energy for industries ranging from construction and cleaning to pharmaceuticals and water treatment. We excel in the safe and reliable supply of high-purity salt, chlor-alkali, chloromethane and hydrogen, thanks to our integrated value chain with modern production sites in the Netherlands, Germany and Denmark. We have a strong history of salt production dating back more than 100 years to 1918, and we have extensive experience in underground energy storage. Our 1,600 employees are committed to becoming safer, more efficient and more sustainable. This is how we ensure that today’s essential products continue to improve our lives tomorrow through chemistry you can count on. Nobian is wholly owned by Carlyle Group and GIC.


Indispensable raw material  
Salt, present and extractable in the Netherlands, is an indispensable raw material for much of the Dutch chemical industry. About 40% of organic chemistry depends on salt. Salt chemistry provides essential building blocks for many everyday products such as building materials, pharmaceuticals, contact lenses and (sun)glasses, cleaning and cleansing agents, flooring, PVC, paper and aluminium production, concrete substitutes and water purification. It also forms the basis for important components of the ‘new economy’ such as insulation materials, LED lamps, wind turbine blades and lithium batteries.

Grow Greener Together  
Last year, for the second year in a row, Nobian received an Ecovadis platinum rating for the objectives from its “Grow Greener Together” sustainability programme. EcoVadis is the world’s most trusted provider of business sustainability ratings. This maintains Nobian’s position in the top 1% of more than 90,000 companies rated by EcoVadis worldwide.

"This agreement with PZEM is an important next step on our road to carbon neutrality with 100% renewable energy by 2040. We are committed to buying electricity where we operate. This renewable electricity from the Gemini Wind Park will be used in our salt production and electrolysis. This makes an important contribution to making our products and energy use more sustainable, as part of our 'Grow Greener Together' strategy."
