The energy industry is faced with systemic challenges that can only be solved by optimising the whole system from power plant and energy storage to grid – and increasing and optimising the use of renewables. This is a complex task that requires a holistic approach, but it delivers multiple benefits.
Let Decarbonisation Services help you achieve your goals by finding the optimal balance between commercial, operational and ESG (Environmental, Social and Governance) factors. With outcome-based agreements, you can be certain that we will only recommend what you really need – and go the extra mile as our fee is linked to your success.
Let us diagnose your unique challenge, model the optimal yet feasible solution, and implement it with our GEMS Digital Energy Platform.
Our holistic approach offers you all the services, equipment, software and support you need every step of the way over the whole lifecycle.
Helping you supply affordable energy while meeting your commercial, operational and ESG targets.
We use our industry understanding and power system modelling tools and capabilities to identify your challenges whether current operational or future ones brought on by renewable integration.
We model both the optimal solution to meet your needs and its feasibility using techno-economic analysis (cost optimisation / minimisation) and dynamic simulations (frequency and voltage stay within limitations). We strive for as accurate real-world conditions as possible.
The solution and support will be implemented with GEMS, our Digital Energy Platform, and a lifecycle agreement.
Our performance in achieving your targets is tracked, and our fee is linked to your targets as defined in the outcome-based service agreement.
Aqualectra and Wärtsilä: A Partnership Driving Decarbonisation
Curaçao is on an ambitious journey to transform its energy landscape—moving from 30% renewable capacity to 70% by 2027. At the heart of this transition is Aqualectra, the island’s trusted energy utility, and Wärtsilä, a global leader in flexible power solutions. Together, they’re shaping a cleaner, more resilient future for over 80,000 households and businesses.
For over 30 years, Wärtsilä has worked hand-in-hand with Aqualectra, evolving from power generation to a pioneering Decarbonisation Services agreement. Today, this collaboration includes advanced grid balancing engines, energy storage systems, and Wärtsilä’s GEMS Digital Energy Platform—optimising energy use across the island. The result? Affordable, reliable, and sustainable electricity for Curaçao’s residents.
Together, we are building a blueprint for resilient and sustainable island energy systems worldwide.

Technology group Wärtsilä’s renewal of its existing Operations and Maintenance (O&M) agreement with QIT Madagascar Minerals S.A (QMM), part of the Rio Tinto group, has been expanded to include a Decarbonisation Agreement. The Agreement is a groundbreaking offering in the energy sector, and allows for optimising all of the assets in the microgrid, including renewable energy usage, thereby not only reducing emissions but also producing notable cost savings. The continued O&M agreement covers QMM’s 24 MW engine power plant located at the company’s ilmenite mineral sands mine at Fort Dauphin in south-eastern Madagascar. The order was booked by Wärtsilä in June 2024.
The key elements of the agreement include optimised dispatch of the plant’s six Wärtsilä 32 engines and QMM’s battery energy storage and renewable assets with Wärtsilä’s GEMS Digital Energy Platform. The GEMS software uses machine learning technology to optimise multiple energy generation assets and ensure maximum utilisation of renewable energy.
“The O&M Agreement with Wärtsilä has been in place since 2008 and we have been pleased with Wärtsilä’s performance. The reliability and efficiency of the power plant are critical to our operations, and we are therefore excited to extend this agreement. The renewed agreement allows us take advantage of Wärtsilä’s competence in power system optimisation and use renewables in the most efficient way, supporting Rio Tinto’s decarbonisation objectives and sustainable mining vision,” says Jean-Francois Richer, Director Integrated Operational Services at QMM.
The hybrid power plant supplies the electricity required to operate the mine and also to the nearby town of Fort Dauphin.
“Our Decarbonisation Agreement is taking energy optimisation to a new level by enabling cost savings, a reduced environmental footprint, and higher efficiency. What is more, the partnership is outcome-based with mutual incentives. This is the way forward in making decarbonised operations a viable reality,” says Christoffer Ek, Director of Decarbonisation Services at Wärtsilä Energy.
“This agreement strengthens our long-lasting partnership with QMM. We are delighted to continue to support their operations, both with our technology and our regional service network. By working in close cooperation with the customer, we are able to ensure a reliable and sustainable power supply to the mine,” adds Kenneth Engblom, Vice President, Africa & Europe at Wärtsilä Energy.
