Repsol's path to sustainable electrification
By replacing a steam turbine with an electric motor, Repsol Olefins has managed to reduce its energy consumption by 25% and its COâ‚‚ emissions as part of its commitment to sustainable electrification.
One goal: reduce COâ‚‚ emissions and increase sustainability
How it all began
With thousands of employees and more than 70 years of experience, the Repsol Industrial Complex in Puertollano generates a wide variety of products in its expansive facilities. Energy efficiency is one of the key issues in day-to-day operations of this complex, which is why the goal was set to reduce COâ‚‚ emissions and produce in a more sustainable way.
The electrification of our compressor at the Puertollano Olefins Unit, replacing the previous steam turbine, is without a doubt an important milestone in this process.

Our technologies have allowed Repsol to achieve its goal
Our SINAMICS PERFECT HARMONY GH180 (now Innomotics Perfect Harmony GH180) medium voltage drive provides the power and performance required in this project: 8.25 Megawatts at 5800 revolutions per minute. To get an idea of the magnitude of this data, this represents the daily consumption equivalent to a town with 3000 residents.
We needed an efficient solution, with a high degree of technology that would ensure a high system availability. After the replacement, our goal was for the gas compressor to operate continuously for at least five years. And Innomotics (former Siemens Large Drives) was able to supply us with this technology.

At the time the pictures were taken, Innomotics was part of Siemens*, which is why Siemens* brands can still be seen in some photos, videos and documents.
A huge technological and logistical challenge
The project has been a huge challenge. First and foremost, the turbine had to be replaced by an electric variable speed drive – representing state-of-the-art technology and innovation. And secondly, the project had to integrate a high-speed motor from the Innomotics (former Siemens Large Drives) factory in Berlin with a frequency converter from the New Kensington plant (United States), highlights Ricardo Andrino, Project Manager Project P-64 at Innomotics (former Siemens Large Drives).
Innomotics' (former Siemens Large Drives) proposal was convincing from the start because it included full testing in the factories, witnessed by customer personnel. And of course, the Innomotics Digital Portfolio has given us the added value that we needed.
The Innomotics (former Siemens Large Drives) drive system is redundantly configured so that there are no unscheduled downtimes. Furthermore, the innovative SIDRIVE IQ (now Inspire IQ) digitization technology allows Repsol to remotely monitor its frequency converter. This digital platform enables real-time access to all the data captured from the frequency converter. This data is continuously evaluated in the cloud and improves decision-making in an IoT ecosystem.
Building an environmentally friendly future
On the road to sustainability
The collaboration between Repsol and Innomotics (former Siemens Large Drives) has meant that Repsol can produce more efficiently, more sustainably and in a more environmentally friendly fashion.
The launch of this ambitious project has opened the doors to a very relevant market thanks to the European Union's sustainability policy. We are very proud to have become a reference partner for Repsol and we hope to be able to win new projects in the near future.
This represents a milestone when it comes to sustainability and environmental protection, which will generate synergies to sustain the future of our country and environment.
