ABB TO MODERNISE AUTOMATION SYSTEMS AT SOLAR POWER PLANTS

diagnostics without attending site. This has reduced routine field visits, improved response times and supported safer working practices.
BUILT FOR RESILIENCE AND COMPLIANCE
Kingfisher’s architecture also supports compliance and auditability – a critical advantage for utilities navigating workforce shortages and an increasingly complex regulatory landscape. With built-in data logging, secure remote access and standardised templates, smaller or less specialised teams can streamline commissioning, monitor performance and demonstrate regulatory alignment with confidence. Telemetry is no longer just about hardware performance. It’s about empowering organisations to operate safely and effectively despite a shrinking talent pool. Ultimately, addressing the workforce pressures highlighted in the Water Industry Labour Report will require more than recruitment alone. It demands tools that allow utilities to do more with fewer people while protecting institutional knowledge. By transforming remote telemetry systems like the Kingfisher into a strategic platform for remote control, diagnostics and compliance, utilities can meet today’s workforce challenges head-on – and build a more sustainable operational model for the future.

BB has been selected by independent power producer ContourGlobal to replace the solar field control system at four Concentrated Solar Power (CSP) facilities in southwest Spain, enabling the secure and efficient integration of renewable power into national electricity grids to support European energy transition efforts.
The existing systems, which have been in operation for more than 10 years, will be migrated to ABB Ability Symphony Plus SCADA, based on ABB’s AC500 and AC 800M platforms. These will provide each CSP plant with a scalable, high-performance control solution that ensures long-term system availability and enhanced cyber security. Solar tracking algorithms within ABB’s system calculate the sun’s position every 480 milliseconds with an accuracy of 0.0001 degrees. This enables the continuous positioning of 7,400 mirrors at the facilities to maximise efficiency, while correcting for drift, terrain tilt and variable weather conditions. ABB’s solution offers a robust and flexible approach to modernising ContourGlobal‘s CSP assets. The ability to integrate seamlessly with existing third-party controls and allow phased replacement minimises disruption and ensures continued operational efficiency and reliability. CSP has been identified as a significant contributor to the transformation of the European energy system by providing dispatchable electricity, which can complement the integration of variable output renewables into the grid. The EU funds CSP research projects to identify more efficient cycles and components, as well as contributing to financing first-of-a-kind plants.
While photovoltaic solar panels generate electricity directly, CSP plants use fields of mirrors to concentrate sunlight onto a receiver point. The concentrated heat warms a fluid, which is then used to produce steam and drive a turbine. This process can allow CSP plants to store energy and generate electricity when the sun is not shining.
“Modernising automation assets is just as important as installing new ones if we are to achieve a secure and sustainable energy system to meet growing demand,” says Per Erik Holsten, president of ABB’s Energy Industries division. “By applying our expertise in automation, electrification and digitalisation, we are enabling operators like ContourGlobal extend the life and efficiency of their facilities and deliver reliable renewable power to the grid.”
ABB’s scope at each of the four CSP plants includes a fully integrated control and data management architecture, incorporating Symphony Plus SCADA, S+ Historian functionality, AC 800M control cabinets and AC500 local solar field controllers. Advanced cyber security measures, such as automated backups, certified patching and antivirus management, will reinforce system integrity and compliance.
The ContourGlobal facilities are located in Majadas, approximately 210 km from Madrid; in Orellana, approximately 300 km from Madrid; and in Palma del Río, around 90 km from Seville, where both Solar Fields 1 and 2 will be upgraded. The migration is scheduled for completion by February 2027.
