Digital Optimization Platform to Increase Efficiency and Lower Costs for Solar Tower Plants

energyPilotedTRL 7

Imagine a giant mirror array focusing sunlight to heat a tower; if one mirror is slightly off, you lose energy. This project creates a digital 'brain' that constantly checks every mirror and predicts when parts will break. It's like giving a solar plant a high-tech health monitor and a GPS to ensure every ray of sun is used perfectly.

The business problem

What needed solving

CSP tower plants suffer from efficiency losses due to poor heliostat calibration and high costs from reactive maintenance. There is a lack of integrated digital tools to optimize energy dispatch and plant operations.

The solution

What was built

A single integrated platform containing four tools: a heliostat calibration tool, a Digital Twin of the solar field/receiver, an Energy Management System for dispatch, and a predictive O&M tool.

Who can put this to work

Renewable Energy
enterprise
Target: CSP Plant Operator

If you are a plant operator dealing with high operational costs and energy loss — this project developed a single platform integrating four digital tools that optimizes decision-making and increases plant efficiency. It is being validated in 2 commercial tower plants to ensure real-world performance.

Software Development
SME
Target: Industrial Digitalization SME

If you are a software provider dealing with a lack of specialized tools for solar thermal energy — this project developed a Digital Twin and an Energy Management System. This allows you to offer high-value, interoperable digital services to the European CSP sector.

Energy Infrastructure
mid-size
Target: Solar Field Maintenance Firm

If you are a maintenance company dealing with reactive, costly repairs — this project developed a predictive tool for enhanced Operation and Maintenance (O&M). This shifts your business model from fixing broken parts to preventing failures before they happen.

Frequently asked

Quick answers

How much does the software cost or what is the price per plant?

Based on available project data, specific pricing or cost figures for the digital tools are not provided.

Is this technology tested at an industrial scale?

Yes, the tools are being tested in 2 experimental facilities and 2 commercial tower plants, including the Khi Solar One and Cerro Dominador plants.

Who owns the IP and how is licensing handled?

Based on available project data, the specific IP and licensing agreements are not detailed in the project objective.

How long does the validation process take?

The demonstration period for the tools is extended to 1.5 years to capture data across two distinct seasons.

Can these tools be integrated into existing plant software?

Yes, the project focuses on maturing four interoperable tools and integrating them into a single platform for collective data processing.

Consortium

Who built it

The consortium is highly balanced for commercialization, featuring 9 partners across 4 countries. With a 33% industry ratio (3 industrial partners) and 2 SMEs, the project blends academic research (5 research entities) with the practical needs of major energy players like COX and ACCIONA.
