Maria Luz Cruz Aparicio – IBERDROLA

For some decades now, digitalisation has been an essential part of Iberdrola’s business and the use of information technologies has become a fundamental asset for the company. Currently, Iberdrola digitally manages its electricity generation assets and has transformed its networks into intelligent ones with digital tools and Artificial Intelligence. Regarding Renewables, Iberdrola has been digitalizing the operations of its solar, wind and hydro assets for over a decade. Iberdrola has developed its own technologies that predict renewable power generation, optimize performance and manage operations, using digital technologies. Below you can find some examples:

METEOFLOW- Machine learning & Big Data

Its first digital tool for renewable generation is METEOFLOW. Built in 2004, it predicts wind power output. The model has developed over time to incorporate two terabytes of meteorological information and windfarm data per day, using machine learning and big data techniques. The algorithm runs through 10,000 sets of meteorological data for each turbine and time period, predicting power output.

ASPA- Digital Twins

In 2017, Iberdrola launched a software ‘advanced system of predictive analysis’ (ASPA) on its onshore wind fleet. By comparing real-time data to the digital twin of each turbine, ASPA identifies future turbine failures, reducing time and cost. Additional asset lifecycle management software tools contribute to maximizing revenue.

The Wikinger offshore wind farm is one of the facilities selected for implementing the Romeo project.

ROMEO Project (Internet of Things)

The Romeo Project (Reliable OM decision tools and strategies for high LCoE reduction on offshore wind) aims to develop advanced technological solutions that enable the operation and maintenance costs (O&M) of offshore wind power facilities to be reduced. A flexible and interoperable Cloud and Internet of Things (IoT) platform will provide an advanced analytics ecosystem for failure diagnosis and prognosis models to better understand the real time behaviour of the main components of WTGs under operational conditions.

SEDAR project (High-Resolution Wind Power Simulation)

Iberdrola is working with the Barcelona Supercomputing Centre (BSC) in the SEDAR PROJECT to develop a simulation software to estimate the production capacity of an offshore or onshore wind farm throughout its useful life before it is built. The system calculates the perfect locations for the installation of wind turbines, optimising the design of the wind farm to maximise the production of energy. Currently, Iberdrola is using this software to design 15 onshore wind farms in Brazil, Mexico and the US.

Renewable Energy Operating Centre (CORE)- Internet of Things

Thanks to the technology Internet of Things (IoT), Iberdrola has deployed a technology to monitor and operate renewable generation facilities from a single dispatch center called CORE. Currently, Iberdrola has four Centers, in Toledo (Spain), Portland (USA), Glasgow (UK) and Río de Janeiro (Brazil). +5 million signals from 11k wind turbines.

  • The Toledo Renewable Energy Operations Centre, a pioneer in the sector, provides service to 230 wind farms and 70 mini-hydro power stations, with an installed capacity of 8,200MW, 24 hours a day, 365 days a year. It handles around 800,000 signals from 6,208 wind turbines in eight countries.
  • In Portland, the centre has become the most advanced renewable energy facility in the US, handling around 2,000,000 signals from some 3,526 of the company’s wind turbines in that country, with an installed capacity of 6.730MW.
  • In Glasgow, Iberdrola monitors and control more than 1,300 wind turbines (on-shore and off-shore), a total of 2.660 MW installed power from 36 wind farms located in UK and Germany. In total more than 500,000 online variables.
  • The CORE in Río de Janeiro (Brazil) was opened in 2019 and operates 516 MW of wind energy distributed across 14 wind farms.

Additionally, a fifth CORE will open in 2020 to manage the group’s hydraulic plants — a task currently shared by four centres — paving the way for large hydro in the CORE platform
