At the close-out meeting of the NEOSUB project, held on 25 March last, the Basque Energy Cluster met with the project Advisory Committee to present the final project results. The NEOSUB project, centring on the design and development of electricity substations based on eco-design criteria, was coordinated by the Basque Energy Cluster (ACE), and brought together leading sector operators: Red Eléctrica de España, i-DE, Viesgo Distribución and E-REDES. The Advisory Committee rated the findings of the project very highly, urging the group to continue to work on the concepts and delve into the results. Several members of the Advisory Committee expressed an interest in following up on future developments and exploring their potential in greater detail along with the operators.
The NEOSUB project thus comes to an end, having satisfactorily met many of its initial aims. Funded by the Basque Government Hazitek programme, NEOSUB brought together some of the leading manufacturers of electrical equipment in the Basque Country interested in improving the environmental quality of their products.
Led by BOSLAN, the engineering firm which designs electricity substations for major power operators and distributors worldwide, ORMAZABAL, ARTECHE, GE, INGETEAM and ZIV considerably enhanced design and economic and environmental aspects of their products using innovative eco-design and circular economy criteria. ORMAZABAL has conducted in-depth research on a new type of SF6 primary distribution switchgear, which has reduced environmental impact, and the design of new power transformers using a biodegradable dielectric liquid based on plant esters. ARTECHE has designed a new block of secondary terminals for high voltage metering transformers, replacing the former resin-based ones with new aluminium ones. Likewise, GE, INGETEAM and ZIV have reduced consumption and improved the design of their protective and control equipment for substations.
BOSLAN has designed an innovative tool for eco-design of substations, leveraging improvements in equipment and analysing cost and environmental impact throughout all stages of substation lifespan. The tool has been designed using a global approach and validated with the equipment of the manufacturers involved in the project, and also designed to be extended to all types of equipment used in electrical substations. It can also be customised and adapted to other platforms so that it can be used by other operators.
Another company taking part in the project was IK INGENIERIA, which has developed a methodological basis for economic and environmental testing and a tool for analysing environmental and economic cycles to validate substation equipment. Likewise, project technical coordinator TECNALIA provided technological support to equipment manufacturers for the economic and environmental assessment of their products and supported BOSLAN in developing the eco-design tool.
The Basque Energy Cluster, the final member of the consortium, has coordinated communication and dissemination activities as well as setting up and liaising with the advisory committee.
The operators were satisfied with the results presented to the advisory committee and urged the businesses to continue to work on their respective lines and work together to leverage the benefits of the new equipment and design tools showcased.
Although this marks the end of the NEOSUB project, the companies involved have all emerged with strengthened vision and perspectives to continue the research work they undertook with this project.
