Prolonged lifetime and an increased overall revenue by retrofitting ageing wind turbines
Controller retrofit increases power productivity by 2%
Calculations based on qualified data
Besides having improved its turbines’ AEP, Terra-Gen also benefits from improved availability and free data access. The retrofitted turbines are available for monitoring 24-7 to secure production and the increased access to qualified turbine data has enabled Terra-Gen to make a thorough analysis and calculate the business potential.
Throughout the whole process, DEIF’s team of experts from Denmark and Austria has been at Terra-Gen’s disposal 24/7, meaning that questions and uncertainties have been handled right away, making the process progress efficiently
"Our team works closely together with DEIF, and through 24/7 monitoring, we get data that we have not been able to get from our old setup. This enables us to ensure a better maintenance strategy which again saves us both work and money."
"We strive to run our turbines efficiently – at the lowest cost. The Pacific Crest Wind Farm is a high wind site, and the cost of downtime is critical. So, having reduced downtime and increased productivity with 2% in only six months tells me that we were right to go with DEIF."
Performance optimization & lifetime extension
The increased demand for competitive power production and the rapid development in the wind industry necessitates that older turbine models such as the Vestas V47 are equipped to meet today’s performance standards. DEIF’s control retrofit solution extends the turbine lifetime and optimizes the turbine performance in terms of variable speed concepts, extended cut-out and Adaptive Power Output. The results from the Pacific Crest site are so convincing that Terra-Gen considers replacing obsolete VRCC units with DEIF’s control solution on all its turbines.
Can I help you?
"This project is a class example of a partnership, and cooperating with the Terra-Gen team at Pacific Crest has been a true pleasure. Both teams have been chasing the same goal, and succeeded in the best possible way. Validation and monitoring have proved that we are on the right track, and we are looking forward to continuing the cooperation with Terra-Gen and partners."
