Enercon is offering new operating modes for its E-175 EP5 E1 turbine that can raise annual energy production by as much as 5%, depending on site conditions.
The manufacturer said the upgrades, available for new and existing machines, are based on prototype testing and form part of its strategy to optimise turbine performance throughout the lifecycle.
Head of product management Moritz Rodenhausen said: “We continuously work to improve the performance and yield characteristics of our products. With our dynamic performance upgrades, we ensure optimal turbine operation throughout its entire lifecycle and offer our customers significant added value in all operational phases.”
Enhancements include a noise-reduced mode, which can deliver about 5% higher output, and improvements to the yield-optimised mode that reduce sound power levels by 1dB while enabling a power increase to 6.3MW.
EP5 product manager Timo Müller said: “If there are no grid-related restrictions, many more wind farms can now switch to the yield optimised mode and benefit from the power increase to 6.3MW – and thus significantly higher yields. That’s real added value.”
Enercon said the upgrades require hardware and software changes but do not alter the turbines’ operational lifetime. Previously available modes remain valid.
The company first introduced optional operation modes for the E-175 EP5 in 2023 and said further upgrades are part of its long-term product strategy.
