Lehtirova wind farm
The Lehtirova wind farm project has been a significant strategic step for Empower in the Swedish market and has strengthened the longstanding cooperation between OX2 and Empower in wind power construction.
Empower is one of the main contractors in the wind power company OX2’s Lehtirova wind farm. The 41-turbine wind farm is located in Pajala and Gällivare in Northern Sweden. The wind farm will be completed by the end of 2018 and its annual electricity generation is estimated to be at 490 GWh per year, which is roughly equivalent to the annual electricity consumption of 98,000 households.
Empower has designed and constructed the road lines, crane hardstands, foundation bottom structures and foundations required for the wind farm’s 41 wind turbines. Empower has also been responsible for the safety planning and route guidance of the entire worksite. The wind farm was the biggest wind farm project in Empower’s portfolio by 2017 and the first one in the targeted Swedish market. The Lehtirova wind farm project is large already on the basis of the number of wind turbines but the longer distances in the park make it a particularly large project.
Empower started earthworks in October 2016, continuing through the winter. In April 2017, Empower began to construct the wind turbine foundations. A long and snowy winter brought some challenges to the start of foundation casting. However, by adjusting the casting rhythm, the schedule could be maintained. Casting continued actively throughout the summer, all the way to late autumn when the foundations of the last wind turbine were completed.
Empower achieved all the schedule-related objectives set for 2017 and kept up with the monthly forecasts, thanks to the skilled personnel and careful preparation: in addition to a project plan, Empower’s experts prepared risk and contingency plans regarding the most critical parts of the project.
OX2 has been pleased with the cooperation with Empower.
– Empower has always dealt with questions or problems in a very professional manner and everything has gone as planned and according to schedule. I recommend Empower for future OX2 projects, too, says Björn Olofsson, Construction Project Manager at OX2.
The cooperation with the other contractors at the worksite has also proceeded in a good and constructive spirit.
