What if BigWind is successful, right now, in persuading Ohio legislators to change the 1,125 foot setback that keeps an industrial wind turbine away from your property? You could have a 400 foot turbine that is switched out for a 700-1000 foot turbine. This brings more noise, infrasound vibrations, longer ice throws, shadowing, etc…and there will be absolutely nothing you can do to stop it. BigWind loves to tell the public that their machines generate energy for 20 years, but the truth is below. Operating and maintenance issues plague the turbines by 12 years and they could be outdated well before 10 years. The industry is pushing Ohio legislators to make a setback change NOW in the next budget. When is the last time YOU took a few minutes to contact your legislator?….
…Turbine technology has evolved rapidly in the last five years, and the turbines of today bear little resemblance to the technology installed 10, 15 or 20 years ago.
That aging fleet, combined with the production tax credit (PTC) extension, is driving owners and operators to move to capture the PTC value for another 10 years on their existing assets, and reap the cost savings and revenue benefits of repowering their projects.
What are advantages of repowering?
With stable PTC production revenue, it makes sense for owners to invest in upgrades that will keep their turbines operating reliably for the next 10 years or possibly beyond.
At the same time, owners benefit from reduced operation and maintenance (O&M) costs of as much as 40% since older technology is more expensive to repair…
What types of repowering solutions are available?
The right repowering solution depends on the age of the fleet and the owner’s priorities. Depending on the solution, owners can reap AEP improvements of 10% to 40% while driving down O&M costs by as much as 40%.
Refurbishing, or selectively replacing components, is well suited for highly depreciated projects where replacing only a few components will satisfy the four times fair market value spend threshold.
Repowering the nacelle and rotor, which is ideal for turbines at or near their 10-year PTC expiration, is best suited for projects where the new nacelle and rotor will deliver significantly higher AEP or address chronic reliability issues.
And finally, full repowering, or replacing older generations of turbines with substantially larger new technology, can be the optimal solution for plants at or near their end of life. Repowering with new turbines delivers dramatic AEP increases and eliminates the reliability and supply chain headaches associated with running obsolete turbines…
