Demolition of the wind turbine within the overall structure, including the foundation, tower, cabin and leaves. After re-rating the site and retired, re-upgrade the new fan and achieve grid.
"80-20" renovation method: replace the fan cabin with the leaves, keep the fan tower and foundation.
Technical transformation: to retain the cabin, but the replacement of multiple parts within the cabin. Technical changes may replace the leaves, and the replacement of the blade often need to replace the other parts of the cabin, such as generators, due to the replacement of longer leaves and need to replace more power generation capacity of the generator.
The traditional refurbishment method refers to the removal of the entire fan and replace the new models, including the fan base, tower, cabin, leaves, usually also include power plant facilities. Due to the large number of fans hoisted in 1990 before the high wind speed area, California is the traditional renovation of the current major market.
In contrast, MAKE on the current PTC policy under the "80-20" renovation method that the cabin is the main components of fan power generation. Therefore, if the engine room as a whole to replace the fan that is refurbished and its installed capacity into the corresponding manufacturer's market share. According to the "80-20" refurbishment method, the foundation of the non-power generating parts and the tower can be kept constant or improved according to the actual situation.
Selective replacement or upgrades to spare parts within the cabin are not retrofitted and are technically the most common way to deal with older fans with lower FMVs and which require fewer parts to meet PTC requirements. The installed capacity of the technical transformation is not included in the manufacturer's market share statistics in the year or in the future. In addition to special circumstances, MAKE in the database statistics and research analysis, through the technical transformation of the project is not part of the new lifting capacity.
In some cases, after the technical changes to the fan components, the fan rated power may be increased or the impeller diameter increases. This will be considered as the first time after the project put into operation, stand-alone capacity increase or decrease to deal with: installed capacity changes will not be included in the fan manufacturer annual additional capacity statistics, but MAKE will upgrade the existing hoisting project database , MAKE market outlook will also update the cumulative capacity, reflecting the changes in technological transformation projects.
