1. Introduction Target
The introduction target uses the term introduction, but this case is not limited to completed offshore wind projects; in calculating the 2030 and 2040 figures, the target includes projects that are planned and have received recognition by the government. This fact has potential for misunderstanding among parties involved. Achieving this target alone will not make a meaningful contribution to the attainment of the goal of 46% reduction in greenhouse gas emissions by 2030; additional measures will be required to put the various projects formed into operation as early as possible.
2. Japan Content Target
Japan content refers to the percent of domestically procured products and services across the entire wind-power generation lifecycle; the target is set at achieving 60% Japan content. Some media mistakenly reported that the target aims to achieve domestic manufacture of 60% of the parts of wind turbines. However, the scope of this target goes beyond manufacturing to include products and services throughout the entire wind-power project life cycle such as: surveys, manufacturing, construction, operation, maintenance, and decomissioning. Manufacturing involves cost optimization of the supply chain on a global level, and the same applies to offshore wind turbines. Misconceptions that this target aims to increase domestic procurement in manufacturing alone threaten to disrupt the current, optimized supply chain.
3. Cost Reduction Target
The vision lacks a clear definition of power-generation costs (LCOE). Wider government discourse on power-generation cost implies that this target refers to the cost of energy; this differs from other definitions such as tender price, which takes into account fair profits for operators on top of the cost of energy itself.
These considerations must be taken into account when assessing progress toward the targets, and all discussion should be based on the correct understanding and accurate definitions.
