The efficiency and availability improvements lead to up to 7 % increase in capacity factor, which directly impacts the annual energy production. The marked improvements in reliability lead to 11 % reduction in O&M costs. Consequently, the levelized cost of energy decreases by up to 7 % with respect to the existing design.
