Increasing population creates the need for sustainable and continuous energy supply. Traditional transmission and distribution grids have been witnessing significant transformation. The transformation is primarily fueled by the integration of technological advancements, such as data analytics, smart sensors and automation, for a smarter grid with improved grid security and grid reliability. Apart from the digitization of the grid, scientific advancements in material science contribute to the growing need for off-shore deployment of renewable power. Increased research focus is witnessed in developing reliable and cost-effective foundation structures for off-shore wind power installations. Self-healing materials have the potential to improve the safety of off-shore wind turbines.
