The energy transition is one of the largest global challenges of our time. A key aspect is replacing fossil fuels as primary energy sources with renewable energy sources such as solar and wind energy. The consequences of this radical change will be an accelerated electrification of society.
Electricity will become a backbone of a multi-energy system with natural gas, hydrogen and heat as additional useful energy carriers. Several large-scale power plants will generate the electricity, and will be joined at a fast-growing pace by many small-scale distributed sources. The variable nature of renewable energy sources, forms a challenge for energy supply security and stability, and the transition will therefore have an unprecedented impact on the design and operation of the power grid, amplified further by the electrification of transport, heat and industry sectors.
