Increased knowledge in this topic can be used to evaluate the feasibility of e.g. energy storage, local electricity production, and flexibility, or if grid extensions might be the only solution. Extending the grid is however costly in terms of capital and time, thus alternatives that may increase the grid usage effectiveness should be sought firsthand.
