Aside from reducing costs, avoiding the need to increase generation capacity with more power plants, and more pipelines and electricity transmission and distribution lines helps avoid the range of problems that come with building big energy infrastructure, such as NIMBYism (Not In My Back-Yard syndrome). In most countries it can be a very difficult and lengthy process to obtain planning for large pieces of infrastructure like power plants. The opportunity costs associated with planning and commissioning energy infrastructure are high and are best avoided if possible.
