从传统上讲，电力的输送是从大型集中的发电厂通过集中的输电网向本地分配系统供电。但是，在大部分欧洲国家里，这种方式将不再占据主导地位，分布式发电和可再生能源发电已经日益渗透进入这些主要网络。这也为开发新型发电工艺（例如太阳能、风能和水能）提供了良好的前景。

Traditionally, the delivery of power has been based on large, centralized power plants supplying electricity to local distribution systems through an intensive transmission network. This process is not dominant anymore, however, and the penetration of distributed generation {DG） and electricity from renewable energy sources into these mains networks is increasing in most European countries. This offers high hopes for the development of emerging new generation technologies such as solar, wind or hydrogen.
