Interconnection of national electricity grids into regional power pools is an option that might, for example, allow the sharing of the highly efficient hydropower production of one country while at the same time greatly enhancing stability of supply for all interconnected countries.
例如，各国电网相互连接，形成区域电力联合，这也许可以分享一国进行的高效能水电力生产，同时大大地促进相互连接的各国供应的稳定。
