当今水电发展受限于水能资源，在原有基础上再考虑蓄能蓄电可利用电网低谷剩余电能储存转换，变成和再生能源一样，可周而复始更新使用，形成各种电源持续发展的循环机制。蓄能蓄电涵盖抽水蓄能和其他蓄能蓄电设施后，特别有利于节能减排和可再生新能源的发展。今后应关注风险分析、风险设计和风险管理。

Now the exploitation of waterpower is limited by its water and hydropower resources. The power net will be short in peak and surplus in valley. Supplementing pump storage plant into the ordinary hydropower, the surplus valley power can be changed into the precious peak power. By this kind of expectation the surplus power may be renewable and is favorable to the sustainable development. As the storage measures included, the hydropower is favorable to the sustainable development of the various energies, including nuclear & wind etc renewable energy. Hydropower is an important supplement to the environment. We have to pay great attention to the risk analysis, risk design and risk management. The difficult problems are discussed.
