净计量电价（英语：Net Metering）是一项电力政策，该政策使拥有可再生能源发电设施的消费者可以根据向电网输送的电量，从自己的电费账单上扣除一部分，也就是只计算“净消费”。净计量电价一般用于用户端的小型发电设施，如风能、太阳能光伏、家用燃料电池、V2G电动车等。

如今欧美地区所使用的电表，绝大多数都可以进行双向计量，因此采取净计量的方式基本上没有额外的成本。 因此，净计量电价与上网电价补贴政策以及智能电表的应用不同，它不需要提前签订合约，改换设备（欧美而言），是一种简单易行的计量方式。

Net metering (or net energy metering, NEM) allows consumers which generate some or all of their own electricity to use that electricity anytime, instead of when it is generated. This is particularly important with wind and solar, which are non-dispatchable. Monthly net metering allows consumers to use solar power generated during the day at night, or wind from a windy day later in the month. Annual net metering rolls over a net kilowatt credit to the following month, allowing solar power that was generated in July to be used in December, or wind power from March in August.
