上网电价补贴（英语：FIT, Feed-In Tariff或Standard Offer Contract），也被称为强制性上网电价补贴、可再生能源回购电价、保护性分类电价制度或者政府电力收购制度，是一项旨在加速推进可再生能源广泛应用的政策机制。政府与使用可再生能源发电的个人或公司签订一份20年的长期合约，期间发电者每向公共电网输送一度电，除了获得原本的电价以外，还可以赚取若干补贴。

这种补贴的金额由政府公布，一般取决于当时此种能源发电设施的造价及安装费用。因此造价高的能源补助也高，比如，对风能的补贴相对于太阳能光伏和潮汐能来说就要少一些。 上网电价补贴的金额通常随着时间流逝、各种能源技术的提高、成本的下降而逐年减少。

A feed-in tariff (FIT, standard offer contract) advanced renewable tariff or renewable energy payments is a policy mechanism designed to accelerate investment in renewable energy technologies. It achieves this by offering long-term contracts to renewable energy producers, typically based on the cost of generation of each technology. Rather than pay an equal amount for energy, however generated, technologies such as wind power, for instance, are awarded a lower per-kWh price, while technologies such as solar PV and tidal power are offered a higher price, reflecting costs that are higher at the moment.
