"As a measure to foster decentralised renewable energy deployment, in early 2018, Chile reformed its Distributed Generation Law (also referred to as the “Net Billing” Law). The reform included a tripling of installed capacity threshold from 100 kW to 300 kW, which aims to support and promote larger projects of self-consumption of electricity. As in the original law, electricity surplus can be fed into the grid to obtain discounts in the owner’s electricity bill. The reform establishes, that if an owner has more than one establishment, these discounts are also applicable for those electricity bills, otherwise, discounts from surplus can be accumulated."
