Poland's long-debated Renewable Energy Act was adopted in February 2015. After going through two amendments, the new law became effective in July 2016. The Law substitutes an auction system for the green certificate system. The first auction was held on December 30, 2016, and the results were released in early January 2017. Additional auctions were held in the spring of 2017, and more were planned for the summer and the fall. The Act was unclear about whether combining an auction contract with other forms of public funding would violate the EU's standards on fair competition, therefore the final two 2017 auction rounds were annulled. These errors served as the impetus for the following revision to the Act, which became effective on June 29, 2018. The auction system was amended by the June 2018 legislation, which also effectively unblocked it. To add new renewable energy capacity to the system, the Energy Regulatory Office (URE) of Poland is required to plan and conduct auction rounds by the end of 2018 and early 2019. Auction technology baskets were updated by the June 2018 modification.
