Abstract

Recently there has been a significant debate about the possible implementation of a centralized capacity mechanism in Poland. Despite the fact that capacity adequacy is currently being discussed at the national level as a long-term issue, the lack of sufficient capacity and insufficient demand flexibility has already been observed on a number of occasions. In July 2016, the Polish Ministry of Energy expressed its support for the implementation of a market-wide capacity mechanisms. In view of these recent events, the aim of this paper is to shed some light on the possible implementation of a capacity market in Poland. The paper presents a brief overview of the key problems that the Polish power sector faces and provides a comparative analysis between some of the main elements of the Polish capacity market proposal and the GB capacity market.

Abstract

The paper investigates the supply structure of the capacity market in Poland in the coming years. The results of the capacity auctions conducted in 2018 are analyzed for this purpose. Three auctions were held at that time. The products traded in the capacity market are capacity obligations for the following years: 2021, 2022 and 2023. The auctions were organized in accordance with (i) he Act of December 8, 2017 on the Capacity Market and the (ii) Capacity Market Regulations published by the Polish Power Grid. The source of data used in this study is the official information of the President of the Energy Regulatory Office on the final results of the main auctions for 2021–2023 delivery periods. The list of the capacity suppliers who won capacity auctions contains the type of capacity market units, the volume of capacity obligations, the duration of capacity agreements and the business name of the capacity suppliers. The conducted analysis indicates that the auction for 2021 was won mainly by existing units (45.81%) and refurbishing units (33.51%). In subsequent years, the share of existing generating units is significantly higher and amounts to 91.67% for 2022 and 84.54% for 2023. The results of the study carried out in this paper also show that one energy company, being the owner of power generating daughter companies, has a very high share in these capacity auctions. The PGE Capital Group contracted 51.95% for 2021, 69.92% for 2022 and 64.44% for 2023 of the total capacity obligation. The volume amounts to over 70% of their total installed capacity.
