Ensuring adequate European market and system methodologies
European energy regulations in many cases provide for the clarification of specific solutions by means of methodologies created by TSOs and NEMOs, and the approval of National Regulatory Authorities (NRA) or the European Agency for the Cooperation of Regulators (ACER). Since, in many cases, regulations are created at a very general level, these are the methodologies that determine the actual shape and quality of many power engineering solutions. Properly prepared methodologies are, therefore, crucial for market processes and other TSO activities; they have a direct impact on the quality of solutions, costs for individual entities and countries, and security of electricity supply. Therefore, PSE's active participation in the preparation of the methodologies and their approval process by the relevant regulatory authorities is crucial for the quality of the market and power system solutions implemented.
PSE employees take an active part in the work of teams developing methodologies at the European and regional level to ensure the high quality of the solutions developed and, therefore, the efficient operation of the market and the power system at the national and European level.
Ensuring adequate stock levels
The main task of the Operation Department's (DE) storage management is to ensure that adequate storage reserves are available in the event of an emergency. In order to determine the quantities of each type of devices and materials, the DE has developed a normative document. This document, which is updated periodically, indicates which stocks are sensitive to PSE in the event of an emergency.
The Operation Department’s stock management is the responsibility of the Devices and Materials Reserve Operator (ORUiM), which, through its ongoing activities, fulfils its obligation to keep DE stock at an appropriate level. The stock is replenished through targeted purchases made by ORUiM, devices and materials from investment tasks (new, constituting a reserve in accordance with the provisions of the ToR), and devices and materials from dismantling as part of operational, repair and modernisation tasks.
In pursuit of the objective of ensuring adequate stock levels, ORUiM prepares tender procedures that result in contracts for the supply of devices and materials indicated in the normative document. As the Operation Department is unable to predict when a failure will occur and what devices will be affected, contracts are usually for a period of three years where possible, allowing purchases to be made based on DE's actual needs. Where such contracts are not available, one-off purchases are made to replenish stock. A timetable of procurement procedures has been developed for the period 2022–2030.
