6 FAQs about [The latest dispatching regulations for energy storage power stations]
When does priority dispatch no longer apply to power generating facilities?
Article 12(6) states that priority dispatch shall no longer apply to power generating facilities from the date on which such facilities are subject to significant modifications where a new connection agreement is required or where the generation capacity of the power generating facility is increased.
Which units will retain priority dispatch under Article 12?
As discussed in Section 3.1, under Article 12, there will be units in the SEM which retain priority dispatch under existing legislation and new units which would have previously qualified for priority dispatch such as renewable energy generators and high efficiency co-generation along with conventional generators. These are summarised in Table 4.
What is Article 13 (5) of the electricity regulation?
Article 13 (5) of the Electricity Regulation refers to the capability of TSOs and DSOs to transmit electricity from renewable energy sources with minimum possible redispatching, which should not exceed 5% of the annual generated electricity in installations which use renewable energy sources.
What does Article 13(5)(a) of the new electricity regulation mean?
Under Article 13(5)(a) of the new Electricity Regulation, TSOs and DSOs are required to guarantee the capability of transmission networks and distribution networks to transmit electricity produced from renewable energy sources or high-efficiency cogeneration with minimum possible redispatching.
What does the new electricity regulation mean for power plants?
Under the new Electricity Regulation, this is defined as the dispatch of power plants on the basis of criteria which are different from the economic order of bids, and from network constraints, giving priority to the dispatch of particular generation technologies.
When will priority dispatch units be scheduled first?
Where there is excessive generation to meet demand, priority dispatch units will be scheduled first, subject to system security considerations. In the case of excessive generation, dispatch down of other units will be required based on economic merit order (accounting for operational and system security considerations).
