Slide 31: Conclusions (1)
Conclusions (1) No clear ‘trend’ with respect to: - Sourcing method: o Tenders, mandatory services, bilateral negotiations are all used to procure restoration services o Interesting: use a tender or bilateral negotiations depending on the situation (the need for a black start unit, the amount of com
Slide 32: Conclusions (2)
Conclusions (2) Clear ‘trend’ with respect to: - Number of restoration service providers: o Amount and geographic distribution of service providers seems comparable (or higher) than in Belgium. o Often more than one provider in the same zone Benchmark indicates a risk averse strategy at TSO side w
Slide 33: Conclusions (3)
Conclusions (3) With respect to type of providers: - Production types: o Conventional thermal plants and pump-storage units o Several examples of HVDC (contracted or owned/ full service or back-up) o Some cases with smaller plants (hydro or gas turbines): cascade effect, used to start up larger unit
