📋 Tender Overview
Contract awarded for 72.5 kv blue gis - installations lot-0000, title: 72.5 kv blue gis - installations, description: alliander n.v. intends to conclude a framework agreement with siemens energy b.v. through the negotiation procedure without announcement based on article 3.36 paragraph 1 sub c under 2 of the public procurement act 2012 for the supply of 72.5 kv blue gis installations. market research by alliander has shown that siemens energy b.v. is the only party capable of supplying the installations that meet alliander's requirements and specifications. alliander intends to realize five (5) new substations. to this end, it intends to purchase five (5) gis switch installations. alliander has several locations available where it intends to place the new substations. these substations are scheduled for realization after january 1, 2028. the selection of the locations for these substations took place before the entry into force of the f-gases regulation. the dimensions of switch installations of the sf6-containing type were taken into account. expansion of the locations is not possible. therefore, it can only purchase switch installations that fit within the dimensions of these locations. maximum dimensions (wxdxh) per field are: • busbar: 800 x 4250 x 2870 mm • transformer bay (50 kv transformer): 800 x 4470 x 2600 mm • transformer bay (150/110 kv transformer): 800 x 5275 x 2870 mm • cable bay: 800 x 4470 x 2600 mm • busbar coupling bay: 800 x 3650 x 2600 mm expanding the locations is not possible. furthermore, alliander requires a nominal rail current of 3150a and 40 karms / 3 s short-circuit strength. under the european f-gases regulation, it is generally not allowed for alliander to put sf6-containing installations into operation with a voltage level from 52 kv to 145 kv after january 1, 2028. for this reason, alliander has formulated the following requirement that the insulation and extinguishing medium used in the switch installation must meet: 'gas mixtures with gwp =1 and vacuum (sf6 gas and pfas are not permitted)'. exclusion of the use of pfas-containing gas (in particular c4fn) is made for the following reasons that justify this choice individually and collectively: 1. minimization obligation regarding the release of very concerned substances (zzs), including pfas. 2. duty of care for personnel. alliander has a duty of care throughout the entire lifespan of its switch installations. pfas-containing gases are known to pose irreversible health risks. moreover, switch installations are not completely leak-proof. alliander does not want to expose its personnel to these risks. 3. environmental protection. pfas-containing gases are known to pose irreversible risks to nature. alliander does not want to cause unnecessary harm to the environment. 4. uniformity. alliander currently has no pfas-containing installations in use, which means that its personnel would need to be specifically trained and certified for the entire lifespan of such installations. a potential future ban would lead to inefficiency in training and deployment of personnel due to the parallel operation of multiple systems. alliander wishes to have as much uniformity in its installations as possible and to fully focus on future-proof choices. 5. uncertainty about long-term availability. the installations have a lifespan of at least 40 years, which can practically extend to 60 years and, in the event of leakage, must be refilled with gas. the availability of pfas-containing gases is uncertain in the long term, which could significantly shorten the lifespan of the installations. 6. insufficient research on c4fn. c4fn is a relatively newly developed gas that has not been sufficiently researched yet. independent and dependent studies do not yet provide a clear result. alliander does not want to use technology whose risks have not been sufficiently mapped. insulating media with gwp =1 and vacuum (without sf6 and pfas) provide the certainty that these aforementioned risks for the environment and health are not present. there is also no ban on this technology, which ensures that installations based on this technology can be maintained throughout their entire lifespan. in the long term, standardization of switches in the electricity grid is an important principle. due to rapidly developing regulations, this technology is the most future-proof. no reasonable alternative or substitute alliander has conducted market research which showed that there are no other parties than siemens that can meet all the aforementioned requirements. the vt blue gis is the only installation that meets all the requirements and fits in size within the locations that alliander has available to realize new stations. for alternative installations that meet the other requirements, at least 25% more space would be required. purchasing additional space is not possible. objection if you have objections to the intended award of the contract to siemens, or believe that the aforementioned award has incorrectly invoked an exception, you can express your objections by initiating summary proceedings within twenty (20) calendar days after the date of this publication. if this does not happen, the agreement described above can be established, and such objections can no longer lead to the annulment (cancellation) of the agreement. estimated value excluding vat: none .72.5 kv blue gis - installations
