Tenders Are Invited For Inverters – Acquisition Of 31 Mw/62 Mwh Energy Storage in Hungary

Work Detail

Inverters – Acquisition Of 31 Mw/62 Mwh Energy Storage. Within The Framework Of The Tisza Amfora Project, A New Battery Energy Storage Unit (Bess) Is Being Built In The Mvm Tisza Power Plant. The New Bess Is Connected To The 15.75 Kv Transformer Of Block 2 Of The Tisza Power Plant Via A Newly Installed 15.75 And 0.4 Kv Distribution Container (Not Part Of This Public Procurement Procedure). The Task Of The Successful Tenderer Is The Complete Design, Delivery, Installation, Procurement Of Spare Parts And The 11-Year Warranty Period Of The Energy Storage Unit With A Power Of At Least 31 Mw And A Storage Capacity Of At Least 62 Mwh (Beginning Of Life), Which Can Be Connected At 15.75 Kv Performance Of Preventive Maintenance Tasks Under The Winning Tenderer Is Also Responsible For The Complete Technical Adjustment And Commissioning Of The Installed System, Documentation And Archiving Of Commissioning Materials And Software Configurations. The Mavir Accreditation Of The Power Plant Will Be Conducted As Part Of The Trial Operation. The Task Of The Contractor Is To Prepare And Implement The Test Operation, And In Particular To Conduct The Mavir Accreditation. The Energy Storage To Be Delivered Is A Battery Energy Storage Unit That Is Suitable For The Service Of Frequency And Power Equalization Products (Afrr, Mfrr, Etc.). The Blocks Of The Energy Storage Unit Must Contain At Least The Following Equipment And Systems: - Planned 20 Dc/Ac Two-Way Converter(S), - Planned 1 Matching Transformer(S) Per Block, - Planned 2 Air Conditioning Units Per Block, - Internal Energy Supply System, - Planned 20 Bms (Battery Management System) Management System And Its Communication Tools, Management Software, And Their Licenses To Foreign Systems. The Energy Storage Must Have A Comprehensive Management And Data Processing System That Can Be Controlled Remotely. During The Entire Period Of Its Operation, It Collects And Stores The Quantity And Quality Data Specified In The Technical Description (Point 4.11) About Its Operation, For Later Evaluation. The Energy Storage Installation Units (Through One Or More Converter Voltage / 15.75 Kv Matching Transformers) Are Connected To A Newly Installed 15.75 Kv Distributor, Which Will Be Installed In The Immediate Vicinity Of The Energy Storage Units. The Total System Efficiency Of The Energy Storage Unit, Projected Over One Charge-Discharge Cycle And Measured At The 15.75 Kv Transfer Point, Should Be At Least 86.5% Including The Self-Consumption Of The System. When Determining The Efficiency, Iec62933-2-1 Standard 5.2.3. The Formula Marked For Figure 2 In The Roundtrip Efficiency Subsection Must Be Taken Into Account. The Winning Tenderer Is Also Responsible For Conducting The 720-Hour Trial Operation As Detailed In The Draft Contract. The Tenderer Also Draws Attention To Clause 8.12 Of The Draft Contract. To Carry Out The Warranty Measurements Specified In Point Related Services: - Provision Of Remote Monitoring. - Preventive Maintenance Required To Ensure Warranty Conditions
