Perkupa 22 kV Substation Energy Storage

LOT-0001
EKR002151632024/1
Perkupa 22 kV Substation energy storage.
The contractor's delivery scope includes the acquisition, assembly, transportation to the site, installation, testing, and commissioning of a complete 5 MW/10 MWh capacity electrical energy storage unit with a 0.4 kV connection. The contractor is also responsible for performing regular maintenance, troubleshooting in case of failures, and conducting group training on the basic operation and management of the energy storage, which must be held for 20 people over 2 working days, 5 working hours per day, before completion. Another task is to operate the equipment. The energy storage must be delivered with a centralized remote monitoring device. The control of the energy storage will be managed by a higher-level energy management system (EMS), and it is the contractor's responsibility to integrate the energy storage into the EMS. The contracting authority will provide the existing permits and licensing documentation to the winning bidder. The preparation of the necessary execution plan documentation for the installation of the energy storage – if the contractor deviates from the issued electrical execution plan – is the responsibility of the winning bidder, which must be reviewed and approved by the contracting authority before starting the execution. Detailed specifications are included in the technical description and draft contract. Delivery scope: The complete battery energy storage equipment, including: batteries, inverters/converters, auxiliary operational units, cooling-heating, ventilation system, protection systems, including secondary surge protection (T1+T2), fire protection equipment, local control technology, communication, and Hungarian language user interfaces. Delivery and installation on the foundation. Ensure all machinery necessary for placing it on the foundation. Installation and assembly of the equipment. On-site commissioning of the equipment. Comprehensive assurance of information for connecting and configuring related infrastructure (EMS). Testing of related infrastructure. On-site acceptance inspection (review documentation, initial trial operation report, manual operation test). The contractor must ensure security of the area until handover, with special attention to quality control, quality assurance, occupational safety, and health protection. The contractor is responsible for the removal of waste generated during the work included in the scope. Description of the equipment to be supplied: The contractor must deliver a turnkey energy storage system to the contracting authority, whose key components include: the inverters/converters that perform energy conversion and can operate in a 4-quarter range, the batteries, the system providing auxiliary operation, the protective equipment, including asset and fire protection equipment, the Central Control along with necessary hardware, the necessary operational software, and associated licenses. Modes to be implemented: Off-grid mode, Standby mode, 22 kV grid voltage regulation, Reactive power compensation, Line load balancing, Management of network capacities. Each mode must operate within the storage capacity, safety, and protection limits. The possibility of free switching between feasible modes must be ensured through the control system. Battery: The main goal of implementing the energy storage is to improve and maintain network stability, taking into account the highest environmental and life safety considerations. Therefore, only tested and proven technologies may be offered. Battery technologies prescribed by the contracting authority: Li-Ion based technology (e.g., NMC, LFP, or other lithium-ion chemical compositions) or other energy storage technology that is evidenced as equivalent from technical and economic perspectives and meets the grid connection, safety, local conditions, and operational requirements (the applicability of the technology must be justified). Battery DoD requirement (DoD, Depth of Discharge (%)) Required value: > 80% Within 28 calendar days after commissioning, the contractor must support with measurement documentation. The nominal storage capacity of the battery energy storage (kWh) BoL (Beginning of Life) value must be before the handover! To be validated by re-measurement post-installation! The measurement must be conducted on the AC sides of the energy storage KIF (inverter outgoing AC terminals) without auxiliary operating equipment, regarding the removable value on the AC side. Requirement: ≥ 10000 kWh Estimated EoL capacity: ≥ 8 100 kWh Nominal DC system capacity: ≥ 5 184 kW (BoL) Round Trip Efficiency: ≥ 93% Lifespan (80% DoD): ≥ 10 years or until achieving 5000 cycles for performance warranty (70% SOH) The exact subject of the procurement and the tasks of the bidder will be detailed in the technical description chapter of the complementary procurement documents of the call for proposals and in the draft contract.
