New clarification added: Answered by previously posted clarification on 3 September 2019.

New clarification added: Question: P4b) Conduct all equipment installation (field preparatory work, ground movements and other hand-work tasks shall be done by the CEAC technical team), integration and testing of the hybrid system, including the BESS (procured by the vendor) and the equipment already installed in the power station.Question#13: Is the foundation and grounding of the equipment covered by CEAC? Or CEAC is only responsible for leveling the land, and the bidder need to consider the budget of foundation and grounding of ESS.Answer#13:As stated CEAC can provide field preparatory work, ground movements and other hand-work. Foundation and grounding is the responsibility of the bidderP5The installation, commissioning and CEAC personnel training shall start after the equipment shipment and approximately on the 3rd quarter of 2019. The duration of these activities shall last no more than 20 working days from the start. The hybrid power plant shall be fully operational from the 30th of November 2019.Question#14: Does the construction period of 20 days include transportation time?Answer#14:The Construction period does not include transportation duration. It start from the final delivery at CEAC site. Once again as clarified for question #5, the timeline of full operation is to be by the end of April 2020.  P7 AC/AC overall efficiency shall be minimum 80%.Question#15: How to define AC/AC over efficiency? Such as evaluation method, evaluation duration.Answer#15:AC/AC overall efficiency is a round-trip efficiency – an efficiency of a single charge and discharge cycle - measured on an AC-to-AC basis. Thus, it is assumed that the battery has its own AC-DC inverter.  AC/AC round-trip efficiency includes losses due to power conversion from AC to DC and back to AC, the energy storage cells, busbars, battery management systems and thermal management systems. If there is no a dedicated AC-DC inverter for the BESS and the BESS is connected to the DC power line of solar PV, then apply the losses of the shared AC-DC inverter for Solar PV and BESS, which have to be a part of the bid offer.P8The diesel generator(s) and the synchronized bank shall be capable to charge the BESS.Question#16: What does “the synchronized bank” mean? Please kindly clarify?Answer#16:It means that the synchronized generators set (multiple generators in synchronized mode = “the synchronized bank”) have to be capable to charge the BESS. P8 Spinning reserve: Guarantee optimum loading and spinning reserve of diesel generators.Question#17: Please specify how much spinning reserve is required?Answer#17:The demanded spinning reserve should be defined by the bidder from the load profile Att D3 - CEAC Load 24 hours forecast 2020- scaled x2 May 2018 v0.2.csv which gives load demand as kW=f(t). Please take it with PF=0.8. Thus, the theoretical spinning reserve [kVA] is the MAX(load profile)[kW] / 0.8 for the case that full load can be backed up exclusively by diesel generators without Solar PV and BESS support. In practice it would mean to run so many generators synchronized, that their nominal capacity in kVA would be above this level. Currently, there are FG Wilson P300H-1 and P150-3 installed, and there is a plan to install additional P300H-1 and P150-3. It is a bidder’s duty to configure proper spinning reserve profiles for current and future generator setups.P17UL1741 Standard for interconnecting distributed resources with electric power systems (Inverters, Converters, Controllers and Interconnection System Equipment for Use with Distributed Energy Resources) (for PCS) or equivalent IEC 62477-1:2012 or equivalent Electronic equipment..... Question#18: Both UL1741 and IEC62477 is concerning safety requirement of power electronic converter system. Is it acceptable THAT the selected PCS only meet certification requirement of IEC62477?Answer#18:Yes, it is acceptable that Power Converting System (PCS) has at least one certification of the following standards or their equivalents UL1741 • UL62109 - UL62109-1 General - UL62109-2 Inverter specific • CSA C22.2 No. 107.1 • CSA 62109 • IEC 62109-1 • IEC 62109-2 • IEC 62477 what ever applicable to the specific PCS type and ensure a safe operation of the device.

New clarification added: P2The system shall be capable of integrating as a minimum the following components and operational features: 1. 4 Diesel Generators (sizes range 150-500 kVA three phases 60 Hz) 2. Diesel Generator synchronization system 3. Solar PV arrays (up to 200 kWp of installed power and up to 40 inverters)Question#9: We need to know the communication protocols of these products so that BESS can control and manage them.Answer#9:Currently, the P300H-1 has control panel PowerWizard 1.1; P150-3 has the control panel FG Wilson DCP-10; the installed Sunny Boy Inverters are communicating via RS485 to the SMA WebBox with Ethernet port and Modbus TCP protocol (see more details at SMA portal). The bidder has to provide the solution which should enable the diesel generator synchronization and their operation with the BESS. Thus, the control panels for generators have to be replaced within the bid scope. The bidder defines the communication protocol for generators. According to the CEAC upgrade plan, it is foreseen to enlarge PV array and install more SMA Sunny Boy-6.0 inverters with Ethernet/Speedwire/WebConnect ports; the SMA WebBox will be replaced with SMA Data Manager M. It is a bidder’s duty to provide a solution to support both current and future inverters communication protocols or offer a replacement which in this case have to be included into the bid.  P2The system shall be capable of integrating as a minimum the following components and operational features:1. 4 Diesel Generators (sizes range 150-500 kVA three phases 60 Hz) 2. Diesel Generator synchronization system 3. Solar PV arrays (up to 200 kWp of installed power and up to 40 inverters) 4. Energy Smart meters for customer billing and tariff control Item 4: Energy smart meters for customer billing and tariff control.Question#10: Does it mean we need to provide smart meters and billing system? Answer#10:No, the bidder doesn’t have to provide smart meters and billing system for customers. However, it is a bidder duty to ensure that the Hybrid controller, BESS, synchronization control panels for generators have meters to allow the monitoring energy production coming from various source (PV, Genset, Batteries…) and all parameters necessary for safe operation of the equipment. P2The system shall be capable of integrating as a minimum the following components and operational features:1. 4 Diesel Generators (sizes range 150-500 kVA three phases 60 Hz) 2. Diesel Generator synchronization system 3. Solar PV arrays (up to 200 kWp of installed power and up to 40 inverters) 4. Energy Smart meters for customer billing and tariff control 5. Power transformers for step up LV-MV for power transmission 6. Power generation 24 hours / 7 days a week.Question#11: How to define power generation 24 hours /7 days a week, and what is the technical index to evaluate it?Answer#11:There are 3 load profiles for the whole year (8760 hours), namely for 15 hours/day; 24 hours/day in 2019, forecast 24 hours/day in 2020 are attached to the initial bid materials:·         Att D1 - CEAC Load 15 hours May 2018 actual v0.csv·         Att D2 - CEAC Load 24 hours forecast 2019- not scaled May 2018 v0.1.csv·         Att D3 - CEAC Load 24 hours forecast 2020- scaled x2 May 2018 v0.2.csv P3Thus, the proposals might be submitted for 4 lots: the combinations of 2 storage technologies and 2 remaining BESS capacity after 4,000 cycles.Question#12: There are three battery containers in the planned layout (Att A2). However, it is required to provide 4 lots in the financial proposal. Please clarify. Does it mean that the final capacity is still uncertain?​Answer#12: The 3 containers in the plan are just to show the available place to install the BESS and do not reflect any technical design or capacity; and as clarified for question #4, there is another place next to the 313 KVA generator that can receive the installation as long as the system can fit in the available space (30ft x 28ft marge included). The tender requests to submit 4 independent “lots” (proposals). All lots are evaluated separately, but only 1 lot will be nominated for an award: compliant with all requirements and having highest score which fits budget upper threshold.

New clarification added: Question#4: Do you have electrical drawings of the gensets? Including electrical wiring, grounding and references of existing protection circuit breakers.Answer#4: The connection of both installed FG Wilson generators is similar and presented in the sketch attached. There is no electrical drawing available.
