Supplier Post #22 - Site Inspection This post is publicly visible

Hi,

We understand a site inspection was previously scheduled and cancelled but due to the easing of covid lockdown circumstances changing in Victoria can a request for an independant site visit be made and if so who can we schedule this with?

Thanks

Posted on 23 June 2021 22:01 by Supplier Person

Thanks for the inquiry.  The project is unable to accommodate an independent site visit prior to the RFT Closing Time.

As a result of the non-compulsory site visit being cancelled due to covid restrictions, and to assist Tenderers, the Project uploaded additional drone footage and images to TendersVIC.  Refer to document numbers 14, 15 & 18.

Tenderers may specify any assumptions/exclusions relating to site conditions in their Tender as part of Returnable Schedule 6b.

Supplier Post #21 - BESS sizing This post is publicly visible

For the BESS sizing does the load peak at 70kW or is it a continous load of 70kW?

Posted on 23 June 2021 16:15 by Supplier Person

The BESS must be able to provide both charging and discharging at a continuous rate of 70kW.

Supplier Post #20 - Compliant BESS size clarification This post is publicly visible

Hi there,

We are seeking clarification on our interpretation of compliant BESS sizing.

The tender advertises a 250kWh nominal capacity battery, which, reading the general specification (clause 8.3) we understand to be the nominal rating that "shall" be achieved at the end of the battery life (i.e. factoring degradation this will not be the initial nominal capacity). Clause 8.6 of the general specification requires batteries to have a minimum design life of 10 years.

With the above in mind, can you confirm our interpretation is correct - that a compliant BESS solution will be rated at 250kWh nominal capacity (at minimum) 10 years after installation?

Posted on 18 June 2021 13:30 by Supplier Person

Tenderers may assume degradation to provide a nominal capacity of 80% at the 10 year point, which equates to oversizing the BESS by 25%.

Tenderers can provide manufacturer documentation as part of their submission to confirm that degradation rates of their proposed system in its installed context will be lower (better) than this, then the oversizing can be reduced correspondingly.

Supplier Post #19 -  Local Industry Development Plan (LIDP) This post is publicly visible

The LJF Policy applies to standard projects above the threshold values of:

  1.  $1 million or more in regional Victoria, or
  2.  $3 million or more in metropolitan Melbourne.

As the project value do not meet the threshold , Is it still considered as standard project (point 3)?

 

details to be kept confidential  please.

Thanks for your request for clarification.

The Local Jobs First Policy is applied at the project value, rather than the estimated value of an individual procurement package.

Supplier Post #18 - Lightning Protection This post is publicly visible

Hi there,

We have performed an AS/NZS 1768 risk calculation in preparing our compliant solution, but we'd like to know if GMW has any specific LPS (i.e., type I, II, III, IV) requirements at this site - especially if those would exceed 1768 principles/guidance?

Thanks in advance.

Preference for my details to be kept confidential

Posted on 17 June 2021 19:12 by Supplier Person

As a guide:

  • Tenderers should make allowance for surge diverters to ensure all electrical, control and instrumentation equipment shall be protected against surges and transients imposed on the signal and power lines and antennae by lightning or electrical switching.
  • Tenderers should make allowance to provide any necessary additional protective device(s) to ensure that the Calculated Risk is lower than the Acceptable Risk for all loss categories in accordance with AS/NZS 1768.  The acceptable risk levels will be agreed with GMW during the detailed design phase.
  • Tenderers can outline the measures proposed in Returnable Schedule 4
