G99 Application

Hi all,

Bit of a hot topic this, but who is responsible for making a G99 application? Does it lay with the PD, as they have now submitted their Stage 4 designs, and specified the load and generator sizing. if so why?

Or does it lay with the installer, if so why? The PD is pushing it back onto the contractor.

Thanks

Heera

  • I agree with Mike. This is ultimately the responsibility of the generator (being the legal entity that owns the grid connection) i.e. the customer, and it will always be their signature on the connection agreement.

    It's very common on retrofit C&I projects for the installer to take on the role of agent / installer on the customer's behalf, because for many projects they are the ones with the knowledge that it needs doing, how to do it and what information needs to go into it. Most installers will offer to manage it (not least because it gives them control of that part of the project, which does make their life somewhat easier, and often it scores brownie points during the sales process by providing a turnkey solution) and many customers assume that it's the installer's role as a result.

    But it's also not unheard of for G99 to have been dealt with by the developer, particularly for new builds where generation really ought to have been considered alongside any other loads when requesting the supply. After all, as Mike says, it can represent a considerable risk to the project until consent is secured. That developer might then split out particular roles, such as instructing contestable works by an ICP while a generator installer does the commissioning notifications, as they contract out the works.

    I suggest everyone checks their contracts. If it doesn't say anywhere then it's probably for the Client to take on, and perhaps pass down as a variation.

    However, if you're the installer, it's not normally hugely difficult to manage the process and as long as the risk of any reinforcement costs or delays (etc) don't fall on you probably less expensive than any delays due to an uninformed customer getting it wrong.
