Generation minimum cost calculator 

1. Costs on this page are from the generator standard charges document published by the CRU.
2. Costs shown are non-contestable costs. With non-contestable being works that are solely carried by the ESB and the CRU�s estimation of what these costs would be.
3. This cost sheet is intended to be used for connections to the DSO network greater than 200kW.
4. The price shown is combined from the essential items required depending on the MW's applied for and the connecting voltage level.
5. For connection less than 1MW, an MV bay price will be included. If teeing to an existing demand line this price will not be required. If teeing into an existing generations line a per MW share of the bay will be paid as a refund.
6. If any items are shared with another generator, they will be shared on a per MW basis. This can be done during construction or if the asset is already built, the next generators to connect will pay a portion of any shared assets.
7. Following a more detailed study additional costs may arise:
8. Protection items. (A protection study would identify what is required on the network
9. Uprate works (Any item with capacity issues that is required to be replaced)
10. Pass through items (Any additional costs associated with work not covered by the CRU standard charges)
11. Transmission system operator (TSO)
12. Unforeseen costs such as but not limited to rail, road, river crossing, land access, existing infrastructure, built-up areas, ground conditions / geotechnical issues of conservation etc.
13. These costs will only be identified at the earliest when a full study has been carried out.
14. If a transformer is shown to be overloaded on the generation capacity heatmap then additional transformer uprate costs that match the issue can be taken from the commonly used uprate items and added to the minimum cost found on this page.
15. All caveats associated with the heatmap also apply when using with the cost calculator.
16. The cable civils costs are included with the minimum estimation. This work is always completed by the applicant and is only included here to show the difference in cost between cable and overhead line.

This minimum cost calculator provides an estimation of the minimum costs associated with generator connections to the distribution system operator (DSO) network >200kW.

• It will not provide the final amount that will be offered to a customer as a detailed study will always be required to identify any potential other costs.
• The costs shown are the minimum base costs associated with each type of project. After a detailed study, pass through costs (costs not available in the standard charges), transmission system operator (TSO) costs, protection costs, potential uprate costs and any other charges will be identified and added to the costs shown on the minimum cost calculator.
• For connections less than 1MW, an MV bay price will be included.
• If teeing into an existing demand line this price will not be required. If teeing into an existing generations line, a per-megawatt (MW) share of the bay will be paid as a refund. It is unlikely that a connection >1MW would tee into an existing demand line.
• If any items are shared with another generator, they will be shared on a per MW basis. This can be done during construction, or if the asset is already built, the next generators to connect will pay a portion of any shared assets.
• This calculator is intended to be used with the generator capacity heat map. If uprates are found on the heatmap then a cost guide of standard charges located at the bottom of the calculator can be used to find the additional costs.
• Not all costs may be covered with the generator standard charge and some additional costs may still be required.
