Getting a new house? Lucky you! Or perhaps you are just going back 'on the grid'. Either way getting power to your house is not always as simple as connecting up a line.
There are two ways to get power:
1. Get a transformer on your property (substantial cost involved here)
2. Tap into an existing transformer. For this to happen, there needs to be capacity on that transformer for your requirements, and you need to get permission from the owner of the property.
Often the cheapest way of getting power to a new section is to go to the nearest transformer. The owner of the land has likely paid for the installation of the transformer and may want to use the excess capacity in it for their own future subdivision, should they wish to do so. If your neighbour refuses access to the land they are within their right to do so.
In this case you will need to go down the path of getting your own transformer.
PowerCo owns the transformers, but not the property that they are on. They can give you authorisation for you to use the transformer, but not access to the land.
So it pays to be on good terms with your neighbour as the cost of getting power could be more if you have to pay for your own transformer.
