Surprisingly, the common questions I get about wind turbines, are usually about what regulations or laws exist for installation and siting etc.
This is a difficult question to answer in specifics as each local power authority has different guidelines that need to be properly investigated before a plan to install a wind turbine can begin.
For example, in some rural areas, the feed lines to properties are relatively small with lower system voltages (7200V is common for rural areas, as is 14,400V). The transformers on these lines are designed to handle a certain amount of current to customer locations, and weren’t designed for feeding power back into the grid.
Luckily, if your customer is one of only a few in an area, even with a 50kW system it shouldn’t be a large concern, as the amount of energy created by the turbine system even at peak production would likely be consumed by all of the neighbouring properties on that feeder line before it would be fed back through substations into the grid.
Conversely, in an area that is quite attractive to wind power, many customers may be interested in installing systems. Having 20 or 30 turbines on a single feeder line may not be allowed by the local power authority, as during peak wind conditions, 30 x 20kW turbines would be trying to feed approximately 600kW of power back on a feeder line that may only be rated and capable of 500kW maximum.
Additionally, some local governments even have regulations requiring fences to be constructed around wind turbine bases and other very specific rules pertaining to installation. All these types of information can only be completed and investigated by proper leg-work, typically on the part of a local dealer. It is crucial for the dealer to obtain contact information for the local power authority and to collect information on their regulations and permitting processes before each installation can begin. Furthermore, when you work closely with the local government and municipalities, installations run more smoothly and quickly, making it a painless process.
