About How much does it cost to connect wind power to the grid
The typical cost of grid interconnection for tying a wind or solar project into the power grid is $100-300/kW or $3-10/kW-km of distance.
The typical cost of grid interconnection for tying a wind or solar project into the power grid is $100-300/kW or $3-10/kW-km of distance.
The cost of grid interconnection has averaged $138/kW across 3,382 projects in the database, which breaks down as $51/kW for thermal power plants, $138/kW for wind projects and $167/kW for solar projects. As a rule of thumb, 25% of the cost is direct cost, while 75% is the requirement to fund network upgrades, per our note here.
Wind turbines account for 64% to 84% of total installed costs onshore, with grid connection costs, construction costs, and other costs making up the balance. O shore wind farms are more expensive and cost USD 4 000 to USD 4 500/kW, with the wind turbines accounting for 44% to 50% of the total cost.
Recent reports released by the Lawrence Berkeley National Laboratory (LBNL) highlight how high interconnection costs—which refer to the costs associated with interconnecting an energy generator or storage project to the grid, including investments at the point of interconnection and any broader network upgrades needed to accommodate the .
There are good incentives for the sale of excess electricity or for the purchase of wind turbines. Federal regulations (specifically, the Public Utility Regulatory Policies Act of 1978, or PURPA) require utilities to connect with and purchase power from small wind energy systems.

6 FAQs about [How much does it cost to connect wind power to the grid]
How much does a wind turbine cost?
Even more so when you factor in taxes, government incentives, and tariffs. Large wind turbines built for onshore and offshore wind farms can generate about 2 to 3 MW, while the largest offshore turbines can generate up to 12 MW of electricity. Needless to say, they’re expensive. While costs can vary, they generally hover around $1 million per MW.
What is the difference between grid connection and construction costs?
Grid connection costs include cabling, substations and buildings. The construction costs include transportation and installation of wind turbine and tower, construction wind turbine foundation (tower), and building roads and other related infrastructure required for installation of wind turbines.
How much would a 100-megawatt wind farm cost?
In 2018, EDP North America, a renewable energy developer, proposed a 100-megawatt wind farm in southwestern Minnesota, estimating it would have to spend $10 million connecting to the grid. But after the grid operator completed its analysis, EDP learned the upgrades would cost $80 million. It canceled the project.
What are the capital costs of a wind power project?
The capital costs of a wind power project can be broken down into the following major categories: Source: Blanco, 2009. Wind turbine costs includes the turbine production, transportation and installation of the turbine. Grid connection costs include cabling, substations and buildings.
How much does a grid connection cost?
A grid connection is not available or can only be made through an expensive extension. The cost of running a power line to a remote site to connect with the utility grid can be prohibitive, ranging from $15,000 to more than $50,000 per mile, depending on terrain.
How much does a 12 MW wind turbine cost?
The most powerful 12 MW wind turbine costs up to $400 million to manufacture and install. Costs for utility-scale wind turbines can be broken down into three categories: manufacturing, transport and installation, and operations and maintenance. Researchers are constantly working to drive down the costs.
