tuulivoimalan

Tuulivoimalan is the Finnish term for a wind power plant or wind farm, a facility that converts wind energy into electricity using wind turbines. A typical installation comprises multiple wind turbine units, a collector system, and electrical infrastructure that links the generated power to the electric grid. Each turbine consists of a rotor attached to a nacelle mounted on a tall tower; blades capture kinetic energy and transfer it to a generator inside the nacelle. The electricity produced is stepped up in voltage by transformers and routed through substations and cables to the grid.

Wind farms can be built onshore or offshore. Onshore facilities are usually easier and cheaper to install but may be subject to land-use constraints and local opposition. Offshore wind farms access steadier and stronger winds but require more complex foundations, subsea cables, and higher maintenance costs. The size of projects ranges from small clusters to hundreds of megawatts of capacity.

Output depends on wind conditions; capacity factor varies by site and turbine technology. The electricity is intermittent and must be integrated with power systems and, increasingly, with storage or flexible generation to maintain grid stability. Environmental impacts are generally lower in operation than fossil fuel plants but include visual and noise effects, land use, and potential effects on birds, bats, or marine ecosystems. Decommissioning involves removing equipment and restoring sites.

Economically, wind power has seen substantial cost reductions and attracts investment through policy support, auctions, or feed-in tariffs. Typical wind projects have lifetimes of 20–25 years and require ongoing maintenance and monitoring.
