Technical FAQs 4

What's going on with the wind power industry?

The wind power industry is facing major cost headwinds. What's going on (and what can be done)? Wind power forms a significant part of the projected expansion in renewable energy sources. This article was first published in October 2023 and updated in November 2023. Soaring costs are forcing some wind power developers to delay or halt new projects.

Is onshore wind the cheapest way to produce electricity?

In countries such as Estonia and Spain, onshore wind is now among the cheapest ways to produce electricity, with levelized costs reported as low as €24–€50 per MWh – cheaper than most fossil alternatives. Crucially, it’s not just about cost – it’s about investment and return.

How much does onshore wind cost?

O&M (operations and maintenance) costs for onshore wind are relatively low (~€10–€20 per MWh produced in many cases), but for a homeowner that could mean occasional servicing fees. For large farms, maintenance is often around 20–25% of the total cost of energy over the project life.

Should wind farms add energy storage?

Adding energy storage (batteries) can help store excess wind power and sell it when prices are higher, improving project economics. Some wind farms are adding batteries to provide grid services (like frequency regulation) – an extra revenue stream.
