The wind turbine business ought to anticipate round two catastrophic fireplace incidents at a median wind farm in the course of the lifecycle of a wind turbine.

That’s the standout statistic from a brand new report from Firetrace International, a supplier of fireplace suppression programs for the wind business.

In “The Complete Guide to Wind Turbine Fire Protection”, Firetrace explores the price and good thing about managing this danger – offering wind turbine homeowners, operators, and their insurers with an evaluation of the chance of fires, common price of a hearth loss, and the price of safety utilizing a number of fireplace suppression programs.

According to a number one supplier of insurance coverage providers for renewable vitality tasks, over a 7-year interval, the common loss per fireplace incident is $four.5 million – a determine set to extend with the enlargement of bigger, extra superior generators.

Most turbine fires originate within the nacelle, making it troublesome to combat as a result of vital well being and security danger of sending a group as much as extinguish the hearth.

If not instantly suppressed, fires that start within the nacelle result in the overall destruction of the turbine and might doubtlessly unfold into the encircling setting – incurring not solely monetary losses, however reputational injury to the proprietor or operator, and the business as an entire.

In order to scale back the severity of nacelle fires, automated fireplace suppression programs have to be put in at the details of ignition – converter and capacitor cupboards, the nacelle brake, and the transformer.

A system designed with versatile Detection Tubing is simpler in these fireplace suppression programs. Once a hearth breaks out, this tubing ruptures and a suppression agent is launched mechanically via the tubing or through diffuser nozzles nearest to the purpose the place probably the most warmth is detected, extinguishing the hearth exactly the place it begins and earlier than it might take maintain.

Even after accounting for the chance of a hearth, as soon as a turbine’s capability exceeds 3MW, the price of fireplace suppression to guard all three danger areas is outweighed by the price of changing that turbine. Installation of fireplace suppression programs in any respect three ignition sources usually prices lower than $30,000 – lower than 1% of the common set up price of a 3MW onshore wind turbine and fewer than zero.6% of the common price of a hearth loss.

The Firetrace information consists of sensible recommendation and proposals for funding into fireplace suppression programs primarily based on turbine measurement and price.

Angela Krcmar, Senior Business Development Manager, Firetrace stated: “The unintended penalties of a hearth incident in a wind turbine can have far reaching operational, security and well being dangers. While preventative expertise akin to arc flash detection and situation monitoring programs can scale back the chance of a hearth, solely suppression programs can put a hearth out as soon as it has began.

“If homeowners, operators, and insurers need to assure a hearth is proscribed to the nacelle, fairly than spreading down the tower, to different generators, and doubtlessly into the encircling setting, investing in a suppression system is essential. Suppression programs could be put in throughout manufacture, or retroactively fitted to generators at low price – giving homeowners and insurers peace of thoughts that their turbine can proceed to function safely.”
