The central solution used by wind farm owners and operators globally to manage lightning risk effectively.
Supporting over 5300+ wind turbines across 20 countries worldwide.
Lightning Monitoring Solution
No physical sensors, no installation, no hassle.
LASSIE is an online subscription service, delivering 24/7 automated lightning surveillance with no hardware installation required. No sensors, no on-site equipment, nothing to maintain. Pairing global lightning detection networks with blade-specific knowledge and IEC 61400-24 compliance verification.
We turn the uncertainty that follows every lightning storm into a clear, structured decision framework, so you know exactly what to inspect and what to skip.
No installation required
Get the data you need without any hardware installation required on site. Less hassle and easier long term maintenance.
Faster Warranty
Receive instant alerts showing exactly which turbines need inspection. Technicians upload inspection photos directly into the platform, creating a permanent digital logbook.
Stronger Insurance Case
Build stronger technical evidence to connect lightning event and turbine damage. Establish causation, not just correlation.
How It Works
LASSIE uses an extensive global network of ground-based sensors to track lightning activity around wind farms.
By combining this data with our IEC‑compliant methodology and in‑house expertise, LASSIE identifies which turbines are likely to have been struck – and exactly when. This is crucial for an effective blade lifetime management, and helps build stronger warranty and insurance cases.
Who Is This For?
Our lightning surveillance service offers the insurance market and wind farm owners & operators major cost savings due to early detection of potential lightning damages, avoiding unnecessary labour, material, and rental cost.
No you do not need permission thanks to LASSIE’s network system and lack of on-site hardware installation.
No. LASSIE’s automated workflow enables early damage detection and provides the documentation insurers require to demonstrate prudent management, without installing or maintaining hardware.
Yes, LASSIE’s automated workflow is designed to do the work for you. Simply onboard your wind turbines and receive tailored alerts based on probability, distance, turbine model, and lightning characteristics, with historical data identifying turbines most exposed since their last inspection.

Proactive Responses
Trigger Service Agreement blade inspection to mitigate risk of catastrophic blade failures.
Case Study
Situation
59 wind turbines are placed under LASSIE Surveillance. The wind farm owner has full access to their wind farm historical lightning data and a dedicated dashboard for lightning data insights.
Complication
51 out of 59 turbines are hit by lightning over a 3-month period, resulting in 10 damages and a 80% LPS efficiency rate. Only 10 turbines require action.
Solution
As a result of LASSIE, 6 structural defects were identified, which would have progressed over time. The proactive inspections prevent significant repair and maintenance costs.
Proven return on investment with major utility scale wind farm owners and operators.
Significant cost savings in excess of 40% can be seen in the instance where LASSIE solutions are used because repairs are detected earlier than otherwise expected.
Mitigate forseeable lightning damage risks
Lightning strikes to a wind turbine blade can create severe damages, even with a lightning protection system (LPS) installed. Early detection and precise root cause analysis lead to cost-effective repairs and maintenance, optimizing operational expenditure (OPEX).
Avoid Complications
Response time to lightning strikes is crucial to avoid catastrophic blade failure. Within a short time frame, the damage can cause a blade to collapse or fail, creating major complications.
Regular and thorough blade assessments help in extending the lifespan of wind turbine blades, ensuring better return on investment (ROI).
In collaboration with Weather Sentry, LASSIE helps users to create custom alert ranges to mitigate any lightning risk for the ground crew.
