Why Combined Courses Make Logistical and Financial Sense
Key Takeaway / TL;DR
If you’re a wind-technician or wind-operations manager, bundling the certifications – for example Global Wind Organisation (GWO) Control of Hazardous Energies (CoHE) plus NFPA 70E electrical safety, or the GWO Advanced Rescue Training refresher (ARTR) with Basic Safety Training Refresher (BSTR) – means fewer days in training, less travel/off-site cost, and streamlined compliance with both OSHA and GWO standards. At STL USA we deliver these combined courses that save you time and money, as well as an administrative headache while maintaining top safety benchmarks.
1. Efficiency in days and dollars
By combining courses you reduce redundant modules, travel and downtime. For example, our onsite training packages allow you to take CoHE + NFPA 70E in one streamlined block, rather than scheduling separate sessions. See more about our onsite feature.
Similarly, bundling the GWO ART refresher (ARTR) with the Basic Safety Training Refresher (BSTR) means your technicians don’t need to travel twice, thereby saving on per-person overhead.
2. Meeting multiple standards at once
-
The CoHE course covers hazardous energy control in wind turbines (mechanical, hydraulic, electrical) and is offered by STL USA under the GWO accreditation.
-
NFPA 70E addresses low and high voltage electrical safety, which aligns with OSHA electrical safety requirements. By training both together you meet OSHA expectations and renewable industry protocols in one shot.
-
The ARTR + BSTR combo helps maintain GWO certifications (which must be refreshed every two years) and ensures technicians are up to date on rescue and safety modules in one cohesive block.
3. Real-world savings & case study
At STL USA we’ve trained over 4,000 technicians across wind farms in the United States, working with major clients such as RWE, Siemens Gamesa and Pattern Energy.
For one client, we combined a CoHE + NFPA 70E block onsite, eliminating travel for 20 technicians, saving roughly 40 overnight stays and reducing lost production hours by approx. 10 %.
We routinely see onsite mobile training units reduce cost per technician by 20-30% compared to separate off-site programmes.
How to Choose the Right Bundle for Your Workforce
-
Assess what needs renewing – Identify which certifications your team has due for refresh (BSTR, ARTR, CoHE, NFPA 70E).
-
Consider your site logistics – On-site training at the turbine farm removes transit costs; a mobile unit from STL USA can come to you.
-
Map training modules to business risk – If you have lots of electrical work, the CoHE + NFPA bundle is optimal. If you’re focused on rescue readiness, ART + BSTR is better.
-
Select the strongest provider – STL USA has world-class facilities in Abilene, Texas (tower, mock-ups, technical workshop) and significant wind-industry experience.
-
Budget & schedule accordingly – Bundled training reduces days away from production. For example:
-
CoHE + NFPA session: ~2-3 days vs separate 4-5 days.
-
ARTR + BSTR refresher: 4 days instead of 6.
-
Bundled Course Options at STL USA
-
CoHE + NFPA 70E: Combine hazard energy control modules with electrical safety.
See our CoHE page and NFPA 70E electrical course. -
ARTR + BSTR: For technicians who have completed core safety training and need both rescue and safety refresher. See GWO Advanced Rescue (ART) and Basic Safety Training Refresher.
-
On-site Custom Bundles: Training delivered at your site for maximum efficiency (mobile training unit).
Frequently Asked Questions (FAQ)
Q: What is the advantage of bundling CoHE + NFPA 70E?
A: It reduces separate training events, saves travel/time, meets both mechanical/hydraulic and electrical safety standards, and ensures you’re aligned with OSHA as well as GWO/NFPA requirements.
Q: Can I still take the ART refresher and BSTR separately?
A: Yes – but by bundling you save cost and downtime by consolidating modules, and only one mobilisation of your team.
Q: Will combining modules affect certification validity?
A: No. Each module remains valid on its own; bundling doesn’t reduce validity—it simply delivers both together. At STL USA we maintain compliance with GWO refresher intervals (every 2 yrs) and NFPA standards.
Q: How many technicians can participate in an onsite bundle?
A: The mobile training unit and onsite delivery model allows for groups of technicians, scaled per site. Contact STL USA for minimum numbers and scheduling.
Q: Are there additional cost savings beyond training days?
A: Yes. On-site delivery reduces travel/accommodation, lost production due to technician downtime, and administrative overhead for multiple bookings.
Final Thoughts
In today’s fast-moving wind energy sector, every hour your technicians spend off-site is an hour of potential productivity lost. By choosing a bundled training strategy with STL USA, you’re aligning safety compliance (OSHA, NFPA 70E, GWO) with operational efficiency. You’re reducing cost, reducing downtime, and building a workforce that’s both certified and ready to deliver
