Field crew training in the energy sector: what Spanish law requires and how to keep records per crew

 

Field crew training in the energy sector is proven by checking that every crew sent out on a work order has, on that same day, valid training for the tasks it is going to carry out. A certificate per person filed in a folder doesn't answer that question.

Field crew training in the energy sector has a problem that the same company's offices don't: the risk is spread across wind farms, substations and power lines, and much of it falls on people who don't work for the utility. In Spain in 2024, electricity supply companies recorded 850.5 lost-time accidents per 100,000 workers. In specialised construction, where installation contractors sit, the figure was 5,776.3: roughly 6.8 times higher.¹

The two figures don't measure exactly the same thing. The energy division, which employed 45,066 people in 2023,² includes retail, operations and office staff. But the gap points to something every maintenance manager will recognise: the riskiest field work is usually done by contractors' staff, organised in crews that change members and locations every week.

In this article we cover what Spanish regulations require from people working on grids, substations, wind and solar, why training records break down when crews move around, and how to set up a per-crew record that answers the question that really matters: can this team do this job today?

 

What Spanish regulations require for field crew training in the energy sector

 

There is no single regulation that says "this is the training a field technician needs". The obligation is built in layers, and each layer has its own renewal period.

The foundation is Spain's Occupational Risk Prevention Act (Ley 31/1995). Article 19 requires training that is "theoretical and practical, sufficient and appropriate", focused on each person's job or role. It has to be given on hiring and again whenever roles change or new equipment is introduced. It must take place during working hours, at no cost to the worker, and be repeated periodically where needed.³

On top of that base come the risk-specific rules. Electrical risk has its own framework, with the roles of authorised and qualified worker, which we explain in detail in our article on electrical risk training. Rope access work at height, common on wind turbines and towers, requires specific training covering seven subjects, including fall arrest systems and rescue techniques for people suspended in a harness. The regulation sets no hours or renewal period.⁴

For many installation and maintenance companies there is a third layer: Spain's 4th National Collective Agreement for the Metal Sector, which expressly covers the installation, maintenance and repair of power generation and distribution facilities.⁵ The agreement sets 20 hours of in-person trade training (12 common and 8 specific). It has dedicated content for power lines and electrical equipment and for solar and wind installations, and requires a 4-hour refresher every 4 years.

Wind adds a private standard: the Global Wind Organisation (GWO) Basic Safety Training. It is not a legal requirement, but it is usually demanded by contract before anyone climbs a turbine. Its modules cover first aid, manual handling, fire awareness and working at height, plus sea survival offshore. Training records are checked in the WINDA database.⁶

 

 

One detail usually goes unnoticed. Article 23 of the Prevention Act lists the documents a company must keep available for the labour authority, and training is not on that list.³ The metal sector agreement does require a system to accredit it, preferably through the sector's Professional Card.⁵ In practice, the record is the only way to show that Article 19 was met.

Spain's Prevention Act does not include training in its list of mandatory documents, but without a record per person and per task there is no way to prove that Article 19 was met.

 

Why training records break down in field crews

 

A classic training record is organised by person or by course. In an office, that works. In the field it fails for four reasons.

 

Reason 1: the crew changes faster than the record

 

The crew heading to the substation on Monday is not the one going to the wind farm on Thursday. On-call shifts, holidays, reinforcements and technicians switching areas all come into play. A per-person record says what each individual has done, but it doesn't say who is going out today or whether that combination covers the task.

 

Reason 2: part of the crew works for another company

 

In wind and solar maintenance it is common for a crew to mix in-house staff and contractors. Contractors' training lives in their own systems, on the metal sector card or in WINDA. Those sources accredit courses, but they are not your record: they don't know which work order you've assigned or which procedure you changed this month.

 

Reason 3: site information doesn't travel with the person

 

Royal Decree 171/2004 requires the site owner to inform contractors about the site's own risks before work starts, and in writing if those risks are serious or very serious. Each contractor must then pass that information on to its people.⁷ In reality, this usually ends up as a signed sheet in a wind farm's site hut. When a technician moves to another site, that training doesn't carry over, and nobody notices until an audit comes along.

 

Reason 4: every accreditation expires on its own clock

 

A technician from a wind contractor can be juggling three different deadlines: GWO modules at 24 months, the collective agreement refresher at 4 years and the construction site card, which expires after 5 years.⁵ ⁶ In a three-person crew that's nine dates, and by default none of them line up. A spreadsheet with a "course date" column won't flag any of them.

 

The crew clearance record: how to keep training records for every field team

 

The crew clearance record cross-references three things: who is going out, to which site and for which tasks. Unlike an individual's file, it answers a single operational question: is this crew cleared for this work order today? We build it in five steps.

 

Step 1: list field tasks, not job titles

 

A "maintenance technician" may carry out switching operations in a substation, climb into a nacelle or clean solar panels. Each of those tasks calls for different training. That's why the inventory is built by task, and each task is linked to the layers in the table above: which regulation, agreement or standard applies.

 

Step 2: match each person to the tasks they can do

 

With the inventory in place, build a person-by-task matrix that also includes contractors' staff. If the task involves electrical risk, the cell depends on the written authorisation granted by the company, not just on the course. If you cross-check with the metal sector card or WINDA, the matrix records the data, but the decision to clear someone is still yours.

 

Step 3: give every cell an expiry date

 

Expiry goes on each person-task combination, not on the course. That way, when a working-at-height module expires, only the tasks that need it are blocked. It's worth setting alerts two months ahead: the GWO standard allows renewal up to two months before expiry while keeping the original certification date.⁶ We cover the fields each record needs in our guide to building a multi-standard training record.

 

Step 4: check the record when assigning the work order

 

The time to look at the record is when the work order is assigned, not when the inspector arrives. Whoever plans the work checks that every task on the order has at least one cleared person, and that nobody will carry out a task with an expired cell. If a cell fails, you change the person or change the date, and the decision is logged.

 

Step 5: add the site and the procedure version

 

The last two columns of the record are the site risk information (who received it and when) and the procedure version each person was trained on. When a procedure changes, the record flags who is missing the new version.

At that point, the bottleneck is usually preparing the updated module for every crew at once. It's the kind of work that custom training tools like Vidext prepare with AI agents from the procedure itself: the module waits for your approval and, once completed, leaves a completion record for each person.

 

Crew record example: corrective maintenance at a wind farm

 

Picture a work order to replace a component in a wind turbine nacelle, scheduled for early November. A three-person crew goes out: two in-house technicians and one from a maintenance contractor. Names and dates are illustrative.

 

 

Read this way, the record shows three problems before anyone climbs the tower:

• Iván is within the two-month window to renew his working-at-height module without losing the original date.
• Marcos hasn't received the risk information for this wind farm and was trained on an earlier version of the lifting procedure.
• Nobody from the contractor is authorised for electrical risk, so any electrical operation on the order falls to Laura or Iván.

With a per-person record, all three facts exist, but in three different places. The crew record brings them together at the only moment they can still be fixed.

 

Conclusion: in the field, training is checked crew by crew

 

Energy sector regulations don't ask for a per-crew record, but the way field work is organised makes one almost unavoidable. The law sets the obligation per person. Risk-specific rules and the collective agreement add content and deadlines. And standards like GWO's bring their own expiry dates.

What ties all those layers together is the work order. A company that checks training when it assigns the order can fix gaps in time. One that checks when the audit arrives can only explain why something was missing. With crews that change every week, the training that counts is the training that is valid on the day the crew goes out.

 

Frequently asked questions about field crew training in the energy sector

 

What mandatory training do field staff at an energy company in Spain need?

 

At a minimum, the prevention training required by Article 19 of Ley 31/1995, focused on their job and tasks. If they work with electrical risk, the training under RD 614/2001. If they work at height with ropes, the training in annex II of RD 1215/1997. Installation and maintenance companies covered by the metal sector agreement must add the 20-hour trade training and its refresher. It's worth reviewing with your prevention service which layers apply to each task.

 

How do you keep training records for crews working at different locations?

 

By organising the record by task and by work order, not only by person. A crew record cross-references who is going out, to which site and for which tasks, along with the expiry date of each training and the procedure version. It is checked when the order is assigned, which is when you can still swap someone out.

 

Is GWO training mandatory to work at a wind farm?

 

It is not a legal requirement in Spain: it is a private wind industry standard. Even so, it is usually required by contract to access turbines, and it does not replace the training required by the Prevention Act or the regulations on work at height.

 

How often is the safety refresher required under the metal sector agreement?

 

The 4th Metal Sector Agreement sets a 4-hour refresher every 4 years. It is also required when a person has been out of the sector for at least one continuous year. The Construction Professional Card for the metal sector expires 5 years after it is issued.

 

Who trains contractor staff working at a substation?

 

Job-specific training is the responsibility of their own employer. The substation owner must inform the contractor about the site's risks and give instructions before work starts (in writing if the risks are serious or very serious), and the contractor must pass that information on to its workers. That's why the crew record logs both items separately.

 

What tools help train field technicians in the energy sector?

 

The ones that work in the field have three things in common: they let you prepare and update short modules when a procedure changes, they keep a completion record by person and version, and they connect with the training system the company already uses. Before choosing, check whether the tool can include contractors' staff and not just your own.
