Renewable Energy Asset Protection and Workforce Services
Corrosion protection and HR services for wind farms, solar installations, and other renewable energy infrastructure.
What drives complexity in this sector
As the renewables sector expands across Southeast Asia, the need for specialist asset protection and qualified workforce solutions is growing rapidly. JST Group supports renewable energy developers and operators with proven cathodic protection, protective coating, and HR services adapted for this evolving sector.
Foundation Corrosion
Offshore wind and solar foundations face aggressive marine and atmospheric corrosion, demanding robust coating and CP systems from day one.
How we solve it: Foundation CorrosionRemote Site Operations
Renewable energy projects are often built in remote locations requiring specialised logistics, workforce deployment, and on-site technical support.
How we solve it: Remote Site OperationsEvolving Standards
The regulatory and technical standards for renewables asset protection are rapidly evolving, requiring partners with current knowledge and flexibility.
How we solve it: Evolving StandardsSpecialised Talent
The renewables sector competes intensely for experienced construction, commissioning, and operations personnel across Southeast Asia.

Renewables
Where corrosion starts in Renewables assets, and how we stop it
The asset groups that corrode first, the mechanism behind each, and the JST service that addresses it. Compiled by our Corrosion Control Division from survey and maintenance work across the region.
- 01
Monopiles, jackets and transition pieces
How we solve it: Monopiles, jackets and transition piecesThe threat Sea water, the splash zone and sealed internal compartments with oxygen-depleted water corrode foundation steel over a 25-year design life.
How we protect it Galvanic and impressed current CP for foundations, internal compartment CP and coating repair.
- 02
Tower internals and nacelles
How we solve it: Tower internals and nacellesThe threat Humid, enclosed air corrodes bolts, flanges and electrical cabinets, particularly after transport and during commissioning delays.
How we protect it Vapour-phase inhibitor emitters in cabinets, Air IQ monitoring of enclosed spaces and preservation during storage.
- 03
Solar mounting structures and cable trays
How we solve it: Solar mounting structures and cable traysThe threat Galvanised steel and aluminium in coastal or industrial atmospheres suffer galvanic and crevice corrosion at fixings.
How we protect it Materials review, coating specification and isolation at dissimilar-metal joints.
- 04
Substations and switchgear rooms
How we solve it: Substations and switchgear roomsThe threat Corrosive gases and humidity in enclosed electrical rooms degrade contacts and relays and cause unexplained trips.
How we protect it Air IQ atmospheric corrosion monitoring to ISA 71.04 with filtration and inhibitor recommendations.
- 05
Buried cables, grounding and export pipework
How we solve it: Buried cables, grounding and export pipeworkThe threat Earthing systems and buried steel interact with cathodic protection and cause stray-current corrosion.
How we protect it Interference testing, DC decouplers at grounding and CP of buried steelwork.
- 06
Biomass boilers and fuel handling
How we solve it: Biomass boilers and fuel handlingThe threat Fly ash, sulphur oxides and chlorides from biomass fuels corrode boiler tubes, flue ducts and fuel storage.
How we protect it Corrosion monitoring on the boiler circuit, coatings for flue-gas service and CP of buried fuel and water lines.
