The difference between energy storage project general contractors and system integrators

What is the difference between a system integrator and a general contractor?

While the system integrator approach has a technical emphasis, it is somewhat risky for the largest projects and focuses competition at contract award time; the general contractor approach is management-driven, less risky due to the use of proven management architecture and processes, and focuses competition throughout project implementation.

What does a system integrator do?

System integrators, defined as companies involved in system assembly, design and commissioning of energy storage projects are increasingly adding software expertise to their core competency set.

Should a system integrator service a battery energy storage system?

Image: IHI Terrasun System integrators are critical to the successful delivery and commissioning of a battery energy storage system (BESS) project, but they are perhaps also best-placed to service the asset once its in operation, argues Ray Saka of IHI Terrasun.

Are energy storage inverters a challenge to existing integrators?

With significant project pipelines dwarfing the existing installed base, energy storage inverter (power conversion system – PCS) manufacturers are expanding their presence targeting solar plus storage applications and existing integrators are challenging the incumbents.

What does a battery energy storage system integrator do?

Image: RWE. The battery energy storage system (BESS) industry is changing rapidly as the market grows. At the heart of what is becoming a crowded and competitive market is the role of the system integrator: putting together the components and technologies that bring BESS projects to life.

What will the system integrator landscape look like in the future?

In the future, the system integrator landscape will further diversify, primarily driven by energy storage inverter manufacturers expanding their presence, targeting solar-plus-storage applications and existing players such as Wartsila and Powin Energy targeting strategic opportunities to drive expansion.
