Our product for infrastructure assets

Change the way you manage your clean energy portfolio so you can work safer, smarter and more efficiently

Renewable energy investment is highly competitive

As a portfolio grows, often too much time is spent compiling reliable asset info, answering endless questions and report requests. The data that is available is basic at best, and inaccurate at worst.

Sennen collects, organises and validates a wide range of data into a centralised database for you to consult, manage and share through live dashboards. Crucially, it allows you to interrogate complex data, giving much greater insight into what’s happening and maximise asset value.

See the big picture

To compete, it takes a lean operation that can maximise asset value.

Designed around you

We care deeply about creating a system that your team will love using. Sennen deployment begins with a collaborative process, designing a configuration that meets your business requirements. We will share our own industry best practices, combine this with your needs and create the schema to propel you forward.


How do we scale up?

We found the best way to embed Sennen is to start simple and give immediate value to users. Once familiarity is established you can progressively increase the amount of data and features that the system will hold.


Can it be rolled out onto existing environments?

Yes. Sennen can add value throughout the project lifecycle. Sennen can be part of the first design brief or equally brought into fully operational systems. Typically, clients will have a mixture of operating and construction phase projects and we are well versed in getting to grips with these complexities


Bespoke Development

If you have a vision for a feature that doesn’t fit with our existing module list, we can build a bespoke dashboards(s) and bring it seamlessly through into your system only.


Intellectual property

Sennen owns all the IP in its system and all our clients benefit from regular updates and new features. However, should you wish to add processes that are uniquely yours we would be pleased to agree a different approach.

Integrate the tools you already use

We designed Sennen to be both flexible and extendable. Our approach is ground up, giving you what you need to make informed decisions. Your existing system may cover some of your needs. Our preference is to work with you and integrate rather than replace something that is fit for purpose.
