Quintel Intelligence

Our Expertises

We have a strategy consulting background and considerable expertise on energy systems and modeling,. We use this to develop our product, the Energy Transition Model.

Development in Ruby and more

Our calculation engine is entirely written in the Ruby programming language. This language is a dynamic, reflective, object-oriented language with a very active open source community. For the ETM it offers a very readable way to create, maintain and expand our modules.

Custom made our own tools

Where possible we use off-the-shelve products, such as compass, sass, less or bootstrap, and, if necessary we build our own tools, such as:

  • In order to retrieve information from our Graph, we have created our own Graph Query Language or 'GQL': this offers us and third parties a highly flexible way to request information from an energy system.
  • We use a custom written RSpec environment to mimic the behavior of our users. With this tool we can pull sliders, change settings and test our model automatically.

Frameworks Ruby on Rails, Backbone

Our front-end interfaces are built in Ruby on Rails, CoffeeScript, or Backbone.js. Quintel is always looking for the best open source projects to work with and contribute to.

Version control system Git

Everybody at Quintel uses our Git repositories, which we use to store our applications (we have around 10 under maintenance, from very big to extremely small). We also maintain research data in git repositories, so that we can work with branches, do git greps, and such.

Test Driven Development

Having a product that is under development for years already and for years to come, it is imperative that we have a code base that is properly tested.

Energy Modeling

Our modeling team has extensive experience in reducing the inherent complexity and interdependencies of national energy systems to their essence.

With a solid background in exact sciences (such as computer science, chemistry and physics), our modelers distill real-life technologies and processes into functional building blocks for the ETM.

Collective modeling

We have worked with several knowledge institutes, such as CIEP, KEMA, ECN, EcoFys and others.

Modeling frameworks

We have worked with a few tools for optimal modeling, but currently we use the Energy Transition Engine we have developed in house.

Energy Research

In order to realistically represent the energy system plenty of knowledge needs to be gathered on how it works. We at Quintel pride ourselves on having built an extensive body of knowledge and data on the energy system. Whenever our partners request improvements or extensions of the Energy Transition Model, we gather the required knowledge from scientific literature, our partners, experts and statistical agencies. As such, Quintel and its partners use the Energy Transition Model to pool their energy know-how in an accessible way.

Research example

An example of the kind of research performed at Quintel is found in the Masters thesis of Ir. Chris Laumans. For his internship Chris researched flexibility options for technologies that may be potentially 'disruptive' for the electricity grid. He also added network calculation functionality to the ETM. His thesis is available for download.

Energy Education

Quintel has also developed a range of educational material for the Dutch education system. Students from primary school to PhD level use these educational materials to interactively learn to understand the energy system better. More information can be found on Quintel's education page. (in Dutch).
