Meet Minou Gimbrère – our data analyst

Minou Gimbrère has been working as a data analyst at Greener Power Solutions for a year and a half. She analyzes all data from our meters and batteries, makes estimates of savings, consumption and power in advance and produces reports for customers. In this interview she explains what she does.

We are increasingly seeing a trend towards the need for detailed information about nitrogen and CO2 reduction, especially in urban environments or Natura 2000 areas. Our data is often used by our clients for their calculations of emissions.

What does your work at Greener entail?

Our batteries and energy meters generate a lot of data. I analyze all of it and make sure that it is communicated to the customers as clearly as possible. When I started at Greener it was a lot of custom work, but now I have largely automated the process. In this way, the customer can not only view the raw data, but also print out how much diesel, running hours of a generator, CO2 and nitrogen emissions have been saved in a certain period.

What data do customers most need?

We are increasingly seeing a trend towards the need for detailed information about nitrogen and CO2 reduction, especially in urban environments or Natura 2000 areas. Our data is often used by our clients for their calculations of emissions.

The need for details differs per customer. Sometimes a customer needs detailed data and wants to see, for example, exactly all peak power per day and the savings per power zone per day. Other customers just want to see how much energy has been consumed in total on a project and want to be able to quickly see the total savings. We have prepared the reports in such a way that both are easy to see.

How do you determine the savings?

Our calciulations are based on the diesel generator that will be used alternatively. We receive this information from the customer, or we make an estimate of the correct genset ourselves. We have built a model to estimate as precisely as possible how much diesel, runinng hours, CO2 and nitrogen will be used and emitted in the alternative case. We have tested this model a number of times in practice and it has an error margin of about 5%.

Our batteries show very accurately what they consume and how much power has been drawn for this from the grid, from a generator, or from the sun or wind. We contrast this with the alternative situation we have modeled. In this way our savings are always quite accurate.

Which project are you most excited about?

The most fun are the projects where the use of our batteries and software means that no genset is needed at all. Often we can use a small mains connection in the area and boost it with a battery in between. That is great, because it saves 100% of emissions compared to an alternative with diesel.

But I also get very happy with projects with really high powers, where very high peaks are needed. For example, we did an HDD drilling for Van Vulpen, where the battery really works well. We saved 72% of the diesel there and those are really good figures to see.
