Where did all my energy go?

Loss Analysis Waterfall is a new widget that we’ve added to the Greenbyte Platform to give you a quick and easy view on the sites and devices that lead to the biggest losses in your portfolio. Jemima Woolverton, Product Manager, explains more.

What is the Loss Analysis Waterfall?

The Loss Analysis Waterfall is a new way of visualizing energy losses at your wind and solar assets. This widget gives Greenbyte Platform users a bird’s eye view of how their assets are performing, so that they can easily see which sites or devices are performing the worst, and then enables them to drill into more detail.

We’ve called it the Loss Analysis Waterfall because, at its heart, there’s a waterfall chart that shows the cumulative energy losses in users’ solar and wind assets. It’s relevant for both wind and solar customers, and the display looks the same for both.

What problem does this solve?

A lot of the asset managers and performance managers we speak to say they need to be able to quickly assess if their assets are performing as they should. This widget helps both groups. It shows users what is happening in their portfolio and then helps them move quickly to the ‘why?’

How does it assess whether assets are performing as they should?

Asset managers and performance managers want to know that the energy being produced at their assets in real life is as close as it can be to the energy that could theoretically have been produced in optimal conditions.

The Loss Analysis Waterfall shows asset managers the difference between ‘Energy Actual’ (i.e. energy that was actually produced) and ‘Energy Theoretical’ (i.e. energy that could theoretically have been produced). It then shares the reasons for this gap.

Why aren’t you comparing Energy Actual to the energy budget? Doesn’t that give the best idea of whether projects are meeting their financial targets?

Good question. We do see that many of our customers want to compare their actual energy production to the energy budget, and we intend to build a second widget to do exactly that.

However, we have focused on Energy Theoretical first because figures in the energy budgets are based on pre-calculations of what energy production is likely, but these statistics are based on assumptions and so can be inaccurate. By contrast Energy Theoretical looks at how much energy you could have technically produced at an operating asset during a given period. It gives you a far stronger idea of real-world problems, from curtailment to O&M issues.

Got it! So, what does this look like for users?

The widget consists of two main parts: the waterfall chart on the left and a list of the ‘top offenders’ on the right.

Okay, so the waterfall chart first. How does that work?

As you can see, the waterfall chart shows ‘Energy Theoretical’ at the top. Then you go down the waterfall and see how much energy production you are losing in three main areas: performance issues, curtailment and downtime. These are based on the usual signals you would see in the Greenbyte Platform.

There is also an additional category at the bottom called ‘residual’, which covers the losses and gains that cannot be clearly attributed to any of those categories.

Then, at the bottom, you get the ‘Energy Actual’ figure for what you produced. So, in one graphic, you can clearly see the difference between the figures and the types of loss that are having the most impact on your actual energy production.

If you click on the bars in the waterfall chart, you can also find out which sites in your portfolio are experiencing the biggest issues with those specific types of losses.

And what about ‘top offenders’?

This section shows users the ten sites or devices that are losing the most energy. The top site is the one losing the most energy in GWh and, if you click on that name or energy bar, it opens a new window so you can see the breakdown of those losses for that particular solar or wind project.

You can also see the top offending devices for that site, and their own unique losses. This means you can quickly click through to see where your losses are biggest and where you need to devote your attention.

Why should Greenbyte users be excited about this?

We think Greenbyte users will see a great benefit of this, and we’re really excited to be able to present a new way to visualize energy losses. We believe this will make the lives of asset managers significantly easier, as they will be able to zoom in and out of their losses at the portfolio, site and device level.

How do they get started?

The widget works best on a one-widget dashboard, so either you can select the Loss Analysis Waterfall widget and add it to an existing widget-wide dashboard in Analyze / Portfolio, or you can create a new one. You can also create reports with this widget.
