How can I know the hourly electricity consumption of my home or company?

How can I know the hourly electricity consumption of my home or company?

One of the fundamental aspects when deciding whether or not it makes sense to switch to self-consumption is to know your consumption profile.

Broadly speaking, the more your way of consuming is similar to the solar generation hours (that is, daytime consumptions from Monday to Sunday regularly distributed throughout the year), the more you can take advantage of your installation.

Once you’ve determined that your profile could fit the hours when a photovoltaic plant generates power, you need to tune the numbers. To do this, you need to know your hourly consumption (or hourly load curve) during a sufficiently representative time interval (unless you have strongly seasonal consumption, with three months it should be valid).

Your hourly consumption can be obtained in a much easier way than you might think a priori. To begin with, we have to differentiate between your distributor, which is the company that owns the network and equipment that brings you electricity, and your marketer, who is in charge of getting the energy you need in the electricity market, supplying it to you. and bill you for the service.

Distributors, given the nature of their business, are a physical monopoly so there can only be one in your area. Apart from putting the infrastructure to supply you with energy, it is also in charge of reading your meter. In addition, they are obliged to provide you with the data they read from your meter on a web portal. It is to this portal that you have to access in order to obtain the load curve.

In total there are 349 distributors in Spain , but the big five are distributed geographically as you can see in the following map:

If, despite the map, you cannot identify your distributor, based on the number of CUPS that you can find on any electricity bill, you can find out which distributor you belong to. For example, if the CUPS starts with ES0021, you are in the Iberdrola zone, if it is ES0031, Endesa. Here are the most typical ones:

  • 0021 – I-DE Redes Eléctricas Inteligentes SAU (Iberdrola)
  • 0031 – Edistribución REDES DIGITALES SL (Endesa)
  • 0022 – UFD Distribución Eléctrica SA (Fenosa)
  • 0027 – Viesgo Distribución Eléctica SL
  • 0026 – Hidrocantábrico Electric Distribution

Access portals of the five main distributors

Once you have identified your distributor, you should go to their website through which you can complete the registration process in your customer portal:

The registration process in these portals is completely independent of the account that you currently have in the portal of your marketer, whether or not it is the same company.

Data required to complete the registration

Depending on the distributor you have, the registration process will be more or less simple. Next, we detail the information you need to register in each of the five portals.

Once the data has been entered, you must activate your account using the code that you will receive on your mobile and choose a password to access the portal.

Get the load curve

After registering on the portal, we are going to show you how you can obtain your load curve based on four of the portals to which we have had access: Iberdrola Distribución, Unión Fenosa Distribución, Viesgo and E-Redes EDP Distribución. If you want to know how to obtain the load curve on the Endesa portal, this post explains it in detail.

  1. Iberdrola Distribution

Iberdrola makes it very easy to download your load curve. You simply have to click on the ‘Consumption’ menu in the left bar.

Iberdrola 1

Once inside, you select the period for which you want to download the load curve. In many cases Iberdrola has data for a whole year, but in many others you will have to manually check the oldest date from which Iberdrola has stored your data.

19

As soon as you locate the oldest date, you must download the data for the selected period in Excel or CSV format by clicking on the three points that you can see in the following image:

  1. Unión Fenosa Distribution

Once you log in to the Unión Fenosa Distribución portal, you must go to the ‘My consumption’ section

Union Fenosa 1

By clicking on ‘Hours’ and ‘Export consumption data’, you will be able to download your load curve in Excel format by clicking on ‘Export all available data’

22

  1. Viesgo

In Viesgo, the maximum period that allows you to download the portal at one time is six months. To do this, you must access the ‘My Measurements’ menu and then click on ‘Load Curve’

2. 3

  1. E-Networks EDP Distribution

In the case of E-Redes, as soon as you access the portal you will see a key that indicates ‘See consumption’. If we click here and select the period that interests us the most (E-Redes allows the download of a maximum interval of three months), we will obtain the hourly load curve.

ERedes 1

With the load curve unloaded, you are now in a position to fairly reliably analyze whether or not you are interested in incorporating a self-consumption installation. In the event that you determine that it is worth making a self-consumption installation, the hourly load curve also allows you to avoid one of the most typical errors when sizing the plant: paying more for a plant power that actually you will not need. In the next posts we will inform you about how to carry out these studies.
