Upcycling sun-tennas

The following picture was taken in Casablanca from the Kenzi Tower one month ago. It isn’t the best example, though, for example, in Cairo, it strikes more to the eye.

What do you see?…

Antenas techo

Actually, there are approximately 200 TV antennas on the roof-tops. Let’s zoom in a bit:

Antennas 25 In this portion, corresponding to one building alone, you have around 25 units.

With the advent of cable television, wireless video streaming and other technology, these antennas could soon become stranded assets in many countries. Imagine how many could be left useless and need recycling. While thinking about asset utilization and the sharing economy, I couldn’t help but think:

What can they be used for instead?… Sigue leyendo

Capacity first?

…then Reliability, then Efficiency?

Developing an electrical network is a question of priorities. As is developing anything I guess… Which priorities do you think are most important?

You probably agree that the first step in building an electrical system is bringing access to electricity to most of the population, right?

Capacity to efficiency

This might seem solved, but in reality, access to electricity is still far from being universal. Still 1,2 billion people don’t have access to electricity. It’s in fact part of sustainable development goal 7, and, actually, the road to SDG7 is the road to Energythaca.

While building additional lines and power generation units to solve access to electricity, the values of reliability and efficiency are normally not on the top of mind for system planning. What if access to electricity is provided by renewable microgrids, would values like reliability and energy efficiency be achieved at the same time? Sigue leyendo

Asset utilization Vs Energy transition

Collaborative economy, also called the sharing economy, is growing, and it can be understood as a synonym for resource efficiency and increased asset utilization. It also allows the energy transition. How? An example; car sharing, offers increased asset utilization of the vehicles and fosters the energy transition with more sustainable mobility.

In the energy sector, and in the case of utilities, this is not very common, but let’s try to look at some trends;

For example, grid interconnections, as proposed with the EU Energy Union policy, is part of a more collaborative economy. It means the sharing of power capacity and available renewable resources in an extended market. Of course it is not peer-to-peer, but instead “grid-to-grid”. Interconnections improve asset utilization (of the most competitive assets at least, as well as avoiding investments in peaking capacity) and also help toward the energy transition as abundant renewable power can be exchanged between countries.

For Spain, with high generation overcapacity, to increase interconnections is key to making use of existing power capacity and avoiding wind spilling, for example.

However, there is another example of improved asset utilization where there is a conflict with the energy transition…
