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

Smart Grid Reliability! …or Efficiency?

One of the main benefits of the Smart Grid is increased reliability. Investing in Smart Grid technologies that improve reliability may have a good benefit-to-cost ratio or not, it will depend on the value of the improvement and the avoided outage or interruption costs. Examples of such technologies are; automatic outage restoration systems, Wide Area Monitoring, energy storage at distribution level, geographic information maintenance systems, advanced protection systems, etc.

The cost to improve reliability follows an somewhat exponential curve, as having a 100% reliable system is close to impossible, the cost is close to infinite. This leads to an asymptotic curve towards the end. Something like this:
