A Developer’s Map of the European Power Grid

#learning #programming #europe

A year ago, if you had asked me how the European power grid worked, I would have confidently answered with things that turned out to be mostly wrong.

I thought electricity simply flowed from power plants to consumers.

I thought the grid was mostly cables, transformers, and substations.

I thought software was just another supporting tool somewhere in the background.

Then I joined the energy industry.

And I discovered that I had stepped into one of the most fascinating software ecosystems I have ever seen.

The deeper I went, the stranger it became.

Electricity doesn’t behave the way I imagined. The grid isn’t a giant pipeline. Keeping millions of homes synchronized across an entire continent requires markets, regulations, forecasting, optimization, balancing algorithms, communication protocols, distributed control systems, and an astonishing amount of software quietly working behind the scenes.

It felt less like learning another technology and more like discovering another continent.

The frustrating part was that almost everything I found was written either for electrical engineers or for energy specialists who already understood the vocabulary.

As a software engineer, I wasn’t looking for equations or protection settings.

I wanted a map.

I wanted to understand who the different players were, why they existed, what problems they solved, and where software fit into the whole picture.

I couldn’t find that map.

So I decided to draw one myself.

Over the last several months, I’ve been rebuilding the European power system from first principles, one topic at a time, trying to explain it the way I wish someone had explained it to me when I started.

The result is A Developer’s Map of the European Power Grid.

It isn’t a textbook, and it isn’t a complete guide to power engineering.

It’s a collection of mental models for software engineers who suddenly find themselves working in energy and wondering how all these generators, substations, TSOs, markets, protocols, and regulations fit together.

So far, the series includes:

Part 1: Electricity Is Not Water
Part 2: The Grid Is Not a Pipeline
Part 3: How Europe’s Power System Is Organised
Part 4: Where Software Lives in the Power Grid

Each article builds one piece of the picture. By the end, my hope is that you’ll have the same mental map that took me months to build.

If you’re already working in the industry, I’d genuinely appreciate your feedback. Every article has changed my own understanding, and I’m sure there are still blind spots.

And if you’re just entering the energy world, I hope this series saves you some of the confusion I went through.
