Insights on time series data, energy analytics and the Timeseries Refinery platform.
EU coal generation fell 42% in three years. But the aggregate number hides two completely different stories — and one of them is barely visible in western European policy discussions.
France recorded more negative-price hours in Q1 2026 alone than during the entire COVID lockdown year. Spain logged 490 hours below 1 €/MWh — up from 129 in Q1 2025. We look at what the data actually shows across France, Germany and Spain.
I ran two live experiments connecting an AI agent to our data platform. In both sessions, the AI surprised me — not because of the model, but because of what the data layer gave it to work with.
Summer 2026 gas is more expensive than winter 2026 gas. That's not a typo. The seasonal spread has inverted — and Europe must fill storage anyway, or face a crisis in December.
"Marc, I feel like I'm running two companies at once. One that sells groceries. And one that runs an energy utility." This is what the energy manager of a large retail chain told me last week. He's right — and he's not alone.

The case for investing in battery storage seems obvious. Until you start building the business case. Revenue comes from stacking multiple markets simultaneously — and a small wrong assumption can move your IRR from attractive to marginal.

A renewable developer asked me: should I invest in a data platform now, or wait? On paper, waiting seems cheaper. In practice, the blind spots it creates cost far more than the platform itself.
Your team has the data. But it's scattered across systems, inconsistent, and nobody has time to clean it. Sound familiar? Here's why this is costing you more than you think.
