Job description

The power system operates blind. Not anymore.

Ably delivers high-fidelity, true real-time power market and grid analytics for power trading, generation, and grid operations - built on synchrophasor sensors.

The Problem

Power Systems Are Flying Blind

The power system is mission-critical and governed by real-time physics - yet operated with delayed visibility and control . Even as a trillion-euro infrastructure, the grid still lacks a true, high-resolution, real-time data layer at the distribution level.

Traders and operators are making critical decisions without the data they need . Power underpins everything - yet the grid operates without true real-time visibility.

A New Real-Time Data Layer

Ably Intelligence is a data-as-a-service platform delivering high-fidelity, true real-time power market and grid analytics for power trading, generation, and grid operations. The platform is powered by proprietary synchrophasor hardware and continuous data output from a distributed measurement network.

Our plug-and-play sensors capture high-resolution waveform data at over 100,000 samples per second , time-stamped and with nanosecond precision - creating a sensing network that makes the invisible physics of the grid visible - in real time.

Why It Matters

We deliver real-time physical flow data at a granularity and latency unavailable anywhere else. By observing grid physics, we surface signals before they materialize as congestion, imbalances and new price formations.

Balancing Market Participants

Distinguish local stress from systemic events - enabling more precise bidding and reduce costly allocations in the balancing mechanism.

Local vs. systemic

Interconnector Outages

Ably taps production data from selected signaling plants in Southern Norway to infer hydro producers' water values in near real time . By tracking weekly re-optimisation by major reservoir players, we detect small, systematic dispatch shifts that signal updated SDDP runs.

Ably enables real-time detection and precise localization of ground faults - reducing risk, cutting costs, and improving grid stability.

High-resolution, time-synchronized data gives operators a true picture of grid conditions, enabling earlier fault detection than traditional systems.

Precise Localization

Pinpoint the exact location of ground faults on the network - reducing response time and minimizing damage.

Predictive Maintenance

Shift from reactive to predictive maintenance - scheduling interventions before failures occur and reducing operational costs.

Where Grid Data Becomes Grid Intelligence

Each sensor added to the network expands a proprietary sensing layer capturing real-time physical grid data. As the network scales, correlations across nodes compound in value and insight.

This powers advanced ML and AI models grounded in real grid physics and training data- not simulations. The result is groundbreaking intelligence that understands the grid as it actually behaves.

Executive Team

Built by Power Systems & Market Experts

Co-Founder & CPO

Experience from Point Carbon and building trading analytics for equity and power markets. New builds & M&A of hydro assets in the Nordics. Combines deep quantitative market knowledge with product thinking, turning complex energy data into valuable tools.

Serial entrepreneur and investor with multiple international successes, including Point Carbon and Spond. More than 20 years experience building energy analytics platforms.

Join Us

We are building the data backbone of the energy transition

We are a small, focused team at the intersection of power systems physics, advanced measurement technology, and energy markets. If you want to work on problems that genuinely matter - and have real-world impact on how the grid is operated and traded - we want to hear from you.

Responsible for testing and debugging mixed-signal electronics, IoT hardware, and developing test systems for our proprietary PMU devices. You will work across prototype validation, production readiness, and fault analysis - ensuring devices are reliable and ready for field deployment.

Open Role

Embedded Firmware Engineer

Develop and maintain low-level firmware for our PMU hardware - real-time data acquisition, high-precision time synchronisation (GPS/PPS), and reliable field communication over cellular and fibre. You will work close to the metal on systems where timing accuracy is measured in nanoseconds.
