Responsive network maps

Fast, responsive maps that let power modellers view, edit, and inspect assets across even the largest networks. Zoom, pan, and interact with your entire grid in an interface that keeps up with you.

Interactive data visualisation

Lightning-fast charts that fetch, resample, and display massive datasets in real time. Interactive visualisations put analysts and modellers closer to the insight.

Global weather and climate data

Explore interactive weather forecasts and historical climate averages with smooth, intuitive visualisations. Access global data for temperature, wind speeds, solar irradiance, and rainfall to inform your energy models.

Effortless scenario analysis

Create unlimited scenarios and compare results easily. No more juggling dozens of spreadsheets or losing track of assumptions. Convexity keeps scenario analysis tractable and organised, so you can focus on insights, not file management.

Bankable-grade accuracy

Accuracy you can bank on

Convexity delivers outputs you can trust for investment decisions. Models built on our platform are already being used by energy analysts in the real world.

Human-readable custom constraints

Legacy tools make custom constraints a nightmare of complex code. Our domain-specific language lets you write constraints that read like simple Excel formulas.

Battery charging window

Restrict storage charging to off-peak hours

Minimum renewable capacity

Ensure minimum renewable investment

Maintenance shutdown

Schedule planned outages for generators

Emissions cap

Enforce carbon policy in capacity expansion

minimum_renewable.dsl
-- Require at least 5,000 MW of wind + solar capacity

SUM(
    Generator.capacity
    WHERE type IN ("wind", "solar")
  )

Convexity agent mode

Agent mode.

Convexity's agent can build, edit, and run your models for you. Describe what you need in plain language — add assets, run sensitivities, generate charts, or set up entire country models from scratch. It operates directly on your model, executing tasks faster than the best modelling teams can today.

TESTIMONIALS

What our users say

Giannis Vrochidis

Energy Systems Specialist

I am really impressed with how quickly Convexity accelerated our work. We were impressed with how much quicker and smoother we could work with in-built scenario handling and visualisations.

Maurizio Gargiulo

Energy Modelling Specialist

Convexity is transforming how we develop our models. It enables us to work faster and make our modelling work more accessible to our clients.

Patrick Calnan

Energy Market Expert

One of the central pillars of our business is understanding the market and analytics. Convexity allows us to join those two elements to get deep insights. Convexity has a very slick interface and is easy to install.
