OnGen Case Study

OnGen Expert™ - an multi-award winning commercial assessment tool for onsite renewables and storage.

Overview

OnGen Expert™ is an multi-award winning commercial assessment tool for onsite renewables and storage. It allows a user to identify energy cost and carbon savings and generate new revenue streams by assessing what renewable technologies could be deployed to a site.

Client:  OnGen Ltd.

Services:  MVP Build

Industry: Energy

Challenge

OnGen developed a sophisticated Excel model to perform the calculations necessary to determine which technologies work for a given location based on a customer’s financial or carbon-saving goals. In order to scale the model, and make it available for users to self-serve, OnGen engaged us to build a web application that included the same functionality as the spreadsheet and also to enhanced it with a more complex set of user inputs such as half-hourly consumption and pricing.

OnGen is necessarily complex. In order to give an accurate view of what would happen to a site if renewable technologies were deployed, it must consider thousands of variables and perform potentially many millions of calculations.

Solution

Results

OnGen Expert™ can concurrently perform many millions of calculations for a growing number of clients who can self-serve their assessments on the internet. The site scales with demand and remains responsive by offloading the calculations to services within AWS.
