Centrica: Making it simpler and more efficient for customers to contribute to a clean-energy future

Explore Centrica’s journey with SAP

As a multinational British energy services and solutions provider, Centrica plc is helping foster a greener future by making it possible for customers to sell microgenerated energy from their homes and business back to the national grid. To do this, it built the custom, cloud-based Microgen solution on SAP Business Technology Platform (SAP BTP).

The Challenge

Promoting clean energy with a state-of-the-art cloud solution

Sustainable energy production is critical to the health and well-being of people and the planet.


With that in mind, Great Britain’s Smart Export Guarantee (SEG) initiative aims to promote interest in renewable electricity generation by requiring electricity suppliers to enable small-scale generation of low-carbon electricity, which can then be exported to the national grid. In return, the supplier pays the customer for the exported electricity.


To that end, Centrica plc looks to make microgeneration as simple as possible for its retail and business customers.


But the application it was using to manage the process was out of date. Not only did the system need to be taken offline to perform regular maintenances, but it was also hard to find people with relevant skills for implementing changes. This stretched timelines for applying regulatory changes and put the business at risk of noncompliance. It also made deploying new capabilities, such as bank transfer payments, UX improvements, single sign-on, and address searching, costlier and more time-consuming – making it hard to justify the costs of implementing anything but mandatory requirements.


The application also struggled to manage increasing loads, making it clear that it would not be able to sustain the more than 200 new microgeneration customers Centrica is adding every month.


To effectively manage customer, contract, and billing data for microgeneration accounts, Centrica needed to build a modern, cutting-edge, and scalable solution in the cloud.

With Microgen now running on SAP BTP, we have the scalability and flexibility to continue innovating and adding new customers. That means a lot more clean energy, which is good news for us and the planet.

The Solution

Increasing flexibility, scalability, power, and performance

To achieve the flexibility and scalability it needed for the cloud-based Microgen tool, Centrica chose SAP BTP, which provides the necessary platform services to build a comprehensive cloud-native solution.


SAP Cloud Application Programming Model was the model used to build Node.js back-end applications, and SAP Business Application Studio was used by developers to build all the Microgen applications, leveraging SAPUI5 technology and following standard guidelines for the SAP Fiori user experience (UX). Data was replicated from an Oracle database to the SAP HANA Cloud database using SAP HANA smart data integration. SAP HANA Cloud provides fast data access and data processing procedures for data-intensive operations, such as billing simulations.


One point of access for all applications was built using the SAP Launchpad service, with SAPUI5 and the SAP Fiori UX. The applications can also consume third-party APIs for things like address validation and meter reads using SAP API Management technology.


A smooth yet secure login experience is made possible with single sign-on using the Identity Authentication service and role-based access controls.


Finally, the SAP Data Intelligence solution pulls reporting data from SAP HANA Cloud to be put in files for sharing. It also retrieves billing data from SAP HANA Cloud and pushes it to Centrica’s SAP for Utilities solutions for back-end transactions, such as payment processing and correspondence.


As a partner on the project, the team from Cognizant helped make sure the Microgen application was delivered both on time and within budget.

The Result

Improving efficiency and customer service for clean-energy generators

With Microgen, Centrica has a scalable, flexible solution that serves more than 120,000 customers – with 200 more being added each month.


Not only can customers now get paid through bank transfer, but with more validations implemented and error-prone side processes eliminated, Centrica is also recording a 48% decrease in complaints. Plus, with automated appointment booking and an average drop of 13 seconds in customer handling time – a significant call centre KPI improvement – service representatives can spend time on more value-adding tasks.


Business users love the streamlined login and having all the apps they need in one place. And IT is happy with the increased agility and speed with which they can make changes and deploy new functionality. In fact, by moving to the cloud, Centrica is unlocking roughly £130,000 in cost savings and repurposing roughly £27,000 in hardware each year. And the 78% decrease in operational downtime is good news for everyone. On top of all that, regulatory changes can be implemented more quickly, thus reducing the risk of noncompliance.


The result: a more effective system for providing excellent customer service to microgenerators to promote the generation of more than 730 GWh of clean energy every year – corresponding to more than the city of Oxford’s annual electricity consumption.1
