Energy as a Service Provisioning Model: Power of Digitalisation

The energy transition, innovation in consumer energy technologies, and the pandemic shifted the stable energy ecosystem. For example, distributed energy resources (DERs), electric vehicles (EVs), and energy storage are becoming more prevalent, while the traditional centralized grid is becoming more distributed. This is resulting in a higher level of customer engagement in the energy sector.

Developments in technology are also resulting in new business models, such as peer-to-peer (P2P) energy trading and microgrids, and in new ways electricity is provided. This article will explore the shifts that have occurred in the energy ecosystem in recent years, particularly a new energy provisioning model called “energy-as-a-service (EaaS). You’ll learn about its benefits, the roadmap for energy providers to get there, and, most importantly, where to start your journey. Now, let’s get down to business.

What will the energy sector look like?

The industry has experienced changes that have affected every single aspect of it. Service suppliers have new roles, customers have new expectations, there are new market participants, and new business models have emerged. Thus, the energy as a service business model came out as a result of consumers’ striving to get more than electricity in their apartments. The grid is becoming smarter, making digitalisation a must for businesses that want to be future-proof.

New roles of energy suppliers

As generation from DERs like solar rooftops, customer-sited energy storage, and electric cars has expanded tremendously, utilities are extending their roles to electricity producers. Now, energy is not just a commodity, it’s a service that they provide through partners or solely with green generation. Additionally, energy suppliers do not just sell, buy, or resell energy, they connect energy producers among themselves. 

New customer expectations

Everyone will be able to both produce and consume. “I get energy from my solar rooftop, have capacities to store it, and am ready to share it with my neighbor. How can we interact here and what about invoicing?” This is how the role of customers will be changing, greenlighting the emergence of peer-to-peer (P2P) markets. Even if not everyone can afford it, people are interested in reducing bills and picking better deals. 

Another case scenario for customers is getting energy as a secondary product integrated into main products, such as “an electric car that has electricity” or “a house that is warm,” and having it bundled into customer-centric subscription contracts. The sellers of such products team up with energy suppliers for accurate charging through the mediation of billing solutions. 

As production costs decrease, the capacity to generate goes to micro levels, and services are supported by digital platforms, the changing energy environment will become significantly more complicated. In order to serve as a single point of contact for all of the customers’ energy-related demands, utility businesses will be seeking an aggregating agent that can deliver on that. 

New energy market participants 

A greater number of people, networked groups, and energy communities will be able to produce and share their own energy as a result of increasingly decentralized energy resources. Consumers will be able to actively engage in the energy markets by generating, storing, and selling power in addition to consuming it thanks to more openness, flexibility, and choice provided.

The power grid is “getting smarter”

As the grid is becoming “smarter,” there will probably be more changes in the next ten years than there have been in the previous decades. Advanced communication and digital technologies will enable the integration of conventional power generation, renewable generation, distribution points, and consumers into a highly automated system with a two-way flow of electricity and information.

These changes have introduced a new paradigm where energy is offered as a service. Let’s get to know about it closer. 

Energy as a Service: a new world of the efficient digitalised energy system

Energy as a Service: digital transformation in energy

What is Energy as a Service (EaaS)? It is a new ground-breaking business model for delivering bundled energy services, supported by technological and financial advancements. It is a delivery model for various solutions that integrate hardware, software, and services. Value is created by combining the numerous components that used to be sold separately but now make a bundled product.

 The energy-as-a-service (EaaS) model provides services for energy efficiency and demand management, makes it easier to incorporate renewable energy and other decentralized supply sources, and improves the proportion between supply and demand. To achieve this, higher-level digital technology and analytics are needed. EaaS may also operate on a much greater scale because it is possible to connect numerous sites in a packaged service offer. 

Energy as a Service Examples

Energy as a Service Examples

Energy Storage Subscription Service

In this model, a service provider installs and manages a battery storage system on the customer’s premises. The customer pays for the usage of the stored energy, which is particularly useful during periods of high demand or in the event of power disruptions.

Renewable Energy Subscription Service

This innovative service entails the installation of solar panels at a customer’s site by a specialised provider. Customers are charged based on the energy generated by these panels. The service provider retains ownership and responsibility for the solar equipment, enabling customers to enjoy the perks of sustainable energy without initial investment costs.

Subscription-Based Lighting Offers

These energy energy as a service solutions offer a comprehensive lighting service to businesses and industries through a subscription model. The service provider undertakes the installation and upkeep of the lighting infrastructure, while clients are billed a regular monthly fee for utilizing these lighting services.

Heating and Cooling Subscription Service

This model involves a service provider installing and maintaining heating and cooling systems within a property. In return, the property owner or manager provides regular payments for the continuous service and maintenance of these systems.

Energy Optimisation Subscription Service

This service model leverages advanced energy management software to scrutinise and enhance energy consumption in various premises. The service provider employs this technology to implement cost-saving measures, such as optimising energy self-consumption or adjusting energy use to coincide with periods of lower rates. Customers subscribe to this service, benefiting from reduced energy expenses.

Energy-as-a-Service and electric vehicle charging

Nowadays, EaaS providers also deliver EV charging and different types of business models. Electric vehicle charging is one of the mainstream trends in 2023, according to McKinsey. To illustrate, only in the UK, as new data reveals, September recorded the second largest number of battery electric vehicle (EV) registrations ever. The country has now surpassed the milestone of one million registered plug-in EVs, with a notable 25% of these registrations occurring in the current year.

The installation across the country is greenlighted by the government and Ofgem. They have initiated an action plan aimed at revitalising the market for smart electric vehicle charging, with the goal of making it the dominant method for extended-duration charging by the mid-2020s. 

A brilliant example of an energy-as a service model example in this area is a recent project from Kaluza. Being a part of a consortium, it launched a practical business model for “vehicle-to-everything” (V2X) charging. This innovative charging method not only enables electric vehicles to supply power back to the grid but also allows drivers to use their vehicles as a power source for their homes, offering an alternative energy solution during power outages. 

Benefits of Energy-as-a-Service

The most appealing advantage is making the offering easier to understand and purchase since it is by nature an increasingly multifaceted service. The energy as a service model is particularly tailored to customers’ specific needs. All ownership-related information, software, analytics, operations and maintenance are held “behind the curtain”. Here’s an overview of the model’s biggest benefits:

  • All-inclusive package (not per unit consumed) for customers; corporate ones benefit from predictable subscription payments
  • When an asset is in use, the client only pays for the output it produces—not for the asset itself or the components, maintenance, or servicing it needs. The service provider is interested to decrease  downtime and deliver assets that function well
  • The service provider is responsible for covering all project costs, incl. those for the construction, operations, monitoring, and maintenance of the equipment
  • Information flows 24/7 in real-time between the physical and digital world. Products can be monitored from source to customer, or while they are in use, facilitating fast reactions to internal and external changes.

Roadmap to getting to EaaS: digitalised energy services

Energy suppliers feel pressure to change their business models, build strong digital technology skills, provide cleaner and more environmentally friendly energy sources, and collaborate with a variety of partners to create and deliver compelling consumer propositions.

As long as companies succeed with digitalisation, they will have more capabilities to integrate new activities and implement new methods of buying and selling energy. Digital transformation allows an ‘intelligent’ interaction between people, assets, and locations – all enhanced by the spread of automation and artificial intelligence. 

First, digitise core capabilities

 Energy as a Service: digital transformation in power and utilities

Deloitte actually defines the digitalisation of key capabilities as the first step toward EaaS. They are usually connected to the same business process areas. In the utility sector, it is particularly the case of metering, billing, and customer service areas. 


Energy companies need to get insights into consumption data to understand customer behavior and consumption patterns. Why? In the world of competition, they will have to offer customized information-centric digital energy products. This makes access and deployment of smart metering a must. 


In the EaaS model, billing does not just come down to collect revenue for the product delivered. Since companies deliver mainly commodity services, the product differentiation and configuration is executed with a billing engine. The billing is a commercial product, meaning it should be adaptable, flexible, and quick. 

Customer service 

This entails offering a unique customer journey that improves the client experience in order to keep customers happy and subscribed to their services by offering top-notch energy products. This might also apply to energy as a service. Utilities will require a powerful customer care system with  with integrated digital experience and customer analytics to meet the business need for customer segmentation, acquisition, and retention, as well as to assess customer engagement and profitability.

MaxBill: energy and utility digitalisation at every step of the way

To better respond to challenges and benefit from new business opportunities, utilities need to be flexible while also resilient. Yet, the organization’s capacity for change is frequently limited by the state of its application portfolio which historically for utilities has been bloated, challenging to alter, produced by someone else, and tied to the strategy of the past.

Utilities, to digitise commercial business processes, would seek the help of an application vendor and a specialised service company for system integration. MaxBill billing software solution can help out significantly.  Its SaaS-based solution comes with a commercial off-the-shelf (COTS) product with established capabilities. These are billing and product management, customer management, partner management, order management, and revenue management. Based on the organization’s business strategy at a specific time, a system integrator (SI) may help with integrations, according to an individual utility company’s needs.

MaxBill supports digitalisation at any stage of the EaaS journey with our energy billing solutions. The team and energy supplier can focus on the needs and mission-critical operations in three essential areas (see metering, billing, and customer service) and digitise them. It also helps with the product and service range extension up to the very EaaS model, where the portfolio includes packaged business capabilities and legacy COTS applications with open APIs.
