‘As-a-service’ business models today are commonplace. They represent a shift towards subscription-based technology models, transforming traditional product-based industries into service-led offerings where the consumer sits at the very heart of the commercial strategy 

Of course, subscription services aren’t new in themselves – Xerox was blazing a path as early as 1959 by leasing photocopying equipment to customers who needed the service but couldn’t afford to buy the machines outright themselves. They are attractive for a number of reasons – a ‘pay for what you use’ service from a provider which retains responsibility for maintaining the infrastructure enables customers to lower costs by moving from hefty CAPEX (on-site data centres and the like) to more streamlined OPEX only. Moreover, it offers a more agile way of working – access to the most up-to-date technology which previously would have been prohibitively expensive and rapid scalability opportunities.  

With the acceleration of cloud computing and global internet access, it’s no surprise that ‘as-a-service’ models have exploded into the mainstream. Starting initially with Software-as-a-Service (SaaS) – Salesforce claims it was the first in 1999 – new models are springing up regularly across almost every industry from broad Banking-as-a-service to the more niche Data-as-a-Service and even 3D printing-as-a-Service.


And as they spring up, they are rapidly evolving beyond the simple subscription model to more complex, innovative platforms offering a wide range of services. The foundations though remain constant: customer-centric, technology-driven and data-led. Take Mobility-as-a-Service (MaaS) for example – MaaS aims to encourage movement away from private transportation use by delivering an all-in mobility solution on a technological platform, integrating disparate elements such as payment, personalised disruption messaging and electric vehicle (EV) integration. The MaaS solution is based entirely on the individual needs of the traveller, which neatly sums up ‘as-a-service’ models: they are demand-side driven.

The origins of Energy-as-a-Service  

As we highlighted in our recent whitepaper, energy lags behind the digital transformation curve compared to industries such as banking and so unsurprisingly, the Energy-as-a-Service (EaaS) model has been slower to take root. Against a backdrop of Covid-19 upheaval and climate change however, EaaS is now emerging as a broad umbrella term for service-led business models with the innovative potential to transform the energy industry. But before we explore what EaaS currently means for the sector, let’s take a brief look at where it started

Take the traditional energy supply modelproduct-based, centralised with a largely passive consumer. Energy has generally been sold as KwH units, a commodity rather than a service and certainly with the needs of the end user firmly placed at the bottom of the hierarchy. There is little doubt that one of the earliest iterations of EaaS arose from a need within the commercial industry to simplify their energy requirements, with a focus on being more streamlined and cost-efficient with sustainability options. These organisations wanted to be able to better manage overhead energy costs against a backdrop of varying time-of-day demand, emerging sustainability goals and fluctuating costs. For example, in 2017, Citigroup described EaaS as “budget certainty for delivered electricity” at a time when they had a goal of 100% RES across their enormous and dynamic portfolio. In the same year, Ericsson and Panasonic announced an EaaS offering for telecoms that would monitor and maintain energy infrastructure for mobile operators using big data analytics and energy management software, estimated at the time to reduce the cost of energy equipment ownership by up to 20%. 

 So, at this early stage, the concept of EaaS was firmly rooted in cost-containment, a significant evolution of traditional fixed-price supply contracts, but by no means a sophisticated comprehensive demand-driven solution with any real traction outside of the commercial market.  

 Over the last two years howeveras technology has developed and the value of data has come to the fore, we’ve seen EaaS evolve through the emergence of new demand-driven subscription models which monetise flexibilityFor commercial organisations, they provide value by integrating demand-based energy supply at a predictable fixed cost with the outsourcing of operations such as maintenance contracts and minimal upfront capital expenditure. Businesses can be incentivised to adapt their energy use according to peak demand, enabling suppliers to optimise usage and pass on their own cost-savings to their customers. It is an attractive user-centric model for both customer and supplier which creates cost-saving synergies on both sides. 

Energy-as-a-Service in 2020 

Last year, Deloitte called EaaS the “end-to-end management of a customer’s energy assets and services”, visualising it as the nexus between technology (IoT, Blockchain etc) and energy, including e-mobility and the maturity of RES. 

The EaaS that we see today certainly goes far beyond the C&I-focussed early models which offered cost-efficiency and portfolio management. In fact, as it matures and moves into other sectors such as utilities and e-mobility, we can see it starting to deliver a suite of tailored smart energy services to the end-user in order to add value and create a more flexible, responsive customer-centric energy system. Much like other ‘as-a-service’ models, EaaS is underpinned by data and advanced analytics – perhaps not just a joint venture with technology, as Deloitte described, but entirely enabled by it.  

Within the residential sector, for example, we can see clear parallels with MaaS when it comes to the data-driven opportunities and connected platform approach that EaaS is now offering pioneering utilities. A stream of usage data from smart meters enables utilities to not only improve their own operational processes but also deliver innovative personalised demand-based services, such as bespoke new tariffs or digital billing, to their customers on one single platform. By moving away from charging users solely for how much energy they are using, utilities are instead focussing on HOW the customers are using that energy and providing tailored service solutions – Comfort-as-a-Service to coin the well-used phrase, a clear winner when it comes to customer satisfaction and loyalty.  

In the next blog in our Energy-as-a-Service series, we’ll be exploring the ideas around ‘next-generation’ EaaS including the opportunity for future innovation across sectors such as e-mobility. In the meantime, for more detail on Energy-as-a-Service use cases, why not download our new whitepaper
