Energy suppliers were long seen as faceless billing departments. A newer generation of companies has tried to change that image by treating energy as a technology business, and Octopus Energy is one of the most widely discussed examples in the UK. Looking at the areas it emphasises helps illustrate where the wider industry may be heading.
Software as the backbone
Octopus has built its own technology platform, known as Kraken, to manage customer accounts, billing and data from smart meters and devices. The company has also licensed this platform to other energy businesses. The broader idea is significant: as homes add solar panels, batteries, electric cars and heat pumps, suppliers need software that can coordinate millions of devices and respond to changing conditions on the grid.
Tariffs that follow the grid
Traditional tariffs charge similar rates regardless of when electricity is used. Smart, time-of-use tariffs instead reflect how wholesale prices and grid demand shift across the day. When renewable output is high or demand is low, prices can fall, encouraging customers to run appliances or charge vehicles at those times. Shifting demand like this can help balance a grid that relies more heavily on variable wind and solar power. Whether such a tariff saves money depends entirely on a household's habits and flexibility, so it is worth comparing options carefully.
Investing in renewable generation
Through its associated investment activities, the wider Octopus group has backed wind and solar projects in the UK and abroad. Owning or funding generation links the supply business more directly to clean power and gives the company a stake in expanding renewable capacity.
Electrifying homes
Heating and transport account for a large share of household emissions. Octopus has promoted products and services around both, including heat pump installation and electric vehicle tariffs and charging offers. The thinking is that cleaner electricity only cuts emissions if homes use it in place of gas boilers and petrol engines.
Looking at newer technologies
Beyond today's mainstream options, the industry is exploring several emerging approaches:
- Local and community energy, where nearby generation supplies homes and businesses in the same area.
- Battery and storage solutions that store surplus renewable power for later use.
- Green hydrogen, produced by splitting water with renewable electricity, which may suit sectors that are hard to electrify directly.
- Vehicle-to-grid arrangements, where parked electric cars feed power back when the network needs it.
Many of these remain at pilot or early commercial stages, and their eventual role is still uncertain.
A sector-wide effort
No single company can decarbonise an energy system. Progress depends on network operators, regulators, manufacturers, installers and households working in the same direction. Octopus's approach shows how a supplier can position itself as a technology and service company in that transition. Consumers considering any provider should compare tariffs, service quality and contract terms on their own merits, rather than on brand reputation alone.
