Start building the smart grid for real

Octopus Energy has released an API for its groundbreaking Agile Tariff - a green energy tariff which varies with the wholesale price every half hour.

For the first time, this tariff allows consumers to shift demand in response to realtime energy prices - a critical part of moving to a more sustainable future.

We're inviting engineers, data scientists and designers to help build the future.

Energy has some big challenges

Energy is going through a seismic shift right now and has some huge challenges to tackle.

Decarbonisation will grow electricity demand dramatically

With a need to electrify transport and heating and an insatiable appetite from consumers for ever more sophisticated consumer tech in the home, industry and business must constantly iterate to develop ever more innovative propositions.

Balancing the grid for renewables

The UK has signed up to ambitious decarbonisation targets, but renewable power puts unusual pressure on the grid - a sunny day might deliver a surge in solar generated power. To maintain stability, we must look to more innovative ways of balancing demand.

Commercialising the smart meter roll out

With government targets to have a smart meter in every home by 2021, the focus must be on unlocking their potential to drive value for both consumer and business. The commercial opportunity to link smart, IOT, business and consumer opportunities remains a critical question to answer if we are to deliver true value.

Some ideas...

  • Optimising charging for EVs
  • Switching time of use on high load appliances
  • Using pricing to optimise charge and discharge timing for home batteries
  • Making lifestyle recommendations to maximise savings
  • Analysing potential savings for DNOs in upgrade costs
  • Modelling ideal electric heating patterns
  • Modelling potential savings for the fuel-poor
  • Using machine learning to identify household energy patterns

The hackday will feature

Octopus Agile API

Our API enables developers to read both current and historical prices (and a whole host of other detail) - opening up the world of the smart grid, enabling devices to optimise time of use and to provide deep insight and analysis.

Real (anonymised) usage data

With anonymised real world half-hourly smart meter data from thousands of households and a year's worth of historical Agile prices to allow teams to identify patterns, qualify ideas, train machine learning engines and quantify potential economics.
