A new project to capture, store and share power generation and use data from domestic renewable energy installations, including solar, wind and solar/geo thermal sources. We will employ low-cost off-the-shelf systems, such as the emonPi, to send data to a central data store and allow students and courses to query that data in a wide variety of ways. We will make the collected data available to students and researchers.

Our initial installation makes use of the open energy monitor products, made in North Wales. These low-cost devices are quick and easy to set up, transmit their data over your domestic Internet connection and employ open-source software. They are also expandable - both to monitor a variety of sensors, including current and temperature, and into the arena of control.

Contributed data is anonymized and the location of the source limited to a partial postcode.

Project members:

  • Chris Valentine - hardware, data collection and database
  • Roger Bradley - OU Associate Lecturer
  • Allan Third - data processing
  • John Domingue - project manager

    Roll-up solar panels are being used to help power an island off the coast of Cardiff. The Rapid Roll system allows flexible solar panels to be unrolled like a carpet from a trailer in two minutes. The pioneering technology aims to meet demands from increased tourism and environmental and logistical challenges on Flat Holm.

  • Sales of new diesel and petrol vehicles to be banned from 2040 in UK
    New diesel and petrol cars and vans will be banned in the UK from 2040 in a bid to tackle air pollution, the government is set to announce. Ministers will also unveil a £255m fund to help councils tackle emissions from diesel vehicles, as part of a £3bn package of spending on air quality. The government will later publish its clean air strategy, favouring electric cars, before a High Court deadline.
  • Electricity shake-up could save consumers 'up to £40bn
    Consumers in the UK could save billions of pounds thanks to major changes in the way electricity is made, used and stored, the government has said. New rules will make it easier for people to generate their own power with solar panels, store it in batteries and sell it to the National Grid. If they work, consumers will save £17bn to £40bn by 2050, according to the government and energy regulator Ofgem.
  • World's first floating wind farm emerges off coast of Scotland
    The world's first full-scale floating wind farm has started to take shape off the north-east coast of Scotland. The revolutionary technology will allow wind power to be harvested in waters too deep for the current conventional bottom-standing turbines. The Peterhead wind farm, known as Hywind, is a trial which will bring power to 20000 homes.
  • 'Extraordinary' month for Scottish renewable energy
    Scotland had "another extraordinary month" for renewable energy in May, according to environmental groups. Wind turbines alone provided enough electricity to supply 95% of Scottish homes.

Current grid carbon intensity

Latest generation data by source as of 12 Dec 2017, 15:50:

  • Closed-cycle gas turbine - 24368 MW
  • Oil - 0 MW
  • Coal - 9740 MW
  • Nuclear - 5854 MW
  • Wind - 4635 MW
  • Pumped storage hydro - 404 MW
  • Non-pumped storage hydro - 459 MW
  • Open-cycle gas turbine - 0 MW
  • Other - 88 MW
  • French Interconnector - 0 MW
  • Irish Interconnector - 0 MW
  • Dutch Interconnector - 797 MW
  • East-West Interconnector - 170 MW

Total generation 46515MW, giving a grid carbon intensity for domestic generation figure of 624.20 gCO2/kWh

The calculations are made as follows: for each generation figure, normalise by the total demand (ignoring negative values on interconnections since this is counted in the generation elsewhere already) and multiply by the carbon intensity of each specific generation type; then divide by 0.93 to account for generation that is lost in transmission. Note that solar PV generation is not measured centrally.
