The Power in Your Hands App

The Power in Your Hands App

The Power in Your Hands project will be providing data on the energy use of households, and St. Peter’s School, which are in the Greenlands area of Tavistock, and connected to the Meavy Way low voltage (LV) substation.

We’re developing a computer based application, which you could also access on a tablet or smart phone.

This will provide information about energy use across the substation area at different times of the day.

Going forward, energy companies will be looking at introducing tariffs with different rates at different times of the day.

We’d like to give you an opportunity to work with us to understand how this could benefit you in the future.

Here’s an example of information we’ll be providing. It’s in the form of graphs and shows usage on October 4th.

The first one shows the power used across the Meavy Way LV substation by each of the three ‘feeders’ (each substation has a number of ‘feeds’ to the different properties. Meavy Way has three feeders).

The second one shows the total power used by everyone connected to the Meavy Way substation.

The Power In Your Hands – OpenLV

The Power In Your Hands – OpenLV

The Power in Your Hands is a local community energy initiative running in the Greenlands area of Tavistock for local householders and St. Peter’s School.

  • Want to reduce your energy costs?
  • Find out more about energy use locally?
  • Where our local energy comes from?
  • How bills could reduce in the future?

If YES, get in touch … Call 0800-233-5414, email or let us know your details via our Contact Form.

The Power in Your Hands is one of seven community energy pilots running in the UK as part of a graound breaking trial that will provide access to open data on local electricity networks. This should make energy more democratic and benefit you. We’ll be working to see how.

Its part of a project called OpenLV. 

This is an exciting project all about electricity. The OpenLV project is making local electricity data openly available for the first time ever and the Greenlands area of Tavistock, together with St. Peter’s School, is one of seven neighbourhoods involved across the S.West, S.Wales and the Midlands.

Your substation is where electricity is turned from a high voltage dangerous current to the low voltage electricity you use at home. Thanks to a piece of kit called an LV-CAP™ we will be able to learn more about electricity use in the Greenlands neighbourhood and work together to change our energy use habits, maybe even saving on our bills as we go!

We’re designing a website to share the data the LV-CAP™ collects, so that local residents and St. Peter’s School can see peaks and dips in electricity demand.

Knowing about our local electricity use means we can try to avoid overloading our substation and in the future, it might even be possible to have electricity tariffs which offer cheaper energy at off-peak times of day.

This video will explain more about OpenLV.

Would you be keen to find out more about the community’s energy use?

If YES, get in touch … Call 0800-233-5414, email or let us know your details via our Contact Form.

OpenLV project selects businesses and communities for trials to access open data from local electricity networks

OpenLV project selects businesses and communities for trials to access open data from local electricity networks

Business and community competition winners have been selected as part of a ground breaking trial that will provide access to open data on local electricity networks. The winning innovation ideas could have a real impact on the future of local networks while providing benefits to a wide range of users.

The OpenLV project selected 17 applications from the business and academic arena as well as 7 successful applications, including Tamar Energy Community, from community organisations. All 24 projects will now progress to the next stage, in most cases developing apps to access data from the networks.

OpenLV, a Network Innovation Competition project led by Western Power Distribution and EA Technology, is opening up live data from local electricity networks for the first time.

Examples of community projects that have been successful in being approved for OpenLV trials include apps that will:

  • Enable home owners to use energy generation and storage in the most effective way
  • Provide a visual representation of substation demand and local generation in order to inform the development of local tariffs
  • Show energy demand across a village, to help balancing of local generation, storage and demand
  • Help optimise the match between photovoltaics (PV) and heat pump installations, so that local households flex their demand to minimise losses in the low voltage network
  • Let households know when there is high demand at the local substation, to help build the case for local business models
  • Create a public approach to reducing peak demand on substations, to lower carbon emissions, and ultimately help tackle fuel poverty
  • Raise awareness of energy usage in a tower block and demonstrate how residents can save money on bills by shifting demand from peak times.

Some examples of business and academic projects that are due to access data through OpenLV are as follows:

  • Studying the effects that localised renewables-based generation and consumption would have on local energy services
  • Investigating how future energy technology in homes could help alleviate low voltage network grid constraints and allow the roll-out of low carbon technologies without the need for costly reinforcement
  • Feeding LV network data into a prototype energy project identification platform that identifies solar energy and ground source heat pump potential as well as building performance
  • Utilising LV network data and a dedicated OpenLV platform to implement managed EV charging
  • Bringing LV network data and existing academic research into the construction of a dynamic pricing model based on current grid demand integrated with an energy trading platform
  • Developing a software application that allows electrical appliances to be automatically managed according to smart grid requirements.

Mark Dale, Innovation Project Manager at Western Power Distribution, comments: “Having greater visibility of local network power flows will give Network Operators the confidence to accept greater numbers of Low Carbon Technologies such as Electric Vehicle charge points and Distributed Generation. OpenLV, with the LV-CAP™ platform, will open up information about the capacity of local networks and create this visibility for WPD as well as for the successful participants.”

Richard Potter, EA Technology’s OpenLV Project Manager, adds: “When we opened the competition for businesses and communities to submit ideas for using open, live electricity data, we didn’t know what response to expect, so I’m delighted that we’ve had so many applications, and so many good ideas to progress to the trial stage.

“Ultimately, the technology being trialled by OpenLV is expected to be adopted in substations throughout Britain, providing useful data to a wide range of sectors including electric vehicle charging companies, renewable energy developers, property developers, facilities managers, smart city planners, operators of private energy networks, the electricity industry itself, and of course local communities.”

About OpenLV

The OpenLV Project is trialling an open software platform in electricity substations that can monitor substation performance and electricity demand. The LV-CAP™ platform is designed to integrate with third party products to enable network control and automation, and increased customer participation in network management. The platform will host applications provided by a diverse set of developers, such as community groups, businesses and universities, providing a variety of services to network operators, communities and the wider industry.

As part of the OpenLV project, the software will be installed in 80 Low Voltage (LV) distribution substations located in Western Power Distribution’s (WPD’s) licence areas – the Midlands, the South West and South Wales. The software could ultimately be deployed across the electricity network.

The project will use three approaches to demonstrate the platform’s ability to provide benefits to the network owner, customers and service providers.
