The ESB are expected to introduce a new ‘time of use’ tariff scheme within the next two years. Householders will be encouraged to use power at non-peak times to ease pressure on the national electricity grid.
The utility said “It will be part of a smart metering programme and residential customers can expect to see it in 2018 or 2019.” The idea is to encourage people to use less energy and greener energy and flex demand so as to be easiest on the system.
It is not known whether the move will mean more expensive power at certain times of the day – it may simply mean cheaper energy during the night. Company trials have found that when people knew there were cheaper tariff periods, they saved 4pc to 5pc on their bills.
It was also announced that ESB would finally begin requiring payment for eCar charging points around the country. Earlier this year, the utility postponed seeking €17 per month for usage of the almost 1,000 charging points nationwide. The utility are now communicating with eCar customers about the imminent introduction of charges and are currently looking at appropriate tariffs.
The utility said “Ultimately, everything has to be paid for. We need to reinvest and keep the system up to date. We will have to charge

Ardtornish Estate is a Highland estate in Scotland located in Morvern, Lochaber. The present owner of the estate is passionate about conservation; and with the estate team has spent the last few years creating a hydro-power systems high in the hills to provide low-carbon, renewable energy.
With conservation and sustainability at the heart of the estate’s objectives, three hydro power schemes are currently in place, another is under construction, and a fifth , an Archimedean Screw hydropower turbine is due to be commissioned in July 2016. A biomass woodchip boiler heats the mansion house, and green initiatives are being developed to reduce further the estate’s carbon footprint.
The delivery of the Archimedean Screw hydropower turbine required delivery along some single track roads through stunning mountain scenery. This installation will provide a unique visitor attraction as well as supplying power to the estate businesses and holiday cottages.
Rated at 100kW this semi compact Archimedes Screw hydropower turbine at Ardtronish Estate will save 86 tonnes of CO2 annually. Mann Power Consulting Ltd., the UK based Archimedean Screw specialists designed the equipment for this project. After various consultations it was decided that the most suitable turbine for the site was a semi compact Archimedes Screw Hydro turbine which was manufactured by Landustrie based in Holland.
The Archimedes Screw hydropower turbine is a new application of an ancient technology. For thousands of years the screw was used to pump water up from rivers or streams to irrigate farm land. Now, using the same system in reverse the Archimedean Screw is being used to harness the power of the water to generate hydroelectricity. Once your turbine has been commissioned and connected to the grid you’ll be generating hydro-electric power 24 hours a day, seven days a week. Whether the power is for your own property, to sell back to the grid or a combination of both, the Archimedean Screw will likely pay for itself several times over in the course of its operational lifetime (depending on the feed-in tariffs available) . And what’s more these turbines can be scaled to suit all needs – from small domestic applications to huge industrial installations.
The basic requirements required for an Archimedes Screw hydro turbine are:
A water source with a drop of at least 1.5 metres
Access rights to that water source
A grid hook-up point less than 500 metres from the water source – unless the Screw is being used for ‘off grid’ generation only.
If your site satisfies these criteria then there’s every chance you will be able to harness the power of the waterway to generate hydroelectricity. And Eco Evolution will be delighted to pilot your scheme all the way through to delivery.
If you’re still not sure whether your site is right for an Archimedean Screw turbine, get in touch and we will be happy to discuss the specifications and requirements in greater depth.

Ludford Mill hydropower scheme is a community investment project which will supply hydropower for local households with excess power supplied to the grid. The Ludlow Hydro Co-operative made the decision to harness the river Teme for Ludlow by bringing the 17th Century listed Ludford Mill back to life by installing a state-of-the art Archimedean Screw hydropower turbine, cunningly designed to fit in with the current buildings. Installed at a 17th Century listed mill and horseshoe weir on the Teme the semi compact Archimedean Screw hydropower turbine with a maximun power output of 29kW and an estimated annual output of 170,000kWh will save 73 tonnes of CO2 annually.

The Archimedean Screw is contained inside an enclosure which is built to complement the structure of the existing buildings, and the screw itself will not be visible. The enclosure will also provide sound insulation so that noise levels will be kept very low.
The scheme was designed by Mannpower Consulting Ltd and the civil engineering work began on the hydro turbine in the second week in August 2015 and the schedule was that by the second week in October the main enclosure walls would be complete, with stop logs top and bottom, which would allow the removal of the temporary cofferdam and retreat out of the river itself.
Over the next few months between October and January preparations were put in place to build the pump house for the electrical control gear, sluice gates, screens and walkways were installed and electrical cables and hydraulic lines were in place for the arrival of the turbine.
Then 30kW Archimedean Screw hydropower turbine designed by Landustrie arrived on site in March and was commissioned by Mannpower and Eco Evolution in April.
Once again we see the Ancient power of Archimedes being used for hydropower generation because if it’s fish-friendly credentials. The Archimedean Screw turbine provides a fish-friendly alternative to conventional turbines, ideally suited to low-head (1m-10m) sites, and sites with fish protection issues. Extensive fish passage tests have conclusively demonstrated that the large water chambers and slow rotation of the Archimedean Screw allow fish of all sizes, and debris, safe passage through the turbine. As a result, the Environment Agency has agreed that no screening is required.
Global Wind Day 2016 is being celebrated through the month of June here in Ireland. Irish wind farm events are running in partnership with events taking place, across Europe and around the globe. Global Wind Day is coordinated by Wind Europe and the Global Wind Energy Council (GWEC) to raise awareness of the positive benefits of our clean, safe and renewable wind energy.
This year in Ireland we’re celebrating through the month of June with wind farms across Ireland hosting an array of events to celebrate wind energy with family open day visits and tours, 5k and 10k runs on wind farms, educational events, business events and more. The activity dates vary and some are hosting public wind farm open-days so that families can learn about wind energy and see the turbines in operation themselves, whilst others are inviting schools for fun, games and facts on wind.
It is also a day for discovery of the work that has already begun by pioneers around the world. In more than 75 countries around the world, wind farms are in operation, generating energy from a clean and renewable source.
Some events need pre-registration and booking so please check out the listing below.
Come and help celebrate Irish renewable wind energy around Global Wind Day 2016, find the nearest event to you at the listing below, and keep checking in as new events are added:

How it all began:
The Wind Day was first held in 2007, as the European Wind Day organised by the European Wind Energy Association (EWEA). The main idea was to connect a network of partners as well as using centralised communication tools, press releases and distribution of gadgets and coordinate of event organised by national wind energy associations and companies active in the wind energy field. The Wind Day in 2007 reached 18 countries, with a participation of around 35,000 people. By 2008, the event’s reach extended to 20 European countries and attracted 100,000 people.
In 2009, EWEA joined forces with the Global Wind Energy Council (GWEC) and extended the reach from European associations and companies to coordinate Wind Day events across the globe. That year, the 300 events in 35 countries across the globe reached up to 1,000,000 people.
In 2010 and 2011 between 220 and 230 events took place in around 30 countries. Since 2009, Global Wind Day has reached more than 1,000,000 people plus the thousands of people engaging and supporting the event through online means such as social media.
Last year was a great success in Ireland with over 1000 people visiting wind farms across the country. This year sees a number of wind farms across Ireland hosting an array of events to celebrate wind energy. The activity dates vary and some are hosting family days whilst others are inviting schools for fun, games and facts on wind.
The Hydro scheme is located in Donside Village in Tillydrone, on the banks of the River Don. The Village is a relatively new, sustainable community based on the site of an old papermill. The hydro scheme will use the existing mill lade with the addition of a 100kW Archimedes screw. Donside Community Hydro plan to raise the money to build the scheme via a community share offer. Aberdeen Community Energy says Donside Hydro will generate £30,000 every year for community initiatives.

The proposed Donside hydropower scheme
Aberdeen Community Energy (Ace), a community benefit society set up by members of the Donside Community Association (DCA), will be launching a community share offer over the next few weeks to back the Donside Hydropower scheme.
The proposed hydropoweer scheme will draw water from the River Don to create renewable electricity that will be sold to the national grid. Surplus profits from the initiative will be channelled into a community fund that will be used to achieve social and environmental benefits for local, deprived communities. Ace together with their partners at the DCA have been working towards launching the scheme for the past three years and are finally in a position where they can share the project with the world, and open it up to investment.
The Donside Hydropower scheme will help Scotland on its journey towards 100% renewable electricity by 2020, and it will also create a sustainable community that truly works for its inhabitants and riverside setting. Aberdeen Community Energy are already working closely with members of the Donside and Tillydrone areas to identify priorities for the community fund, with their immediate focus being on improving the riverside for public use. They are also looking at the longer term outcomes, and have set up a social enterprise called Sinergy that will route surplus income into projects that will deliver sustainable benefits for the wider area.
With construction planned for late May 2016, Ace said potential investors in the scheme could expect an “ethical, low-risk investment opportunity” delivering around a 5% return on their investment. Ace, which has so far raised around £150,000 from loans, grants and investment from Ace directors, is also seeking conversations with businesses or individuals who may be interested in supporting the initiative financially in the short term, as either a lender or investor.
The community share offer will be available for investment from April 2016. A launch event will take place at an Aberdeen city centre location in the weeks after the share offer is live.
