IFA2, National Grid’s fourth interconnector, can provide enough clean energy from France to power 1 million British homes, avoiding 1.2 million tonnes (Mt) of CO2 emissions. By 2024, National Grid’s portfolio of interconnectors will provide enough zero carbon energy to power 8 million homes a year, avoiding a total of 100 million tonnes (Mt) of CO2 emissions by 2030. National Grid today launches Britain’s latest interconnector, IFA2. The 149-mile-long power cable runs along the sea bed between Portsmouth, Hampshire in the UK and near Caen, Normandy in France sharing surplus clean energy between the two countries. IFA2 is expected to deliver 1.2% of Britain’s electricity needs, enough to power up to 1 million homes with zero carbon energy. By the end of it’s first year in operation, IFA2 will have helped avoid 1.2 million tonnes (Mt) of CO2 from entering the atmosphere, equivalent to planting 50 million trees. IFA2 is the latest feat of engineering helping to transform Britain’s energy system. In the last decade, Britain’s power grid has decarbonised faster than that of any other developed country with a 64% decline in carbon emissions[1]. Interconnectors have played a critical role in this: every year, National Grid’s three existing interconnectors power the equivalent of 5 million homes with zero carbon energy. This will increase to the equivalent of 8 million homes a year by 2024, as a further three interconnectors are completed, avoiding a total of 100 million tonnes (Mt) CO2 emissions by 2030. That emission reduction equates to taking 2 million cars off the road. Furthermore, as the country’s renewable energy capacity, such as offshore wind, increases, interconnectors will enable Britain to sell any excess renewable energy to neighbouring countries. Despite the pandemic, IFA2 has remained on time and on budget. The 1,000 MW high voltage direct current (HVDC) electrical interconnector is National Grid’s second link to France and is the result of a shared £700 million investment, with partners RTE. UK Energy Minister Kwasi Kwarteng visits IFA2 today as it enters its energisation phase which allows electricity power to run through the cable ready for testing before going live. With the energisation of IFA2, National Grid now has four operational interconnectors – two to France (IFA and IFA2), one to the Netherlands (BritNed) and one to Belgium (Nemo Link). Two further projects are under construction – Norway (North Sea Link, operational 2021) and Denmark (Viking Link, operational 2023). Interconnectors allow the UK to trade clean energy with neighbouring countries, exporting it during times of excess generation, and vice versa. They play a critical role in the UK’s transition to clean energy resources – connecting the UK to hydropower in Norway, wind power in Denmark, and carbon-free nuclear power in France. Jon Butterworth, CEO of National Grid Ventures, said: “While the world is focused on the pandemic and managing the knock-on effects on our lives, we know that progress towards net zero can’t afford to falter and Britain needs to keep up the momentum in reducing harmful carbon emissions. The launch of the IFA2 interconnector, linking France and Britain’s power grids, is an important step in accelerating our progress to a cleaner, greener future.” Kwasi Kwarteng, Minister for Business, Energy and Clean Growth, said: “The opening of this IFA2 interconnector will provide enough clean electricity to power one million British homes so I am delighted to see this joint venture being launched. “Recent government commitments to the development of our offshore wind infrastructure show how the UK is a world leader in low-carbon energy generation and the IFA2 will allow us to share those benefits with our friends and neighbours in France.”
Private water supplies in Scotland are more likely to fail stringent water quality tests than public supplies, warns the UK plumber approval body WaterSafe. WaterSafe is highlighting the risk to public health as figures from the Drinking Water Quality Regulator1 show more than 10 per cent of tests on privately owned and operated water networks failed to meet drinking water quality standards in the latest published results. This is an increase on 6.5 per cent last year and 125 times the rate of failures in public drinking water supplied by Scottish Water, which continues to be among the safest in the world. Local authorities are responsible for regulating private water supplies – carrying out risk assessments and monitoring them. Each year the Drinking Water Quality Regulator, which regulates public supplies, publishes a report on private supplies based on the local authorities’ findings. These findings have prompted WaterSafe and the Drinking Water Quality Regulator to urge private water supply owners and operators not to take any chances when it comes to protecting their networks – and customers – from potential contamination. About 200,000 people in Scotland receive their drinking water from private water supplies, which supply homes, as well as schools, community halls, hotels, caravan parks, B&Bs and other businesses. Water samples failed due to a number of reasons, including poor water quality at the source, insufficient treatment of the water or poor or no maintenance of the plumbing and treatment systems. Julie Spinks, Director of WaterSafe, said: “There are more than 22,453 registered private water supplies in Scotland which supply drinking water to nearly 200,000 customers across households and businesses, but this report shows a worrying proportion of the samples taken have been deemed unsafe. “Our message to those who own and operate these networks and sources of water is very clear – always be sure to employ a qualified plumber, such as WaterSafe approved as they are properly trained and competent in the water regulations which govern public water supplies. It makes sense to apply these same standards to private supplies to keep them equally healthy and avoid the risk of contamination right up to the tap.” Sue Petch, the Drinking Water Quality Regulator, said: “It is concerning that the quality of private water supplies is not improving. It is vital that these supplies are improved so that people using them have a safe and reliable supply of drinking water. “Local authorities can offer advice and support as well as enabling access to a Scottish Government grant to make improvements. “Private water supplies have many risks, and it is vital that those working on them are competent to do so. We support WaterSafe, as its register of approved plumbers is there to help those responsible for protecting public health make an informed choice and not least ensure any work is done safely by a skilled and competent plumber using approved materials.” The annual Drinking Water Quality Report for public and private water supplies can be read at https://dwqr.scot/information/annual-report/.

Why do we want wind energy from the sea Wind energy will play a major role for the world in the future. Because wind energy is a lot better for the environment than Fossil fuel. To arouse wind energy there are few things necessary. First of all you need a lot windmills but first they have to be built that takes a lot of time after that they need to be transported to sea that will also take some time. For a windmill park you need of space and other people or other facilities should not be bother by it. Another good thing for windmills on the sea is that on the sea a lot wind is, how more wind there is how more energy the windmills will make. Wind turbines how they are made? Tower: The tower is made of an steel tube with a inner ladder there in because you can climb via that ladder to top of windmill. There is a cabine with the main system in it. The tower is with pile driving and a pile drive hammer put in the ground. Rotor and rotor blades: The rotor and the rotor blades are very important for the windmills because via these things they generate energy Nacelle with drive train: The nacelle with drive train. Keep the windmill always producing wind energy because the nacelle with drive train take care that windmill will follow the wind for example the wind direction changed from north-west to south-west the drive train will ensure that windmill also change to the new wind direction. Electronic equipment: The windmill consist of a little electric system for the sensors in the windmill because than knows the windmill where the wind is coming from. With these sensors you can also measure the wind speed and the temperature of the wind. Offshore wind farm installation Creating an offshore wind farm can be a challenging job. Few parties have the necessary materials and the experience to install offshore wind farms. Several parties are involved in the installation of an offshore wind farm and they need to work together. Usually XL monopiles are used for the installation of wind farms. In some cases up to 12 meters long. The monopile is the foundation of the offshore wind farm and is a crucial component. The monopiles are placed in the sea and form the foundation of the wind farms. The entire platform rests on these piles. The complexity of the installation means that it is often a multi-year trajectory. Once the installation has been completed, it is possible to work on renewable energy sources that reduce the cost of energy consumption and use renewable energy.
As per expert projections, by 2030, the power consumption will rise 70% over today’s levels. On the other hand, energy efficiency systems will contribute to 57% of the decrease in GHG (greenhouse gas) emissions. The energy used in building facilities, all residential, commercial, and industrial facilities, is the largest creator of GHGs, and electric power makes up about 50% of emissions attributed to commercial and residential buildings. Buildings can tackle this issue by producing more energy than they consume. Recent regulations reflect this objective. For instance, the EU’s EPBD (Energy Performance of Buildings Directive) stipulates that all new buildings should achieve zero-energy by 2020. But, most building facilities are far off from meeting this objective. To achieve CO2 and energy efficiency goals, effective energy management measures starting with efficient energy consumption measurement needs to be implemented on an enormous scale. Monitoring and electrical meterings are the vital measurement tools and the building blocks for competent energy management. Efficient monitoring and electrical metering offer building operators and owners the critical data they require to enhance their building’s energy performance. In an owner-occupied, single operator office building, a quality monitoring and electrical metering solution can produce instant energy savings of about 10%. In the long term, facilities can achieve improved energy use control, and monitoring can save up to 30% in energy utilization. Continual automatic metering solutions utilize dynamic energy dashboards to display building energy consumption and operation data. Images, tables, and graphs illustrate energy information clearly, so sound decisions can be made. For instance, an energy use dashboard may indicate that the building’s ventilation system utilizes more energy than usual. This alert can make the operator decrease motor speed by a few Hz, which will lower consumption without affecting performance. Continuous automatic electrical metering also offers building occupants, operators, and owners access to the needed data to optimize existing power supply contracts and negotiate new, more cost-efficient ones. Multisite building operators and facility managers can aggregate loads to discuss bulk utility contracts. Further, users can utilize precise shadow bills to identify billing mistakes and determine if suppliers are meeting the contract terms. How to Start the Energy Management Procedure? To make sure that auditing and electrical metering plans meet regulatory and user requirements, you need to measure performance against relevant metrics. For instance, the standard metrics in office buildings are kWh/occupant and kWh/m². In hotels, kWh/overnight or kWh/occupancy rate are important metrics, while kWh/production rate is a crucial metric for industrial buildings. You should also correlate the data with cooling and heating degree days to compare the building’s existing consumption with past years and with facilities in other places. To start, organizations need to pinpoint user requirements and decide the scope of energy monitoring solutions developed for the future. Next, they should determine the performance data and metrics to be gauged to connect building activities and energy consumption. Afterward, the relevant project team needs to decide the metering places (type of electrical meter + location) that will permit operators to control and monitor the building according to their goals and ensure the collected information facilitates the desired assessment. Lastly, electrical meters should be chosen based on the energy objectives of the business. If currently used primary meters have the ability to read energy information, they can be reused for that purpose. Otherwise, new energy and electrical meters need to be installed. You should pick additional meters based on building operation goals and metering points standards. The Final Word As a recommendation, we suggest before you make any decisions regarding electrical works and procedures, you must consult a reliable provider or licensed professionals who can help determine your unique requirements and find the ideal electrical and energy solutions for your needs. Hiring an expert service your electrical systems ensures peace of mind in terms of safety, appropriate installation, and prevention of unwarranted incidents

The electricity market is evolving to allow a higher integration of variable energy sources and a new class of devices is approaching the market to satisfy this necessity. In the new report released by IDTechEx: “Potential Stationary Energy Storage Device to Monitor”, the emerging class of energy storage devices, characterized by long storage duration and MW size power output, are investigated. While existing energy storage devices are already populating the market, from Li-ion batteries to pumped-hydro energy storage, this new class of storage technologies will aim to complete the puzzle of the energy storage market. Pushed from the electrification of the automotive sector, Li-ion batteries have been deeply investigated in the last decades and are currently the standard choice for short and medium-duration storage. On the other end of the storage market, pumped hydro energy storage (PHES) are the main energy storage systems supporting the grid. These systems have a power capacity of GW scale (1000s of MW), and long storage time, from days upwards. In between these two storage systems, a new group of storage devices is now approaching the market, with an intermediate power range, between MW to GW scale and an energy storage capacity that is almost indefinite. Power and storage capacity comparison of different technologies. Source: IDTechEx Research report “Potential Stationary Energy Storage Device to Monitor” The devices investigated by IDTechEx include: Gravitational Energy Storage (GES): Piston-Based GES (PB-GES) Underground PHES (U-PHES) UnderWater GES (UW-GES) Advanced Rail Energy Storage (ARES) Compressed Air Energy Storage (CAES) Liquid Air Energy Storage (LAES) The market addressed by these systems aims to improve the quality, and resiliency of the electricity grid, and distribution networks. Therefore, it is aiming to address the Front-the-Meter (FTM) section of the electricity grid. These devices, as investigated in IDTechEx’s new report “Potential Stationary Energy Storage Device to Monitor”, support the electricity grid providing peak-shaving service, grid deferral, and frequency regulation, among other possible services. Moreover, because some of these technologies involved the use of several turbines, some of these devices can address more than one service at the time, therefore increasing the value stacking of these technologies. Although they come with high capital costs, and are in their initial demonstration phase, these devices are a promising solution to stabilize the electricity grid and reach a high level of integration of variable renewable energy sources.

In one of the first key Thames Water AMP7 announcements, Barhale has been awarded a four-year, £22M programme of inspections and works on the Thames Water Ring Main (TWRM) and Raw Water tunnels. Under the Thames Water Tunnels and Aqueducts Programme, the civil and infrastructure specialist will carry out monitoring and maintenance on a total of 35km of ring main tunnels and a further 9km of raw water tunnels. Associated works include the refurbishment of four HIVs (High Integrity Valves) and relining a 1.8km length of the 2.5m inlet and outlet tunnels for the QEII Reservoir at Walton-on-Thames. The TWRM is an 80km long, 2.5m diameter tunnel built between 1988 and 1994 to take water from five treatment works and transfer flows via pumping stations housed in shafts along the route. It is a major part of London’s water supply infrastructure and carries an average daily flow of 0.3 x109 gigalitres – a little under one-sixth of the capital’s daily demand. Phil Cull, Barhale’s Southern Region Director believes that the business has benefitted from its unrivalled experience of working on the Ring Main over many years. “Under AMP6 we worked closely with the Thames Water team to refurbish 19 of the 22 shafts,” he said. “It’s meant that we have gained insights and knowledge of working across the Ring Main that is second-to-none. We are very pleased that experience has been recognised by Thames Water and to be given the go-ahead on this important programme of works. “The TWRM and the raw water tunnels are absolutely critical pieces of infrastructure for London and the scale of the task cannot be underestimated. To put it in perspective, one element of the programme of works will be the replacement of all of the grout hole caps along 27km of tunnel – a total of 217,000 at around 8 per metre.” Mark Grimshaw, Water Production Manager for Thames Water, said: “Providing a reliable and safe supply of water to our customers is a top priority for us so it’s vital we have the right people working with us to look after the infrastructure that makes it possible. We’re glad to once again have Barhale on board to maintain and improve such key pieces of our London network.”
