Anaerobic Digestion a Renewable Energy Technology

Anaerobic digestion (AD) is one of a number of renewable energy technologies that have become commercially available to agriculture and industrial sectors.  A key attribute of AD is that it offers multiple environmental and economic benefits, particularly for UK dairy and livestock farms.  Alongside their potential to deliver low carbon energy, on-farm AD plants also appear to be the most promising mitigation measure for reducing greenhouse gas emissions from manures and slurries. Take a look at a Powersystems Anaerobic Digestion Plant Case Study 

 

Electric Vehicles (EV), grid technology and battery storage

The global market opportunity in electric vehicles is predicted to top over $500 billion between now and 2025. This potential for transformative change creates huge opportunities for both new and existing players in the automotive sector. Speak with Powersystems Renewable EV Infrastructure team to identify how local grid technologies, battery storage and V2G systems can come together to make this happen.

 

The Future Is Renewable Energy

There are some fantastic opportunities for industries wanting to future-proof and to drive change.  The Powersystems renewable energy team see their role to educate and share information on how this is likely to be applied practically over the next five years and beyond.

 

 

How is electricity generated from renewable energy?

There are many, many ways that people make renewable energy all over the world. Renewable energy is any energy we use that comes from renewable, natural sources. Renewable means that it’s naturally replenished, so can’t run out. Things like the sun will never run out, same with trees, because although we can cut them down to make biomass energy, we can still replant them, so it’s a renewable source.

Sunlight, water, air and heat from the earth are all renewable sources that we can use to make solar, tidal, wind and geothermal energy. Sometimes renewable energy is also called green or eco energy.

What Is Renewable Energy Technology?

What Is Renewable Energy Technology?

What is renewable energy?

It is produced using natural resources that are constantly replaced and never run out

Just as there are many natural sources of energy, there are many renewable energy technologies. Solar is one of the most well-known, wind power is one of the most widespread, and hydropower is one of the oldest. Other renewable technologies harness geothermal energy, bioenergy or ocean energy to produce heat or electricity.

Equally exciting are new enabling technologies that help to manage renewable energy so it can be produced day and night while strengthening the electricity grid. These enabling technologies include battery-storage, supply prediction and smart grid technologies.

There are many different forms

  • Most of these renewable energies depend in one way or another on sunlight
  • Wind and hydroelectric power are the direct result of differential heating of the Earth’s surface which leads to air moving about (wind) and precipitation forming as the air is lifted
  • Solar energy is the direct conversion of sunlight using panels or collectors
  • Biomass energy is stored sunlight contained in plants
  • Other renewable energies that do not depend on sunlight are geothermal energy, which is a result of radioactive decay in the crust combined with the original heat of accreting the Earth, and tidal energy, which is a conversion of gravitational energy

Powersystems remains at the forefront of the Renewable and the Power Generation Industry

With so many projects successfully constructed and exporting power to the grid, whether requiring a turnkey installation, electrical infrastructure or grid connection, Powersystems are an experienced partner in all forms of renewable energy generation project. Growing environmental awareness has heightened interest in all forms of renewable energy.

Solar Energy

Powersystems remain at the forefront Renewable Energy Industries with expertise in Solar Energy, Solar Parks, Solar Farms, Photovoltaic Electricity Generating Facilities, Solar Photovoltaic Panels and associated electrical infrastructure

Powersystems Solar Energy Project

Powersystems Solar Energy Project

Solar energy is energy generated from the sun’s heat or sunlight. Solar power is energy captured from the sun which is converted into electricity, or used to heat air, water, or other fluids.

This form of energy relies on the nuclear fusion power from the core of the Sun. This energy can be collected and converted in a few different ways.

Powersystems have connected in excess of 100MW of solar farms across the South West

Solar photovoltaic

  • This technology converts sunlight directly into electricity using photovoltaic (PV) cells. The solar PV cells are combined in panels. They can be put on rooftops, integrated into building designs and vehicles, or installed by the thousands across fields to create large-scale solar power plants.
  • Concentrating solar PV uses fields of sun-tracking mirrors called heliostats to concentrate sunlight onto highly efficient PV cells located inside a receiver at the top of a mast or tower.

Solar thermal

  • This technology converts sunlight into thermal energy (or heat), which in the past has been used mainly for space heating or to heat water (such as in a solar hot water system).
  • This heat energy can be used to drive a refrigeration cycle to provide solar-based cooling, or to make steam that can be used to generate electricity using a steam turbine. Solar thermal energy can also be used in some industrial processes that currently use gas to produce heat.
  • Concentrating solar thermal technology harvests the sun’s heat to produce efficient, large-scale power generation. It uses a field of mirrors to reflect sunlight onto a thermal receiver, which transfers the heat to a thermal energy storage system. Energy can then be released from storage as required, day and night.

Emerging solar technologies

  • Research and development continue to improve existing solar energy technologies while identifying emerging innovations such as photosynthetic-based solar energy technologies and solar enhanced fuels.
  • Innovations and developments in solar energy technology and enhanced fuels will benefit everyone by making affordable and reliable energy more accessible to more UK businesses and households.

Powersystems and your Solar / Solar Park Project

There has been a large uptake in the number of solar parks being granted planning consent in the UK. Powersystems has been involved with many of these providing grid connection schemes at 11kV & 33kV. Each scheme is designed by our team of engineers and covers the requirements of the Distribution Network Operator (DNO) substation, site wide earthing and cabling to the point of connection. The whole process is managed, from initial connection application to final energisation and adoption.

Powersystems can perform much of the onsite work as well

  • Installation of HV cabling and terminations
  • Design and Build of Intake Substation
  • Incorporation of G59 protection
  • Specification and supply of Inverter Transformers
  • Site Earthing
  • Final Test and Commissioning
  • Take a look at Powersystems Solar Park Case Study Projects

Wind Energy

Powersystems remain at the forefront Renewable Energy Industries with expertise in Wind Farms, Wind Turbines and associated electrical infrastructure

  • The movement of the atmosphere is driven by differences of temperature at the Earth’s surface due to varying temperatures of the Earth’s surface when lit by sunlight.
  • Wind energy can be used to pump water or generate electricity, but requires extensive areal coverage to produce significant amounts of energy.
  • Wind power is generated by converting the kinetic energy of the atmosphere into useable electricity with wind turbines.
    Powersystems Windfarms installed across the UK

    Powersystems Windfarm

Powersystems UK projects help connect 24% of all U.K. Land Based Wind Farm generation

  • Wind is generated by complex mechanisms involving the rotation of the Earth, the heat of the sun, the cooling effect of the oceans and polar ice caps, temperature gradients between land and sea, and the physical effects of mountains and other obstacles.
  • Wind turbines convert the force of the wind into a torque (rotational force), which is then used to propel an electric generator to create electricity.
  • Wind energy power stations (known as wind farms) commonly draw on the output of multiple wind turbines through a central connection point to the electricity grid. Across the world there are both on-shore (on land) and offshore (out to sea) wind energy projects.
    Wind Turbine installation

    Wind Turbine installation

How is wind energy used in UK?

  • The United Kingdom is one of the best locations for wind power in the world and is considered to be the best in Europe.
  • In 2017 Wind power contributed 15% of UK electricity generation and 18.5% in the final quarter of 2017.
  • Onshore wind power has the lowest levelized cost per MWh of electricity generation technologies in the United Kingdom when a carbon cost is applied to generating technologies. In 2016, the UK generated more electricity from wind power than from coal.
  • Wind power delivers a growing percentage of the electricity of the United Kingdom
  • By mid-March 2019, it consisted of 9,685 wind turbines (Powersystems has completed 25% of these projects) with a total installed capacity of over 20.7 gigawatts and 12,848 megawatts of onshore capacity and 7,895 megawatts of offshore capacity.
  • This placed the United Kingdom at this time as the world’s fourth largest producer of wind power.
  • Polling of public opinion consistently shows strong support for wind power in the UK, with nearly three quarters of the population agreeing with its use, even for people living near onshore wind turbines.

Through the Renewables Obligation, British electricity suppliers are now required by law to provide a proportion of their sales from renewable sources such as wind power or pay a penalty fee.

The supplier then receives a Renewables Obligation Certificate (ROC) for each MW·h of electricity they have purchased. Within the United Kingdom wind power is the largest source of renewable electricity and the second largest source of renewable energy after biomass.

  • Overall, wind power raises costs of electricity slightly. In 2015, it was estimated that the use of wind power in the UK had added £18 to the average yearly electricity bill. This was the additional cost to consumers of using wind to generate about 9.3% of the annual total about £2 for each 1%
  • Offshore wind power has been significantly more expensive than onshore, which raised costs. Offshore wind projects completed in 2012–14 had a levelised cost of electricity of £131/MWh compared to a wholesale price of £40–50/MWh
  • In 2017 the Financial Times reported that new offshore wind costs had fallen by nearly a third over four years, to an average of £97/MWh, meeting the government’s £100/MWh target four years early.
  • Later in 2017 two offshore wind farm bids were made at a cost of £57.50/MWh for construction by 2022–23, nearly half the cost of a recent new nuclear power contract
  • In 2019 Offshore wind energy is to provide a third of all UK Electricity by 2030

Powersystems and your Wind Farm / Wind Turbine Project

Experience in the design and installation of high voltage electrical infrastructure has placed Powersystems in a position ideally suited to carryout wind farm electrical balance of plant contracts.

Hydroelectric and Electric Power

Powersystems remain at the forefront Renewable Energy Industries with expertise in Hydropower Electricity Generating Stations, Hydro Electric Schemes, Hydropower schemes, Run-Of-River Hydro Scheme, Hydroelectric Generating Station, Pumped Hydro, Storage Hydro and associated electrical infrastructure

Hydropower uses the force or energy of moving water to generate power. This power is also called ‘hydroelectricity’.

Hydro Electric Scheme

Hydro Electric Scheme

  • Hydroelectricity is electricity produced from hydropower. In 2015, hydropower generated 16.6% of the world’s total electricity and 70% of all renewable electricity and was expected to increase about 3.1% each year for the next 25 years.
  • Hydropower is produced in 150 countries, with the Asia-Pacific region generating 33 percent of global hydropower in 2013. China is the largest hydroelectricity producer, with 920 TWh of production in 2013, representing 16.9 percent of domestic electricity use.
  • The cost of hydroelectricity is relatively low, making it a competitive source of renewable electricity. The hydro station consumes no water, unlike coal or gas plants. The average cost of electricity from a hydro station larger than 10 megawatts is 3 to 5 U.S. cents per kilowatt hour.
  • With a dam and reservoir it is also a flexible source of electricity since the amount produced by the station can be varied up or down very rapidly (as little as a few seconds) to adapt to changing energy demands.
  • Once a hydroelectric complex is constructed, the project produces no direct waste, and in many cases, has a considerably lower output level of greenhouse gases than fossil fuel powered energy plants.

There are four broad hydropower typologies

  • Run-of-river hydropower: a facility that channels flowing water from a river through a canal or penstock to spin a turbine. Typically a run-of-river project will have little or no storage facility. Run-of-river provides a continuous supply of electricity (base load), with some flexibility of operation for daily fluctuations in demand through water flow that is regulated by the facility.
  • Storage hydropower: typically a large system that uses a dam to store water in a reservoir. Electricity is produced by releasing water from the reservoir through a turbine, which activates a generator. Storage hydropower provides base load as well as the ability to be shut down and started up at short notice according the demands of the system (peak load). It can offer enough storage capacity to operate independently of the hydrological inflow for many weeks or even months.
  • Pumped-storage hydropower: provides peak-load supply, harnessing water which is cycled between a lower and upper reservoir by pumps which use surplus energy from the system at times of low demand. When electricity demand is high, water is released back to the lower reservoir through turbines to produce electricity.
  • Offshore hydropower: a less established but growing group of technologies that use tidal currents or the power of waves to generate electricity from seawater

 How does Hydropower Work?

  • Hydropower is generated when falling water is channelled through water turbines. The pressure of the flowing water on turbine blades rotates a shaft and drives an electrical generator, converting the motion into electrical energy.
  • Hydropower is the most advanced and mature renewable energy technology, and provides some level of electricity generation in more than 160 countries worldwide.
  • Hydropower plants range from very small to very large individual plants and vast integrated schemes involving multiple large hydropower plants.
  • This form uses the gravitational potential of elevated water that was lifted from the oceans by sunlight. It is not strictly speaking renewable since all reservoirs eventually fill up and require very expensive excavation to become useful again. At this time, most of the available locations for hydroelectric dams are already used in the developed world.

Powersystems and your Hydroelectric / Hydropower Scheme Project

Hydropower is the oldest form of renewable energy and Powersystems have been involved in constructing the electrical infrastructure on small scale hydro schemes since the late 80’s.
Projects completed include 500kW “Run of the river” schemes and multiple turbine dam storage schemes. In both types of projects Powersystems have completed the full electrical installation package for sites including

  • Design
  • Powerhouse Fitout
  • Station Transformers
  • Main LV Switchboards
  • Power and Control Cabling
  • Turbine Control Panels
  • PLC SCADA Systems
  • Head Pond Level Sensors
  • Test and Commissioning
  • Take a look at Powersystems Hydroelectric and Hydropower Scheme Case Study Projects

Biomass and Bio Fuel

Bioenergy is derived from biomass to generate electricity and heat, or to produce liquid fuels for transport. Biomass is any organic matter of recently living plant or animal origin. It is available in many forms such as agricultural products, forestry products, municipal and other waste.

  • Traditionally, woody biomass has been used for bioenergy, however more recent technologies have expanded the potential resources to include agricultural residues, oil seeds and algae
  • These advanced bioenergy technologies allow for the sustainable development of the bioenergy industry, without competing with the traditional agricultural industry for land and resources
  • Biomassis plant or animal material used for energy production, heat production, or in various industrial processes as raw material for a range of products. It can be purposely grown energy crops (e.g. miscanthus, switchgrass), wood or forest residues, waste from food crops (wheat straw, bagasse), horticulture (yard waste), food processing (corn cobs), animal farming (manure, rich in nitrogen and phosphorus), or human waste from sewage plants
  • Burning plant-derived biomass releases CO2, but it has still been classified as a renewable energy source in the EU and UN legal frameworks because photosynthesis cycles the CO2 back into new crops. In some cases, this recycling of CO2 from plants to atmosphere and back into plants can even be CO2 negative, as a relatively large portion of the CO2 is moved to the soil during each cycle.
  • Cofiring with biomass has increased in coal power plants, because it makes it possible to release less CO2 without the cost associated with building new infrastructure. Co-firing is not without issues however, often an upgrade of the biomass is beneficiary. Upgrading to higher grade fuels can be achieved by different methods, broadly classified as thermal, chemical, or biochemical.
  • Biomass is the term for energy from plants. Energy in this form is very commonly used throughout the world. Unfortunately, the most popular is the burning of trees for cooking and warmth. This process releases copious amounts of carbon dioxide gases into the atmosphere and is a major contributor to unhealthy air in many areas. Some of the more modern forms of biomass energy are methane generation and production of alcohol for automobile fuel and fueling electric power plants.

Powersystems Generation Plant Powered by your Bio-Fuels

  • In an ever-increasing bid to fulfill the UK’s requirements for new renewable energy fuel sources, Powersystems have assisted customers in the design and construction of generation plants powered by Bio-Fuels.
  • Typically, the generation of these schemes are via reciprocating prime movers, therefore the years of experience gained in Landfill and Anaerobic Digestion (AD) Generation sectors gives Powersystems a lead when advising customers on all aspects, from site layout to electrical infrastructure, ensuring both best design practice and cost-effective solutions.
  • Take a look at Powersystems Bio-Fuels Case Study Projects

Anaerobic Digestion

Powersystems remain at the forefront Renewable Energy Industries with expertise in Anaerobic Digestion (AD) and associated electrical infrastructure

Is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels.

Anaerobic Digestion Plant

Anaerobic Digestion Plant

  • Anaerobic digestion is used as part of the process to treat biodegradable waste and sewage sludge. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill gas into the atmosphere. Anaerobic digesters can also be fed with purpose-grown energy crops.
  • Anaerobic digestion is widely used as a source of renewable. The process produces a biogas, consisting of methane, carbon dioxide, and traces of other ‘contaminant’ gases. This biogas can be used directly as fuel, in combined heat and power gas enginesor upgraded to natural gas-quality biomethane. The nutrient-rich digestate also produced can be used as fertilizer.
  • With the re-use of waste as a resource and new technological approaches that have lowered capital costs, anaerobic digestion has in recent years received increased attention among governments in a number of countries, among these the United Kingdom, Germany and Denmark
  • Although currently an infant market with approx.650 AD plants at March 2019 we see this as a sector that will grow and plan to be at the head of any expansion, as Bio-Fuel technologies develop.

Powersystems and your Anaerobic Digestion (AD) Project

  • Powersystems have connected Anaerobic Digestion (AD) generation plants powered from commercial food waste, energy crops, dairy, pig & poultry waste in the farm-based sectors.
  • We have worked alongside the major technology providers in delivering both grid connections and onsite customer works. Typically these schemes will be cable connected to the local distribution high voltage network and electrically metered onsite, from there a bespoke site distribution system is designed and installed to meet the AD Plants requirements.
  • This system would usually be comprised of a generation transformer and main Low Voltage (LV) distribution board, providing electrical circuits to the site generation and AD Plant controls.
  • Powersystems as part of the installation can specify and install the necessary Feed In Tariff (FIT) meters and auxiliary supply meters to enable generation and auxiliary loads to be appropriately allocated.
  • To date Powersytems have connected over 30 Anaerobic Digestion sites throughout the UK with many more coming online in the near future.
  • Take a look at Powersystems Anaerobic Digestion Case Study Projects

Hybrid/Enabling Technologies

  • A hybrid technology is one that integrates a renewable energy generation technology with other energy generation systems
  • Hybrid technologies can reduce the risk for investors and ensure immediate reliability and affordability. They can also support a smoother transition to more renewable energy generation in the future.

What are hybrid technologies?

  • An example of a hybrid technology would be a power plant which combines and manages electricity generation from at least two technologies.
  • For example, a plant that integrates solar energy technology with energy from gas, or another renewable source, to provide a combined energy flow that drives the plant’s power generation.

What are enabling (or related) technologies?

  • Enabling and related technologies are those which use, or more easily allow, one renewable energy source to be used with another.
  • These technologies are especially prevalent in the fields of energy storage, grid management and connection, information and communication, mapping and resource identification, forecasting and modelling.
  •  Take a look at Powersystems Hybrid/Enabling Renewable Energy Technologies Case Study Projects

Hydrogen and Fuel Cells

These are also not strictly renewable energy resources but are very abundant in availability and are very low in pollution when utilized. Hydrogen can be burned as a fuel, typically in a vehicle, with only water as the combustion product.

  • This clean burning fuel can mean a significant reduction of pollution in cities. Or the hydrogen can be used in fuel cells, which are similar to batteries, to power an electric motor. In either case significant production of hydrogen requires abundant power.
  • Due to the need for energy to produce the initial hydrogen gas, the result is the relocation of pollution from the cities to the power plants. There are several promising methods to produce hydrogen, such as solar power, that may alter this picture drastically.

Geothermal power

  • Geothermal energy is stored as heat in the earth
  • The heat is generated by the natural decay over millions of years of radiogenic elements including uranium, thorium and potassium.
  • Geothermal energy can be drawn from the hot water circulating among rocks below the earth’s surface, or by pumping cold water into the hot rocks and returning the heated water to the surface. This can drive steam turbines to produce electricity.
  • Geothermal energy holds the promise of being a renewable energy source that could operate 24 hours a day, providing baseload power for homes and industries. Geothermal energy can be used for heating and cooling purposes. There are a number of buildings, residential homes and swimming pools that currently use geothermal for these purposes.
  • Energy left over from the original accretion of the planet and augmented by heat from radioactive decay seeps out slowly everywhere, everyday. In certain areas the geothermal gradient (increase in temperature with depth) is high enough to exploit to generate electricity.
  • This possibility is limited to a few locations on Earth and many technical problems exist that limit its utility. Another form of geothermal energy is Earth energy, a result of the heat storage in the Earth’s surface.
  • Soil everywhere tends to stay at a relatively constant temperature, the yearly average, and can be used with heat pumps to heat a building in winter and cool a building in summer. This form of energy can lessen the need for other power to maintain comfortable temperatures in buildings, but cannot be used to produce electricity.

Waste-to-energy (WtE) or energy-from-waste (EfW)

Powersystems remain at the forefront Renewable Energy Industries with expertise in Waste-to-Energy Projects and associated electrical infrastructure

  • Waste-to-energy (WtE)or energy-from-waste (EfW) is the process of generating energy in the form of electricty and/or heat from the primary treatment of waste, or the processing of waste into a fuel source. WtE is a form of  energy recovery. Most WtE processes generate electricity and/or heat directly through combustion, or produce a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels.
  • With an ever-changing waste management industry, government regulations have forced the market to look at new ways of managing the UK’s waste. A result of which has been the design and construction of cleaner more efficient Energy From Waste (EFW) plants.
  • Such plants can generate electrical power via steam driven turbines or develop a ‘Syngas’ for turbine or reciprocating generation. In either form Powersystems have assisted customers in cost effective grid connections and onsite electrical infrastructure.

Ocean and Tidal

Powersystems remain at the forefront Renewable Energy Industries with expertise in Ocean and Tidal Energy Projects and associated electrical infrastructure

Ocean or marine energy technologies refer to all forms of renewable energy derived from the sea. There are two broad types of ocean energy: mechanical energy from the tides and waves, and thermal energy from the sun’s heat. Ocean / Tidal energy is classified as

  • Wave energy: This is generated by converting the energy within ocean waves (swells) into other forms of energy (currently only electricity). There are many different wave energy technologies being developed and trialled to convert wave energy into electricity
  • Tidal energy: This is generated by harnessing the movement of tides. Tides contain both potential energy, related to the vertical fluctuations in sea level, as well as kinetic energy, related to the horizontal motion of the water.
  • Ocean thermal energy: This is generated by converting the temperature difference between the ocean’s surface water and deeper water into useful energy. Ocean thermal energy conversion (OTEC) plants may be land-based as well as floating or grazing.

Powersystems and your Tidal / Ocean Project

  • The UK has one of the largest marine energy resources in the world, estimated to be more than 10GW. This along with the predictability of tidal power makes it a form of Renewable Energy that is highly attractive to grid operators as fossil fuel back-up plants are not required. To support this emerging technology, tidal projects will be eligible for five Renewable Obligation Certificates (ROCs) from the UK Government for projects installed and operational by 2017.
  • Powersystems are actively involved with the construction of the electricity infrastructure to connect marine turbines to the onshore grid. Recent project successes include the 400kW Delta Stream demonstration device in Ramsey Sound, Pembrokeshire, a demonstration device due to be in service for 12 months.
  • Take a look at Powersystems Ocean /Tidal Renewable Energy Technologies Case Study Projects

Powersystems Asks Can A Country Achieve 100%?

If you think 100% renewable energy will never happen, think again. Several countries have adopted ambitious plan to obtain their power from renewable energy. These countries are not only accelerating Renewable Energy installations but are also integrating Renewable Energy into their existing infrastructure to reach a 100% Renewable Energy mix.

Seasons Greetings from Powersystems

Christmas is here again and at Powersystems UK we look back on another successful year with customers both existing and new.

2018 brought about continued success on major UK renewable schemes, contributing to a greener national grid with the energisation of large projects such as Blackcraig and Dorenell windfarms in Scotland. Alongside works within renewables, Powersystems has worked on significant projects within the UK private industry sector, supporting prestigious and well-established UK companies. We look forward to continued successful collaboration going into 2019, with some exciting changes ahead!

To ensure continued service during the Christmas period, our head office will be open, however we will be closing at midday on Friday 21 December for festivities with our staff to celebrate another successful year re-opening on 27 December. We would like to thank our customers and suppliers for your support this year.

Wishing you all a very Merry Christmas and a prosperous and busy 2019!

Powersystems UK have now handed over Blackcraig Windfarm. Powersystems UK supported the customer by installing, commissioning and back energising the site with a Generator System to enable the Turbine supplier, Siemens Gamesa, to commission a turbine against a ‘false grid’. 

The HV Generator system comprised of a step-up transformer to energise the system at 33kV, a main and backup generator to ensure continuity of supply and to provide stability during energisation of the turbine transformers, 2MW of load banks to provide load for the turbine to generate against and LV switched inductor banks to compensate for the reactive power due to cable capacitance on the site.  All controlled with an integral  Modbus controller to automatically switch the load bank load.  

Commissioning was successful and completed in the short timeframe required. The site was then transferred to the new grid supply and was immediately online and available to generate through the meter, a pre-requisite for the customer Blue Energy in compliance with the Ofgem accreditation criteria.
