Every company that owns solar plants wants to generate the highest return. In order to achieve this, the system’s maintenance teams need to constantly ensure the optimal functioning of all system components, especially the panels and inverters. A solar monitoring system enables you to be informed of your PV system’s performance. The industry standard: solar site monitoring It offers information about energy consumption and generation as well as possible damage to your solar system. It’s important to monitor your solar assets in some manner. Without monitoring, it is impossible to determine if your solar panels are operating at their full capacity. While system monitoring is considered a minimum requirement, detecting and identifying panel faults in large solar systems can be a complex process. Monitoring systems help detect low-performing areas, but finding the specific panel that harms the string output requires more time and advanced testing devices. By utilizing the best of both worlds with system monitoring and aerial data inspections, asset owners can improve the performance of their systems and maintain yields over time.

Yes it is, if we take what we have learned from asset management in other industries and apply it to operational safety in battery energy storage systems. Utility-scale battery energy storage systems (BESS) are becoming a more common feature of the UK electricity network for the purpose of frequency regulation and balancing. There is also growing interest in the integration of storage systems with renewable technologies such as wind and solar. This technology has a vital role to play in the global energy mix. It provides an answer to one of the biggest challenges faced by renewable generators, the intermittent nature of supply, offering a way to capture clean energy and balance energy generation against demand. National Grid has highlighted energy storage as a key growth area and estimates that as much as 30GW installed capacity could be required by 2050. BESS projects introduce new challenges for operational personnel who may be more familiar with more well-known technologies. However, we can effectively apply the knowledge and experience gained in technologies such as wind and solar to BESS projects. While the use of batteries is nothing new, what is new is the size, complexity, and energy density of the systems, and the Lithium-ion (Li-ion) battery

A ‘smart’ system that controls the storage and release of energy from wind turbines will reduce the risk of power cuts and support the increase of wind energy use world-wide, say researchers at the University of Birmingham. The system uses the variable speed of the rotors in wind turbine systems to more closely regulate the supply of power to the grid. This means that when electricity demand is high, stored kinetic energy in the turbines can be used intelligently to keep the grid stable.  University of Birmingham Enterprise has applied for a patent to protect the system. Regulating the supply of electricity to keep pace with demand is a continual challenge. Sudden outage of  power generation, such as when a generator gets damaged, can cause a ‘frequency dip’, which can lead to power cuts. The UK’s large power stations currently manage these dips by pushing out more electricity. However, as more wind turbines are integrated into the system, it becomes more difficult to balance supply and demand and keep the system stable, as frequency dips in national power grid occur more quickly and more severely than before when wind generation became such a significant element of electricity generation.

Engineer Award winner crowned for work on world-first underwater drilling rig for offshore renewables Winners selected from a shortlist of 27 Eight up-and-coming green energy stars have been honoured throughout the first ever Young Professionals Green Energy Awards Week (June 15 – 19). The awards, which would normally take place in front of around 250 guests at a black-tie event in Glasgow, were this year taken online due to the COVID-19 pandemic. Winners include Elsa Ramírez from Leask Marine, who scooped the Engineer Award for her work in designing the world’s first submersible drilling rig of its kind and size - a £1.6 million project to support the offshore renewables sector. She joins seven others who were presented with a Young Professionals Green Energy Award via video on Twitter for their bright and innovative contributions to Scotland’s renewable energy industry. Declan Bryans was announced as the Innovator Award winner for his key work in a project between the University of Strathclyde and Mersen UK, pushing battery electrode materials “beyond their current known limits” and increasing performance efficiency from 56% to above 90%. Recognition also went to James Ferguson from the European Marine Energy Centre and Industrial Doctoral Centre for Offshore Renewable Energy (IDCORE), who received the Academic

The Ingeteam Group has provided 16 GW solar inverter power throughout the world and maintains 8 GW. Its technology is present in the world's main photovoltaic facilities. Solar is the renewable growing most in the world. The technology manufactured by the Ingeteam Group allows for the supply of the equivalent to the consumption of over 6 million people, population greater than countries like Norway, Costa Rica or Denmark, thanks to its commitment to solar photovoltaic energy and the continuous development of technological improvements oriented to this sector. The boost given by the company to the photovoltaic sector in recent years and which increases year after year, has allowed it to reach 16 GW of power installed throughout the world. Ingeteam has since 2001 been providing photovoltaic inverters for solar plants from its factory located in Navarra. In addition, it has 8.1 GW of solar power maintained, distributed in 568 solar farms in 17 countries around the world, becoming one of the main service providers for the solar sector in Spain and leader in LATAM. Its technology is present in some of the world's main photovoltaic facilities, like Sweihan PV Plant, one of the largest plants in the world, located in Abu Dhabi

Doosan Lentjes is pleased to announce that it has signed a contract to supply a fabric filter for the power station in Chvaletice, Czech Republic. It is the second contract for the supply of filters for this plant that Doosan Lentjes has received from the owner, Sev.en Energy, who will act as the main contractor for the new project. The current order includes the retrofit of boiler 2 of the 4x205 MWe power plant with a new low-pressure pulse-jet bag house filter. Doosan Lentjes’ scope of work in the project will include the engineering, the delivery of key filter internals and the fly ash transport system. Completion is expected in the second half of 2021. An extended scope including plate work for filter, bypass heating system and a complete flue gas duct system is currently under discussion and will be awarded separately. The new filter systems will remove solid particles from the flue gases and ensure full compliance with the relevant emissions legislation. The plant will thus help to reduce drastically the effects of dust emissions on human health. In addition, the retrofit measures will enable a more efficient fly ash transport, which will reduce the operation costs of the conveyors.  “The so far

These innovative new masks reduce the spread of infection, whilst ensuring FR PPE requirements are still adhered to Any workers needing to wear FR garments and a facemask, need an FR mask to avoid material melting into skin when exposed to extreme heat ProGARM, the UK’s leading Arc Flash and FR protection specialists, has developed a new flame-retardant (FR), anti-viral, reusable face mask, designed to offer some protection against both COVID-19 as well as injuries caused by fire or an Arc Flash. The new washable face mask is manufactured from three layers of fabric; meta-aramid, Viscose FR and bi-component PTFE/PU FR membrane, which helps to provide anti-viral protection to help guard an operative’s face, nose and mouth against respiratory droplets and airborne particles. The mask is also designed to help protect against the dangers of an Arc Flash or fire risk, and eliminate the risk that non-FR face masks pose, whilst also providing a potent prevention tool against the spread of infection. Mark Lant, technical expert at ProGARM, explained: “As COVID-19 lockdown restrictions are eased, increasing numbers of operatives are returning to work and must now adhere to additional health and safety measures, including the use of face masks, to
