AEG Power Solutions, a global provider of power electronic systems and solutions for industrial power supplies and renewable energy applications, today announced it has developed a unique Hybrid Energy Storage System which combines standard battery storage with power-to-heat technology to reduce the total cost of energy storage operation.
The solution can be installed in any type of facility which uses thermal processes, including local heat networks in combination with an electrical distribution network.
With the Hybrid Energy Storage solution from AEG PS, the power conversion system (PCS) becomes the central key element operating the power management and controls both the battery as well as the heating system. The PCS and all equipment required for grid connection (e.g. transformer and switch gear) therefore are used for both the batteries and the heater. The platform allows for all typical applications of standard battery energy storage in particular, frequency regulation; bby combining both systems, the capacity of the thermal storage adds up to the battery storage capacity.
“Technically, in a stand-alone battery energy storage system, explains Andreas Becker, Product Manager at AEG Power Solutions, it’s necessary to keep a battery charge stable at the 50% level in order to provide grid frequency regulation. By combining it with a power to heat system, we allow extra energy to go to the thermal process. The battery can then operate at 100% capacity.”
This in fact leads to dividing the battery total capacity required by almost two. Taking into account that they represent usually around 70% of an energy storage installation, the economic benefit of the innovation is obvious and the payback period of the investment is approximately 3 years faster in a primary control power market.
AEG Power Solutions engineers the complete solution and provides the key components such as the power conversion hardware and the power management software.
AEG PS is an innovator in energy storage and management thanks to its many decades of experience in the world of UPS, power electronics, batteries as well as international grid connection compliance. This unique combination of know-how has been leveraged to design products and solutions for energy storage.
Factories Act 1961 – Memorandum on the Electricity Regulations
Today I was having a look at some old books I had and I found a copy of the Factories Act 1961 – Memorandum on the Electricity Regulations produced by the Health and Safety Executive. Makes an interesting read, some old ways of working in this one !
The Amazing Folding UK Plug
We found this amazing plug when looking on line this week. The history behind it is from The Royal College of Art’s graduate show, and the show-stopper was this plug. Min-Kyu Choi impressed every passer by with his neat, apparently market-ready plug that folds down to the width of an Apple MacBook Air. “The MacBook Air is the world’s thinnest laptop ever. However, here in the UK, we still use the world’s biggest three-pin plug,” says Choi.
As with many things it started with a problem; the size of the UK plug versus the products that they serve. Min-Kyu Choi had a direct encounter with this having discovered a scratch on his laptop being caused by the UK plug in his bag. The UK plug, having been designed in 1947 when portability was not a consideration, had long since become outdated.
Min-Kyu set about solving the problem. Min-Kyu Choi and Matthew Judkins came together in 2009 to make Min-Kyu’s solution a reality. Having subsequently won a number of awards and having seen a concept video receive over 500,000 hits, their first product was launched in 2012 under the crowd sourced name ‘Mu’.

BS7671 Amendment 3
BS7671 – The Third amendment to BS 7671:2008, The IET Wiring Regulations, became effective on this date. Following this, contractors have a six month transition period to get up to speed with the changes and can design, install and certify to either the new or previous standard.
If you want to find out more information about BS7671 Amendment 3 then take a look at the following factsheet we found online, it gives you all the details :-
And here is the official page on NICEIC website in regards to amendment 3 :-
A new electrical training centre has opened in East Anglia with the backing of a £100,000 charitable effort. Building services charity JTL will run its own training centre on Bowthorpe Industrial Estate after the official opening with the Lord Mayor of Norwich, councillor Judith Lubbock, on Friday March 27.
The JTL was founded in 1990 as a collaboration between the Electrical Contractors Association and the union Unite, before becoming a charity in 2000 offering advanced apprenticeships and National Vocational Qualification (NVQ) assessments in the building services sector.
About 80pc of young people with JTL go on to complete their traineeships, compared to a national average of 60pc, said the charity.
Recruitment levels at JTL have, however, also been higher than the national average, which the charity attributes to a growing interest in apprenticeship careers as university loan debts exceed £30,000 and students are becoming keener to “earn while they learn”.
