Interesting video here from Oxford University
Researchers at Oxford University have teamed up with energy industry partners Upside, Powervault, Mixergy and the Eden Project in a pioneering trial funded by BEIS and Innovate UK. Called the PETE Project (Power, Energy, Technology, Efficiency), it explores how smart, efficient, hot water tanks can help balance the National Grid.
Providing electricity for everyone, whenever it is needed, is a tricky balancing act. The demand for electricity must be matched by a supply, otherwise there may be a blackout. It’s also true that where the supply of electricity is greater than the demand for it, the excess must be removed from the national grid for safety reasons.
The majority of smaller sites are supplied on monthly or quarterly tariffs, these are generally referred to as non half hourly sites or NHH for short. This ranges from retail units to offices to warehouses to factory units.
Whether you have a single non half-hourly site or a portfolio of 1,000s we can help you find the best deal when your electricity contract is due for renewal.
Most NHH or non half hourly sites have been on the same tariff since the meters were installed, anything up to 20 years ago. During that time a building could have been used as an office, a workshop and warehouse – all with very different usage patterns – without the tariff being changed to reflect the change. Being on the wrong tariff could be costing you 10-15%, even with the best prices.
Suppliers will almost never recommend a change of tariff, and most brokers or consultants ignore this point too, preferring to simply offer more of the same.
At Energy Solutions, we provide our customers will the complete service.
Profile classes are used where half-hourly metering is not installed and provides the electricity supplier with an expectation as to how electricity will be consumed throughout the day.
Your profile class will give suppliers an idea of your consumption patterns and your efficiency at using the energy you consume. This in turn is reflected in the standing charge and unit rates that you will be charged. As a general rule, higher usage benefits from a higher profile.
So shops, small offices, etc are fine on an 03 / 04 tariff, whereas larger users are better off on higher numbers, 05 to 08, and the higher the number the better (lower unit costs).
If there has been a significant change is usage, it is worth reviewing your profile.

Energy Solutions has operated in the UK energy market since the late 90s – over this time we have built up an enviable portfolio of energy market data and intelligence. Previously much of this information has remained in-house and only been shared with clients. As the energy industry has developed and more facilities managers are looking at flexible or managed purchasing options, the demand for our market intelligence has grown.
As well as the pricing data showing on this site, we have also released our live Gridwatch service at Intelligence.energybrokers.co.uk. As well as showing the live generation charts that you expect from similar sites, it also gives a far more detailed breakdown of power generation over the last 4 hours, 24 hours and 7 days, as well as comparing wholesale mid-market power prices to demand and generation type. More data will be added in due course. The site is available at

The combination of circuit or fuses, electrical disconnects switches or breakers used to isolate, protect and control electrical equipment or gears from the defective condition are usually called switchgear.
Listed below are some examples of switchgear:
Let us discuss what switchgear is, how does it work, and what are its types.
The switchgear systems are connected to the electric supply system.
It’s placed in both the low and high voltage of the power transformer. It’s used for de-energising the equipment for maintenance and testing to eradicate the defect. Each time ant defect or failure (for example, short circuit) takes place on the power system, a heavy current run through the electric equipment, enormous damage to the apparatus and disruption of supply to the user.
In the course of standard operation, switchgear allows the switch to on or off distributors, transmission lines, generators and some other electric powered equipment.
The automated protective switchgear primarily includes the circuit breaker and relay.
The relay comes into action when a fault occurs, and it usually closes the trip circuit which automatically disconnects the faulty line. After that, the operative and healthy section runs the normal and required supply load. And therefore, there’s no damage to apparatus and no disruption of supply.
While the occurrence of any fault or defect in the power system, all electric apparatuses are vulnerable to have a heavy current which means the apparatus could get damaged and the supply also gets disrupted.
The power system controls voltage over 36KV, which is known as high voltage.
As the voltage is usually high, the arcing generated during transitioning operation is also high.
Therefore, additional care is taken during manufacturing of high voltage switchgear. A high voltage circuit breaker is actually the major part of HV switchgear, that’s why high voltage circuit breaker needs to have specific features for reliable and safe operations.
In most cases switchgear which is rated up to 1 KV is usually called low voltage switchgear.
The term LV Switchgear consists of low voltage switches, earth leakage circuit breaker, HRC fuses, offload electrical isolators, moulded case circuit breakers (MCCB) and miniature circuit breakers (MCB).
From three KV to thirty-six KV switchgear systems are sorted as MV switchgear or medium voltage switchgear.
Most of these switchgears are of several types. They are usually metal enclosed outdoor type, metal enclosed indoor type, indoor or outdoor type without the metal enclosure, and so forth.
The interruption channel of this particular switchgear is a vacuum, SF and oil. The primary responsibility of the MV power system is to disrupt heavy current during defective situation no matter what type of CB is being used in the medium voltage switchgear system.
Whether you need to upgrade your existing switchgear, or you require new switchgear installed, Energy Solutions can help.
