More choice for electricity users?

When the UK’s gas and electricity industries were opened up to competition it must have irked energy suppliers that there was nothing they could do to differentiate their product from their competitors. “The same gas through the same pipes” is about as far from a unique selling proposition as it’s possible to get; but all that is set to change in the electricity industry thanks to innovative smart-energy startup Brain Power Limited.

Some of the mains supply waveforms available from BPL

BPL’s marketing experts have taken inspiration from currentĀ trends such as voltage optimisation, variable frequency drives, and power quality monitors to create exciting new electricity supply options that they describe as “fit for the age of smart meters and artificial intelligence”. Out is the bland sine-wave alternating current (top) that has been the staple for public electricity supply in the UK for 70 years or more: “in” is a spectrum of waveforms ranging from the inexpensive square wave to the edgier sawtooth (bottom) and, for the connoisseur, designer waveforms like ‘ogive’ (second from top) which co-ordinates beautifully with Victorian architectural features. “The great thing about these non-sinusoidal waveforms is that they are really rich in higher harmonics”, said a BPL spokesman.

There will be voltage options for every taste as well. 261 volts could appeal to musicians who will appreciate a voltage that equals the frequency of middle C. Nerds may go for 256 volts (because it is a “power” of 2). Initially available in single and three-phase supply only, BPL is rumoured to be releasing five and even thirteen-phase supplies after Brexit is complete, when customers will also be able to cast off the shackles of 50 cycles per second mains frequency.

Asked whether their catalogue will contain DC as well as AC options, BPL said that would be possible but only with batteries, which would be “charged extra”
