electricity shake-up could save consumers 'up to £40bn' - storage battery

The British government says British consumers can save billions of pounds due to major changes in the way electricity is produced, used and stored.
The new rules will make it easier for people to generate electricity with solar panels, store it in batteries and sell it to the state grid.
According to government and energy regulator Ofgem, consumers will save 17bn to 40bn by 2050 if they succeed.
These rules will take effect next year.
For those who allow the Internet to turn on the washing machine, they will reduce the cost in order to maximize the use of cheap solar energy on a sunny afternoon.
They will even support those who agree to close the freezer for a few minutes to meet their needs during peak hours.
They will also benefit a business that allows it to air --
Air conditioning will be turned off briefly to help balance the peak energy demand of the State Grid.
First of all, those who benefit from the rule changes will be solar panels and battery storage.
At the moment, when they import electricity to their homes or export it back to the grid, they are charged a tariff.
The government has realized that this rule has to be changed because it prevents people from using power more flexibly in a way that benefits everyone.
Thanks to improvements in digital technology, battery storage and renewable energy, these flexible innovations have generated and stored electricity in the UK for millions of people.
The new rules are designed to make a difference in this regard.
The government will set up the battery Research Institute to fund companies seeking major breakthroughs in battery research and development.
Its critics say the pace of supporting the fast-growing battery industry is slow --
South Korea, Japan and China are leading in this field.
The tiny energy savings of millions of people and companies will be integrated by traders who will provide a lot of energy savings to the State Grid when computers click.
So the energy manager will be able to trade in Negawatts instead of predicting peak demand and then build power stations to meet demand

Business Minister Greg Clark gave a further overview of the 246 investment in UK industrial strategy at the heart of Birmingham's speech.
He gave a detailed introduction to a battery technology innovation competition, which he said would help the UK to become a world leader in battery design and manufacturing.
Nicola Shaw, executive director of the State Grid, previously told BBC News that home and business adjustment of demand during peak hours may ease fluctuations in the grid from 30% to 50%.
"We are at a moment of real change in the energy industry," she said . ".
"From a historical point of view, we have created energy in large power generation organizations to power houses and their businesses.
Now we are producing energy in these places.
Mainly solar energy.
"An Ofgem source told BBC News that the current rules of energy trading are not suitable for the digital age because they often prevent people from using energy flexibly.
These rules were established before the digital revolution and before the variable renewable energy boom.
People in the industry talked about the earthquake that swept them.
At a recent UK conference, energy managers were asked which of them could foresee the development of the industry within a decade;
Only six people raised their hands.
Some will press for a degree of caution in enthusiasm: the more the energy industry embraces the digital age, the more vulnerable it is to hacking.
There have been recent reports that Russian hackers may have tried to disrupt the system.
Ofgem said the new rules will take measures to combat interference.
