Big change: Tesla is changing the traditional grid
Big change: Tesla is changing the traditional grid
Ten years from now, the switch on the light switch is likely to change little, as our parents or grandparents do, CNET reported. But behind the scenes, the system that sends electrons to light the lights may be quite different. Most of the electricity we use today comes from power stations, which in the future come from nearby solar panels, and then spend a few hours in the huge batteries in your garage until you are used. This is because the grid is facing the biggest change since it was first established more than 100 years ago. This time, all of us will share control with power generation companies and distribution companies. The general public, start-ups and veteran generation companies are part of the change. But this trend is one of the biggest beneficiaries of the dreamer, the Tesla electric car company CEO Elon Mask (ElonMusk). He is selling solar powered solar roofs to you, large batteries that can store all the electricity, and electric cars that can use solar cells to recharge them. Compared to other companies, musk has been in the market in a leading position. But he is helping to build a new power grid, where everyone can generate electricity, and everyone is a consumer. Homes and even power companies install large batteries that can absorb the electricity and release it when the power supply is tight. The California electric power company is responsible for leading PacificGas&Electric grid innovation efforts executives Vivek Narayanan (VivekNarayanan) said: "we are trying to get rid of the traditional one-way power grid, and grid evolution to the future." Most people will refuel the car before it runs out of fuel, but the work mechanism of the grid is completely different. At any given time, the electric company must ensure that the electricity supply is kept in precise balance with the electricity consumed by the people. When the TV soap opera "EastEnders" is over, UK power suppliers must respond to a surge in electricity demand as thousands of people begin to make tea. It is worth noting that the power grid system is very stable. Compared with the personal finance, many people need to keep a cash in the bank account to cope with the day-to-day financial fluctuations, but the grid operators' "crossing the river" is almost zero. And that's where the future is tough. Coal, power generation, hydro power and nuclear power often produce stable electricity supplies. Other forms of power generation, such as increasing natural gas power generation, are designed to meet the peak demand for electricity. But alternative sources of energy, mainly solar and wind power, will be effective when the sun or wind is strong. This makes it harder to match the power supply and demand, especially when people come home from work and the solar panels just stop generating electricity. Provide consulting services for customers in the industry Asset Management Co Lazard for North American energy infrastructure business director Jonathan mill (JonathanMir) said, despite the global warming trend has become increasingly evident, but the Trump administration wants to revive the coal power industry, although the slump in the price of natural gas means that coal power had come to an end. Michael Oster, chief executive of battery maker MichaelOster, also said: "it's the hottest time in decades, and today's grid must meet the greater demand for power supply," said EosEnergyStorage. If you own a storage facility, you can build a near average power grid." This can benefit power companies. Grid level battery storage systems (such as Tesla's Powerpack) are enough to meet the power needs of hundreds of users. Although these batteries are not cheap enough to power 750 homes, 4 hours of 1 megawatt Powerpack costs $1 million 800 thousand to install. But the cost is still lower compared to the upgrade of transmission lines and other equipment. PacificGas&Electric has been in Sacramento in the substation 80 kilometers north of the installation of the 20 billion battery, enough to supply 375 households in 4 hours. The power is enough to power 33 ChevroletBolt electric cars, or to support 36 thousand and 400 Apple 13 inch laptops, MacBookPro. The other two Tesla Powerpack projects on a larger scale, namely Hawaii Kauai UtilityCooperative 520 thousand installation Zhaoshi battery, charging for 870 ChevyBolt. The new 80 kilowatt hour battery installed by the Edison Co in southern California supports 1330 ChevyBolt. In addition, Tesla believes that when its "super factory" from 2018 to 2020 full load operation, the battery costs are expected to decline by 30%. Mills of Lazard said that solar power and wind power generation would be more popular as costs declined and storage methods improved. For power companies, grid level storage systems become more meaningful. But you may wish to buy Tesla Powerwall2 battery for $5500 for residential, said a single Powerwall2 can meet the ordinary two bedroom house all day long power supply, but the combined installation cost will reach $7000. But mill argues that such batteries are hard to sell and are not economically significant to most of us. Senior adviser RegulatoryAssistanceProject Jim Lazar (JimLazar) is also very optimistic about the potential of battery storage system, but only if people accept the cheaper option, such as the power company control water heater or ice air conditioning only in the non electricity will use the peak.
But energy price changes will change the equation. Today, most people who install solar panels on rooftops will pay the remaining fees to the utility grid when they subtract from their own homes. This is called net measurement". If you're using electricity as much as electricity, you don't have to pay for electricity. That's good news for individuals, but it's pretty bad for power companies. At present, more than 40 states have adopted the "net metering" scheme, which is a friction between power companies and solar power generation users. California and other states are changing net measurement rates and regulatory rules in order to better regulate electricity costs during peak periods. Cancelling or adjusting "net metering" encourages people to buy batteries and store electricity at home. The bill may be higher during peak hours, which is an increasingly popular billing strategy that could eventually make the battery more economical. Loek Gerak, head of the California advanced energy storage team in southern, said that if tariffs and regulatory rules change, residential storage will be "dramatically expanded"". Lazar said power companies will face a choice between life and death when millions of households are powering the grid. This evolution is inevitable, necessary, and ongoing. Although it's a bit confusing at the moment, tech leaders like musk are always prone to subvert the status quo. With the advent of solar roofs and electric cars, you'd better get used to it.
