juha saarinen: how batteries will transform the power grid - house battery
Comment: Solar is clearly in the minds of people, and my column on this topic has generated a lot of feedback.
First of all, did I pay too much electricity for 37 degrees Celsius and $2 per kilowatt hour. 15 daily charges?
Quick browsing through the consumer's Powerswitch website and the websites of other power retailers, I suggest I can save $470
$530 a year, give up the meridian and go somewhere else.
This is a nice save if so, but thankfully, clicking on different low users/standard power/economy --
The wotsit plan for different power retailers shows that I can pay 47-
If I am not careful, the fixed cost per day is high, 51c/kWh.
There are more complicated situations, such as paying the bill "discount" on time, one-
If you agree to be locked within a year or two, close the incentives and lower the price a little.
High pricing and complex plans for energy retailers are enough to motivate anyone to focus on solar power even without batteries.
Nevertheless, the battery is useful except when the sun does not shine.
Living in remote areas, for example, may mean more frequent power outages because trees pull down lines during storms.
Line companies and their front-line workers are mostly amazing in restoring power, but there is only so much they can do.
When the sky is dark and the wind blows up, you may see expensive losses if power is cut off for a long time, as food in the refrigerator and freezer will deteriorate.
Batteries can help reduce power outages and eliminate peak load on the grid.
Auckland's Vector has tried network batteries at Glen Inness and is deploying them on the beaches of Warkworth and Snell.
"Batteries can help meet the peak needs of these growing communities and can delay expensive and disruptive investments in the long term
"Term infrastructure assets, purchase time to confirm if they are really needed," a Vector spokesperson told me . ".
Saving on the construction of expensive permanent infrastructure is clearly attractive to the projected $5 Vector.
Complete 5 billion clicks of the remaining network.
This is the cost that will be passed on to consumers.
Vector says its network battery installation is portable and can be moved elsewhere if needed. Battery-
The supported micro-grid could be a way to manage the growing demand for electricity and improve network resilience without the rise in electricity prices.
When you put an electric car into a hybrid, the battery portability aspect becomes more interesting.
In order to provide a better range of battery life, they have been adding more batteries.
Holy Grail is 150 KW when the storage space about can reach 800 km.
We don't have it yet, but a 2-generation Nissan Leaf has a 40 KW mAh battery, and the new model launched this year is suitable for 60 KW mAh energy storage.
This is more than the Tesla PowerWall 2 with 13 vehicles.
Each capacity is 5 KW.
Insert a leaf into your house with Nissan's car (V2H)
System, you may survive a power outage that lasts several hours.
Community electric car parking lot and charging station and home battery, anyone?
Vector tested V2H since 2017 and last month and said it won the partnership
Funding from the government's low-emission car competition fund to build a real
So we should have some actual data on how the technology works.
Unfortunately only Nissan is pushing V2H while Leaf is still in the "register your interest" mode, so the car-as-a-house-
Overall, the battery concept is a bit of a tepid effort.
Cars are expensive (
40 kWh Gen 2 s starts at $45,000)
This makes it impossible for them to reach most people even if double
Consider the use as a home battery.
Whether it's per-
Housing, portable networks, or electric vehicle batteries that solve practical and affordable obstacles are still to be seen.
But it's good to have trials happening, because I said that sooner or later we will need something and put a tight eye on this week's cyclone Oma forecast.
