comment: site c is ideal clean-energy option for b.c. - battery energy storage system

Most observers believe we need to get rid of the existing fossils. fuel-
80 per cent of our primary energy sources come from the basic economy of fossil fuels,
Carbon substitution.
Achieving this goal will almost certainly bring about a "electricity economy" in which electricity becomes the preferred energy carrier.
As automakers continue to expand products for hybrid cars and pure electric vehicles, we have seen this development
Electric cars.
However, in order to make the electricity economy truly sustainable, the main means of generating electricity must be low.
Carbon resources such as renewable energy or nuclear energy.
B. In this respect. C.
Because almost all of our power is generated by hydropower, we are already the leader.
The best and the most cost-effective
Effective projects to continue our path to cleaning
The energy future in north B is already underway. C.
This is the C hydropower station on the Peace River, built by B. C.
900 MW of new hydropower-
Power generation capacity of provincial power grid.
Some people are opposed to this development because they think hydropower is the "old" technology for large-scale construction.
They seem to think that a large number of small intermittent generators using windmills and solar panels are more efficient and eco-friendly.
In fact, the opposite is true.
Both wind and solar power are intermittent sources of power that can only be relied upon when the wind blows or the sun shines.
In order to provide reliable and predictable power, there must be a lot of powerscale and cost-
Valid backup power or large battery available-
Storage capacity.
This increases the huge cost of intermittent power supplies, or requires a lot of excess capacity, hoping that the wind will always blow somewhere.
Hydropower has great advantages, based on large
Expand the energy storage in the form of water stored in the reservoir on the dam.
With the development of point C, the small reservoir behind the dam will provide a modest complement to the entire peace River energy storage.
However, one of the real advantages of the C-site proposal is that it can rely on the large energy storage that already exists in William Ston Lake, upstream W. A. C.
The Bennett Dam, a small reservoir behind the Peace Canyon Dam.
Although not widely recognized, but in B. C.
Water and electricity systems enable utilities to make huge profits in most years.

Water and electricity, buying and selling electricity in the open market, among which B. C.
Utilities connected to Alberta and along the USS. West Coast.
Alberta's electricity is mainly generated by large thermal power plants, which are not easy to cycle up and down.
So when the demand is low, they usually have the remaining power at night and Powerex can be purchased at a very low price. B. C.
Then water and electricity reduce water and electricity
Electricity can be generated overnight, and a lot of energy is stored behind the dam.
The next day, at the peak of power
Demand time in the morning and evening, it uses this stored energy to generate more than B. C. needs.
The remaining power can be sold to California at peak prices, which is often many times the cost of overnight purchases.
It is this pure arbitrage that enables Powerex to contribute millions of dollars a year to Company B. C.
Bottom line of hydropower.
According to the National Energy Commission, in the first nine months of 2015, the province's net income from low-buy and high-sell sales in this way exceeded $0. 2 billion.
This is mainly due to huge energy.
The water storage capacity of the reservoir on BC. Hydro system.
Critics sometimes argue that the power of Site C is not yet needed in B. C.
But it really doesn't matter.
Recently, once a new power supply is established, it can be used to increase the net profit generated by B. C.
Water and electricity are then returned to the province as dividends.
Then, with the increase in domestic demand, B can use more new power capacity. C.
This will ensure that the province is low enoughcost and low-
Carbon Energy will drive a new "electricity economy" for many years to come ". Robert L.
