Suddenly it’s a problem there’s now a need for Site C.

You just can’t win.

Any bets that LNG Canada will be paying full commercial rates for electricity?!

Their cheapest power would be building their own natural gas-fired power plant on site, which is what I expect them to do.  Gives them total control over power needs 24/7

[Victoria Watcher]

a long term contract with bc hydro also gives them full control.

not as good as having their own power generated on site.  BC Hydro may offer a good contract but there are potentials for physical problems with power transmission

I doubt that they can build a plant that will generate the electricity demands they need. They require something like 40% of Site C's total capacity!

Most LNG plants globally run their own natural gas-fired power plants as a power source.   I can not find anything that indicates LNG Canada is committed to buying power from BC Hydro, I could have not found it, but to date it all reads like assumptions that Site C power is what will be used.

From the CBC article Bingo linked earlier:

 

 

 

Only about 20 per cent of LNG Canada's power needs will be supplied by the electrical grid. The rest — including the energy necessary to compress, chill and convert natural gas to its liquid form — will be supplied by the gas itself.

From the CBC article Bingo linked earlier:

Which is where I am coming from, the article has no hard facts 

[Jackerbie]

^ Which hard facts are you looking for? LNG Canada signed a deal with BC Hydro four years ago. It's well publicized and covered by the media. There aren't any hard numbers of the GWh provided, but the 20% figure is consistent from source to source.

 

Based on previous media releases, LNG producers will pay higher rates than existing industrial customers.

 

Here's a Globe and Mail article on that: https://www.theglobe...rticle21444513/

The Kemano Generating Station near Kitimat might be able to supply the LNG project with some of their surplus power.

 

The smelter at Kitimat consumes about 80-85% of the plant's electricity, and the remainder is sold to BC Hydro's Powerex

Except when this happens.

 

More than a million Fortis BC customers are being told to turn off their thermostats to help conserve the supply of natural gas following a ruptured Enbridge pipeline Tuesday night.

National Energy Board inspectors are at the scene of where an Enbridge natural gas line ruptured about 15 kilometres northeast of Prince George, which Fortis BC says feeds its system.

The utility is asking customers across the province to “avoid non-essential use of natural gas” as it expects a decrease in energy flow and a potential loss of service for up to 700,000 customers.

The actual liquefaction will primarily be powered by burning the gas. Power purchased from the grid will likely power other parts of the process. From the environmental assessment:

 

The GE LMS 100 gas turbine equipped with dry low NOX emissions (DLE) combustors will be used as the mechanical drive for the refrigerant compressors. There are two parallel identical compressor strings for each refrigerant circuit (train), and each string is driven by one gas turbine. A total of eight LMS 100 gas turbines are needed for the full built-out of four trains.

 

Air emissions from the gas turbines comprise primarily NOX and CO, with small amounts of PM2.5, SO2, and VOCs.The main source of fuel gas for gas turbines is Boil Off Gas (BOG) from the LNG storage tanks (90%),with the remainder from feed gas (10%).

Officially, Hydro says Site C is “on track” and due to be completed within the current $16 billion budget. That’s Hydrospeak for a year late and costing twice as much as the initial budget.

 

_____________________

 

Though Hydro reported in June that Site C was 75 per cent complete (and the budget 70 per cent spent), much remains to be done.

 

Hydro is not sure if it will be ready to begin filling the reservoir this fall or have to leave it to next year.

 

The first of six generating units is scheduled to begin operating two months after the October 2024 election. The last of the six is supposed to come on line at the end of 2025.

 

Given what has gone before, whichever party forms government after the next election might want to wait until Site C is fully operation before staging any celebration.

The Site C dam is set to be filled this fall but the project is still two years away from completion, according to B.C. Hydro.

 

The dam will power about 450,000 homes or 1.7 million electric vehicles per year to meet the province’s future electricity needs. It will generate 1,100 megawatts of capacity to meet customer demand by 2030.

 

It’s the third energy management project on the Peace River after the W.A.C. Bennett and Peace Canyon dams. It will generate about 35 per cent of the energy of the W.A.C. Bennett Dam with five per cent of the area.

 

The construction began in July 2015. It’s currently about 80 per cent done. The tunnel conversion to restrict the flow of water during the initial phase of the reservoir filling was completed this month.

The reservoir will be filled this fall after the completion of the approach channels, dam intake structures and spillways. It will take four months to fill the dam with water rising around 30 cm to 2.5 metres a day. The site expects all six generating units to produce clean electricity by fall 2025.

It will generate enough electricity for 450,000 homes. All new construction is electric heat. So many housing units are scheduled to be built each year? They are aiming at building 4000k units in the next five years. It is also likely we will electrify more than a million cars in the next five years. It is beginning to feel like there might be a problem.

[Victoria Watcher]

There should not be a problem. And all new construction is certainly not electric heat.

They outlawed natural gas as primary heat source in all new construction. What is the alternative?
Baseboard electric, forced air electric, or heat pump electric.

It's not mandated province-wide until 2030.  A few municipalities have advanced the date, but most have not.

 

Somebody needs to drive the cost of heat-pumps down.  They are just a fridge in reverse, they should not cost 15,000 freaking dollars.  They should cost $500 and you should put one in each large room, in a socket on the wall.  And when it breaks you take it in and exchange it for a new one.

 

It should be more or less cylindrical.  Weighing no more than 50 or 60 pounds.  It clips/notches into the pre-wired socket from the inside of the house.

^Thats more or less how it is in Japan. I’m working on a new biz that will drive down heat pump prices. Stay tuned

[Victoria Watcher]

 

^ They should be like that, about 12 or 14 inches in diameter and long enough that a significant portion sticks out to the exterior of the house and some lesser amount inside.

 

When you click it into place, it connects to the power, pre-wired in the wall socket.

 

Then of course they are all controlled by your phone app.

 

Again, if one fails, you bring it into the shop, get a new one, with some amount credited for your return of the casing (the unit will be factory refurbished).  None of this nonsense of a service tech coming to your house.  It's not 1955.

 

Multiple manufacturers can compete to make the units, they fit the same standard socket.

 

You can buy them, even rent them, with you only being charged a small base rate and then x amount for each hour they run.  On the rental ones, you get free exchange for life, as long as you are paying the rental.
