Yedlin_ plans to shift power generation away from coal to renewables unclear _ calgary herald

In late November, the Alberta government was receiving praise for its adoption of a climate strategy that included the implementation of a carbon tax and a commitment to phase out the use of coal for electricity generation.

The government promised that as much as 30 per cent of electricity would be generated from renewable sources. Gaz 67 dakar But talk to the companies that are active in that space and there remains a fair bit of confusion as to what this really means.

A letter sent recently by the Canadian Wind Energy Association and the Canadian Solar Industries Association to provincial Energy and Environment ministers clearly lays out the confusion.

At issue is whether the targets mean 30 per cent of energy consumed or 30 per cent of energy-generating capacity. Gas and water In addition, the government has yet to clarify what the “as much as 30 per cent” means. Electricity worksheets grade 6 Is it 25 per cent? 28 per cent? No one knows what the actual number will be, and until that is also defined there will be no one stepping forward to invest in renewable capacity.

The concern stems from the fact not all renewable energy sources and technology are created equal. Gas mask ark In other words, 100 megawatts of capacity will generate different amounts of electricity, depending on the technology and the power source.

As things stand today, the installed generation capacity in Alberta last year was 16,000 megawatts, capable of producing 140,000 gigawatt hours of energy, which is the maximum amount that could be generated if everything were running at 100 per cent capacity. Gas monkey monster truck body Consumption in 2015 amounted to 80,000 GWh, and of that, about 10 per cent came from renewable sources: five per cent from wind and five per cent from hydro.

The question in the letter asks whether the government wants to replace two-thirds of the coal-fired capacity, which amounts to 4,200 MW, or does it want to replace two-thirds of the actual energy generated by using coal?

When it comes to reliability, coal and natural gas-fired power are hard to beat and there is no denying the emissions from coal-fired power are problematic.

In fact, Germany’s use of coal for power is growing, as a result of its commitment to get off nuclear power, and it’s using the dirtiest coal to feed its electricity plants, lignite. Electricity lessons grade 6 The same phenomenon is being seen in Britain and Japan.

Because if you break it down into what the numbers actually mean for new power generation, it starts to resemble the adage we offer our kids when they are overwhelmed: How do you eat an elephant? one bite at a time.

First, what needs to be accepted is that wind and solar are not as reliable as coal and natural gas because on an average annual basis, wind generates power 30 per cent of the time and solar is between 15 and 20 per cent. Impact of electricity in the 1920s That compares with the coal and natural gas options which only get interrupted for maintenance or other issues, thus able to generate power more than 90 per cent of the time.

The letter makes the statement that “a renewable energy target based on electricity generating capacity provides no certainty as to how much electricity will actually be produced.”

Second, if one assumes the number works out to between 4,000 and 6,000 MW to get to the 30 per cent threshold of consumption in the next 15 years, that works out to annual construction of 300 MW to 400 MW capacity per year.

The typical cost of a wind farm in Alberta is $2.5 million per MW, which means a 100 MW farm would be $250 million; if we are looking at 300 MW, it’s $750 million, and so on.

But that assumption is tied to the forecast for electricity demand growth. Gasket t 1995 It also doesn’t — or can’t — take into account the impact of new technologies that are developed and surpass wind in terms of reliability. Electricity synonyms The wind turbine technology has changed in recent years, and can operate at lower wind speeds. Gastronomia y cia That’s significant. Electricity and magnetism worksheets 4th grade But what happens if something comes on the scene that is 50 per cent reliable? That changes everything again.

The best way to explain this is that while wind and solar are both more expensive options, consumers are not expected to feel the impact of that higher cost on their power bills. Electricity billy elliot karaoke with lyrics That’s because the way the climate panel’s recommendations were structured, the carbon tax dollars will be used to offset the higher cost of the wind or solar generation. Gas 66 That said, part of this involves the government landing on a policy that new generation will be situated in the regions where there is existing transmission; to do otherwise means to potentially strand that infrastructure, which is decidedly undesirable.

Producers are asking for the government to build and publish a transparent procurement plan so they can move ahead and make decisions that help to achieve the government’s objectives.

Confusion equates to uncertainty, which does not exactly spur investment commitments, especially when we are talking about billions of dollars for long-term projects.

Platitudes only last for so long — and they certainly don’t provide the clarity on which companies can make important, long-term investments in this province.
