Alberta’s breeze plantation understanding scored ‘pretty conspicuous price,’ appetite researcher says
A renewable appetite understanding brokered by a Alberta supervision this week warranted “a flattering conspicuous price” for breeze power, a University of Calgary researcher says.
Three companies were picked on Wednesday after a competitive, general auction to build 4 breeze appetite plantation in a southern partial of a province.
“They got it during a cost of $37 per megawatt-hour,” economics PhD claimant Blake Shaffer told the Calgary Eyeopener on Thursday morning.
“That competence not meant many to many though this is a lowest cost we’ve seen for breeze appetite in Canada, positively — and it’s a fragment of prices we’ve seen usually a few years ago.”
Edmonton-based Capital Power, Portugal-based EDP Renewables and Enel Green Power Canada will collectively spend about $1 billion to build a farms. The new projects will be means to beget 600 megawatts of power, adequate to supply 255,000 homes. The companies will be authorised for some so-far-undisclosed subsidies from a province.
The low cost should revoke a risk renewable appetite growth has carried in a past, pronounced Shaffer, who once worked as trade executive for TransAlta.
He now works as a fellow-in-residence with a C.D. Howe Institute, where he writes about a economics of energy. On Thursday, he discussed a understanding with Calgary Eyeopener executive writer and guest horde Jennifer Keene.
Q: How does that review to jurisdictions where they have utterly a bit of purify appetite like Ontario?
A: I consider that’s one of a fears a lot of people have, to start down this trail of augmenting a volume of immature appetite we have in Alberta. Hear a lot of stories entrance out of Ontario, what it’s finished to their home appetite prices.

In Ontario, when they initial got going — rather than doing what Alberta did, that is go onward with a rival auction, get people to compete on cost — they fundamentally stranded a cost list during their window saying, “I will compensate this for wind, we will compensate this for solar.”
They were profitable in a impassioned as many as $800 per MWh for some tiny scale solar. Wind was around $100 to $150 per MWh contra this $37.
When appetite nerds like myself are removing all vehement about this price, it truly is a flattering conspicuous cost we got for breeze here yesterday.
Q: This was an auction. They were looking for contractors to bid and they went with 3 breeze companies though no solar companies. Do we know since that is?
A: The pattern of this auction was effectively to bleed a lowest cost, and right now a lowest cost is going to be breeze appetite in this province. But an critical premonition on that is, if we’re looking for a place to critique yesterday’s auction, low cost doesn’t always indispensably meant we’re removing a best value.
Solar, since it costs a small bit some-more to generate, it didn’t win this auction.
It produces appetite in a center of a day, we know, when a sun’s shining. Whereas wind’s form is a bit some-more shifted towards a night time when power’s a small reduction valuable.
In some cases, we competence cite to indeed compensate a small bit some-more to get solar’s appetite profile, that is better. But this auction doesn’t do that.
I only wrote a square that came out this morning for a C.D. Howe Institute, where I’m a fellow, where we disagree we should be celebrating this cost though in a future we need to tweak a auction pattern to commend both low cost as good as a value.
Because what we unequivocally wish is a best net advantage between value and cost, not simply low cost.
Q: We’ve listened this before that a hit on breeze appetite is that breeze doesn’t always blow. It’s only not always reliable. So will there have to be backup systems in place for all of these breeze turbines and a appetite that they intend to produce?
A: That’s positively true. The low cost doesn’t annul a fact that breeze is a non-static resource. We get a appetite when a breeze blows, not indispensably when we wish it.
I consider a aged hit on renewables was that it was both non-static and high cost. Now during slightest we’ve knocked that second partial of it away.
It’s still non-static though what we’re removing is a unequivocally inexpensive source of tender energy. So during these low prices, we can means to compensate for opposite forms of things that can concede us to confederate breeze when it blows.
What we meant by that is find a approach to store it, to figure it into a hours that we want, or simply to have backup, like we say, with other forms of supply.​
There’s many ways to do that. You could consider of carrying gas plants in backup, is one method, though that competence be a dear one in a prolonged run to have a 100 per cent form backup system.
Other methods are storage, so possibly earthy storage by pumped hydro or chemical storage with batteries, that is substantially a instruction we’re headed here in a future.
The other one is augmenting a ability to pierce appetite behind and onward between other regions, like B.C., where they have vast hydro reservoirs that can store appetite when contend Alberta’s breeze is abundant. We can boat it over there and move appetite behind in times of need
