See, the thing is, where #3 applies, weโ€™re not going HAM. In many areas we are actively preventing change, not because change harms us, but because itโ€™s disruptive to incumbents.

I get the cost of forcing things that arenโ€™t ready, but thereโ€™s a tipping point where obstruction is more costly.

I totally get your sentiment, and was relevant 10 years ago, but in many areas the tide is shifting to new options being cheaper and less risky, eg solar and storage in China.

At some point your analogy is more about protecting the arms dealers.

Albertaโ€™s latest changes to industrial carbon pricing make MOU commitments harder to achieve - Canadian Climate Institute Seven days after signing a Memorandum of Understanding (MOU) with federal government, Alberta changes regulations that make the $130 minimum effective carbon credit price harder to achieve

Just one week after signing an MOU with the federal govt agreeing to strengthen industrial carbon pricing, Alberta has changed its regulations, making the agreement harder to achieve.

A new report diagrams how Flexible Interconnection and Bring-Your-Own-Capacity (BYOC) can connect data centers to the grid faster while avoiding shifting costs to other electricity consumers.

A new report diagrams how Flexible Interconnection and Bring-Your-Own-Capacity (BYOC) can connect data centers to the grid faster while avoiding shifting costs to other electricity consumers.

How do we connect data centers to the grid quickly and avoid driving up costs for other electricity consumers?

The solution: a 2-part combo of flexible interconnection agreements & bring-your-own-capacity (BYOC) arrangements, according to a new report out today from Camus, my ZERO Lab, and encoord.

It is how TIER works for electricity. Uniform benchmarks. Issue right now is oversupply of credits but that can be corrected.

03.12.2025 19:03 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

That the benchmarks are uniform within the electricity sector, not facility specific. And that credits are recoupled with the headline price, trading at something close to it. The proposed โ€œfinancial instrumentโ€ is in line with the CfDs Iโ€™ve long been advocating to do so.

03.12.2025 17:44 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

To me, saying โ€œthe price would need to get to $400 to match the CESโ€ is not the flex those saying it think it is. Itโ€™s an admission that itโ€™s a costly policy.

Better to get the bulk of reductions across *all sectors* at $170 than squeezing the last from one at $400.

Exactly. To knock out the last few GJ of gas burn youโ€™d need to regulate, or go to a much higher C price. But as you note, going after the last few GHGs at a very high cost, implied or explicit, is bad policy.

"Captain Gains" on Capitol Hill
Shang-Jin Wei & Yifan Zhou
WORKING PAPER 34524
DOI 10.3386/w34524
ISSUE DATE November 2025
Using transaction-level data on US congressional stock trades, we find that lawmakers who later ascend to leadership positions perform similarly to matched peers beforehand but outperform them by 47 percentage points annually after ascension. Leaders' superior performance arises through two mechanisms. The political influence channel is reflected in higher returns when their party controls the chamber, sales of stocks preceding regulatory actions, and purchase of stocks whose firms receiving more government contracts and favorable party support on bills. The corporate access channel is reflected in stock trades that predict subsequent corporate news and greater returns on donor-owned or home-state firms.

My favourite "let's build export capacity" pet project is:

**Retrofit Roberts Bank to export Canadian crude rather the American coal!**

Overcomes capacity limits in YVR harbour, also less risk (no bridges!). Could even justify expansion of TMX (TMXX).

Thoughts?

And, as Iโ€™ve said before to anyone who will listen, a spur line to Roberts Bank (Deltaport) to avoid Vancouver Harbour and displace US thermal coal exports!
