Audrey Zibelman’s work is done


The Global relevance of New York State’s clean-power targets.

Amusing that Audrey Zibelman announced her impending move to Google just as I decided to write a piece about the New York plan to go Green where she honed her skills in network planning and administration. Read and weep for our beloved country.

In the past year, several US states have announced 100 percent clean-power targets—meaning complete reliance on low-carbon sources such as wind and solar—to be achieved over the next 20 to 30 years. The European Union hopes to go even further: it wants to decarbonize almost its whole economy—not just the power sector—by 2050. Meeting these targets will require extensive efforts across sectors (including power, transportation, industry, and building heating), successful bets on technology, and complex policy changes that incorporate market incentives, costs, customer acceptance, and electrical interconnections with adjacent regions.

[Be sure to follow the link in that para].

Models figure prominently in the plan.

To understand the implications of New York State’s aspirations on its energy infrastructure, we simulated the performance of the power-generation and -transmission system in hourly intervals to 2040. The goal was to suggest what investment and system changes it would take to meet the state’s decarbonization goals for the energy sector cost-effectively and while maintaining grid reliability (Exhibit 1).

We can do that too. People at the University of Sydney have a model to show that NSW can easily go 100% RE with a multitude of small pumped hydro schemes! Several other campuses have similar groups at work. Expect to hear more from them when discussion of the “four icebergs” problem gets into the public debate.

    I thought dams were supposed to be bad?

    A flow chart of the modelling would involve numerous magical boxes.

    From the last link:

    At the same time, the incremental investment required to achieve 2030 emissions targets is significant: roughly $50 to $200 per metric ton of CO2 equivalent. However, all opportunities provide a positive return on investment in the mid to long term, whether through direct cash flow for investors (for example, in the case of renewables and efficiency improvements) or broader boosts to economic activity in the city (for example, transit-oriented development). For many opportunities, up-front investments are paid back within five to ten years.

    Spot the internal inconsistency.
    Pay more and boost economic activity. Pay$200/t CO2 equivalents !
    Magic box.

    Amusing that Audrey Zibelman announced her impending move to Google…

    Good riddance.

  5. Ms Zibelman has signed more than enough documents to be subject to the trillion dollar global warming fraud class action in 2030.

    How appropriate that AEMO head Zibelman moves to Google’s Space X business. One could suggest that the AEMO board are already in space under her direction, with nary a word about the potential dangers ahead for the power sector due to a protracted recession from COVID – not from the disease, but from the crushed economy.

    Ever increasing subsidised renewables means ever increasing electricity prices and ever increasing grid instability. You would think recession-subdued power demand and the coming shuttering of the aluminium industry in Australia would translate to lower prices – you know, supply and demand – but you would be wrong. Renewable projects require a minimum electricity price be maintained at all costs – lest those projects fail – if government doesnt stump up more subsidies. And the federal government continue to allow generators to deliberately mothball baseload stations in order to maintain high prices and high profits. ACCC where are you?

    And Audrey and her AEMO board know all this. A good time to her to leave and allow someone more grounded (electrical joke) to bring AEMO back into the real world and capable of tackling the formidable problems ahead. Expect more of the current board to bail as well.

    DaveR, you are more than a little confused. Google X has nothing to do with Musk’s SpaceX.
    Google X is trying to make renewables work. A few years ago they concluded they could not.

    Frontier Economics MD said – “I think it is time that we have a respected competent engineer running AEMO, not someone with an agenda”. Hear, hear to that but also add to that “sensible and altruistic”.
    Does such a person exist and where has that person been hiding?
    Danny Price also said “Good riddance. the board should follow”. Hear, hear to that as well.
    We need leadership across the spectrum that says – “When China starts demolishing its coal fired power stations, we will follow”. To do otherwise is to commit Seppuku.
