At $0.79 per MWh (3/4 of a cent per kWh), yesterday was the cheapest daily average price for electricity in Alberta's power market history. By a wide margin! (And these are nominal prices, unadjusted for inflation...)

In 2024, investment is solar PV is set to grow to $500 billion, leading the transformation of the power sector More money is now going into solar PV than all other electricity generation technologies combined Learn more 👉 iea.li/3zxRsuC

When in Liverpool, it’s important to drop by Sir Paul McCartney’s childhood home, where so many legendary Beatles songs were written, and admire the solar PV system 2 houses down

When we @pembina proposed a coal phase out in Alberta in 2009 all we were told was why it couldn’t be done. Our biggest mistake was saying it would take longer than it did.

It’s a windy and sunny day in Alberta. Power prices are zero again.

Today, utility-scale batteries paired with solar PV are already competitive with new coal plants in some countries like India In just the next few years, batteries + solar will be cheaper than new natural gas plants in the US & new coal in China 👉 iea.li/3KeM9m3

Since 2010, battery costs have fallen by more than 90% — offering opportunities to cut emissions in road transport & electricity In 2023, electric car sales rose to almost 14 million. And battery storage deployment in the power sector more than doubled 👉 iea.li/3KeLWzh

The pace of the transition to EVs will hinge on their cost In China, more than 60% of electric cars sold in 2023 were already cheaper than conventional equivalents Competition & innovation are expected to bring down prices in other major markets 👉 iea.li/3JGhzkS

ERCOT hit a new record for battery dispatch tonight at 3.2 GW. This smashed the previous record set less than a year ago by over 1 GW (+47%).

Battery manufacturing capacity has more than tripled in the last 3 years Completing all announced projects would be enough to meet demand to 2030 on our net zero path But manufacturing is concentrated in only a few countries, creating supply chain risks: iea.li/4aQcy5g

In 2024, natural gas generation on an average April day in California hit a 7-year low. This is a significant trend reversal from what we saw from 2021 to 2023 in CAISO.

Interesting to see the different solar farm designs (tracking vs. high DC:AC) and their different levels of performance during partial eclipse in Alberta

The ERCOT grid set a new record today getting almost 73% of its electricity from wind and solar! Remember when some folks said 20% would break it?
