🌎 Spooky season for clean energy stocks #171

Lessons from recorrecting clean energy public markets


Happy Monday! 

👀 ICYMI, last week we unveiled Sightline Climate, our new market intelligence platform for the new climate economy. Built on the foundation of this newsletter, Sightline Climate’s subscription intelligence product goes beyond the inbox with data, tools, and frameworks to bring clarity to industry professionals navigating climate transition decisions. Think of it as your favorite deep-dives from the newsletter, 10x’d. More than 20 leading investors, corporates, and governments already use the platform including the US Department of Energy, BHP, and Galvanize Climate.

And now back to your weekly scheduled programming. The around-the-block line outside of Spirit Halloween reminded us that we’re getting shockingly (spookily?) close to the end of the month… Maybe trade in your Barbie costume to dress up as one of the newly delisted Endangered Species?

With spooky season upon us, clean energy stocks have plummeted 30% since the start of the year, driven by higher interest rates sending shocks through already fragile wind and solar supply chains. Plus, the US funds $3.5B for grid enhancements, Navigator CO2 cancels its midwest CO2 pipeline, and Germany switches on a 20 MW ‘river’ heat pump. 

In deals, $91M for a vertically-integrated European heat pump platform, $50M for direct lithium extraction, and Volta Trucks goes bankrupt.

Clean energy chills 30% this year

What goes up must come down. In the ESG exuberance of 2021 and 2022, public markets and institutional investors piled into public climate tech companies and prices (valuations) reached all-time highs. Now,  demand has quickly fallen off amidst the rapid run up in interest rates and supply / demand imbalances. 

The S&P Global Clean Energy and MAC Global Solar Energy indexes have swiftly dropped ~30% YTD, as the US 10 year treasury yield soared to above 5%. 

Over the past few months, higher interest rates coupled with recovering from post-COVID supply shocks created a snowball effect that set the clean energy market rolling downhill: 

  • On June 23rd, Siemens announced almost 15-30% of their installed wind turbine fleet was damaged or needed repairs.
  • On Aug 30th, Orsted warned it may write off ~$2B in impairments with many of its offshore projects experiencing severe supplier delays. 
  • On Sept 27th, Nextera Energy Partners revised its distribution per unit growth rate to between 5% and 8% through 2026, down from its previous target of 12% to 15%.
  • On Oct 20th, Solaredge cited weaker demand in Europe for “significantly lower” revenue expectations in Q4.
  • Earlier this morning, Li-Cycle announced its pausing construction on its major Rochester Hub battery recycling project which received a $375M conditional loan from the LPO.

Unpacking clean energy woes 

Higher interest rates = higher cost of capital. Renewable energy projects are particularly sensitive to interest rates, especially since most require debt to finance a high upfront sticker price for the tech. Higher interest rates lead to a higher cost of capital, making it pricier for developers to fund renewable energy projects and narrowing the spread between financing costs and the return on acquired or financed assets. 

Assets and liabilities mismatch. Renewable energy projects face an assets and liabilities duration problem. Renewable assets have a duration of ~30 years and are contracted for the first 10-15 years, but financed with debt at an average maturity of 7 years. This means existing assets developed and financed during a period of lower interest rates, could be uneconomic in today's current rate environment. 

Supply chain oversupply. The pendulum for clean energy supply chains has swung the other way. After wacky COVID supply chains and the Russia-Ukraine war drove supply shocks for solar components and battery materials, manufacturers and miners quickly built up capacity. Then supply chains normalized, and distributors were left holding the bag with anecdotes of 1-2 years worth of supply sitting in warehouses. Meanwhile, battery metals prices including for lithium carbonate have dropped 62% to $30 per kg since the start of the year.

Gone with the offshore wind. Offshore wind has been especially hard hit, facing longer development timelines, more complex supply chains, and contracts signed before finalizing costs and financing. Two years ago, companies were making plans for offshore wind projects on the Eastern coast of the US based on a projected cost of $77 per MWh - now that’s jumped 48% to $114, according to BNEF. Pile on top of that uncertain IRA tax credit qualifications, and Biden’s plan to deploy 30 GW gigawatts of offshore wind by 2030 is looking near impossible by the day. 

NEM 3.0. California’s latest net metering plan ‘NEM 3.0’ reduces payment for excess electricity from residential solar to the grid by 75%. The updated policy worsens the savings and payback period profile of residential solar, with residential solar developers like SunPower are feeling the punch.

Public to private takeaways

While climate tech public markets face more real-time valuation gyrations, private climate tech companies developing projects all experience the same underlying challenges. Capital is no longer cheap, and the founders and developers that succeed will go back to their excel drawing boards to make sure project economics work. Momentum swings will always happen, and marking deals at mid-cycle multiples would go a long way to ensure discipline longer-term.

In the News

The US made a $3.5B commitment to grid enhancements for 58 projects across 44 states in the largest ever federal investment in existing grid infrastructure. Projects range from new transmission lines and batteries in Georgia, to wildfire assessment and resiliency across Western US. 

Navigator CO2 Ventures canceled its Heartland Greenway pipeline project aimed at capturing 15 million metric tons of carbon dioxide annually from Midwest ethanol plants and storing it permanently underground. The company blamed its decision on "unpredictable" state regulatory processes.

Germany is providing further proof of concept that heat pumps work at the municipal level. One of Europe’s largest units just came online, providing 20 MW of output to a 3,500 household district bordering the Rhine River, from which the pump derives its thermal energy.

Hydrogen has found a new and exciting home in the power generation space. A consortium of German, UK and French energy component manufacturers alongside 4 European universities demonstrated the world’s first 100% renewable hydrogen gas turbine. The news comes just 6 months after a similar project showed promising results using a 30% hydrogen, 70% natural gas mix.

Climate tech investment has followed the public market down, but there are still bright spots. PwC’s annual State of Climate report found a 40% decrease in climate tech funding over the last year. Climate tech did nab a greater share of the total startup investment market, though, and drew plenty of first-time investors, showing the sector still has a good dose of gumption on the horizon.

Canada announced a new initiative called Radarsat+ for a $740M investment over the next 15 years in satellite technology to boost earth observation data used to track wildfires and other environmental crises.

Jigar Shah and the Department of Energy (DOE) are in the hot seat. In a congressional hearing last week, the Loans Program Office Director and senior staff were warned of potential for sloppy spending as the department begins to dole out loans from funds allocated to DOE by the 2022 Inflation Reduction Act (IRA). The warning came largely from DOE Inspector General Teri Donaldson, who voiced concern that funds could end up in the hands of Chinese or Russian companies. Some Republican senators pounced at the opportunity to call for a full IRA repeal, and flirted with accusing the LPO Director of corruption.

Scientists see net zero within reach by 2050 after new federal investments, a 700 page report by the National Academies of Science and Engineering found. A positive highlight to remember all of the work being put into the energy transition is paying off!

What’s holding back the uptake on heat pumps? Corporate consolidation, an aging workforce, and high costs top the list.

We need some serious steel in the ground to meet global climate targets… 80 million km of new grid, in fact.

Report finds that companies buying carbon credits off the VCM tend to be climate leaders, not greenwashing laggards.
