On May 1, Federal Reserve Chair Jerome Powell offered a two-part message to eager interest rate watchers. The Fed is unlikely to increase interest rates this year, but policymakers there are also not rushing to cut them from 5.25%-5.5%. “I don’t know how long it’ll take,” Powell said of when the Fed might cut rates.
Interests rate shape markets, and that’s especially true with renewable energy. Clean energy projects typically have high upfront costs, but are cheaper to run than their fossil fuel counterparts because they don’t require operators to continually purchase fuel. As a result, the price of clean energy is to a significant extent determined by the cost of the debt that developers take on when they first build the project.
Energy experts sometimes refer to what they call the levelized cost of electricity, or LCOE, to compare the cost of generating electricity over the lifetime of different facilities or energy sources. That figure incorporates all of the different costs associated with building and operating a plant from development to decommissioning. An April analysis from research and consulting firm Wood Mackenzie found that a 2-percentage point interest rate increase would lead to as much as a 20% spike in the LCOE for renewables. Power plants running on natural gas face only a 11% increase in the LCOE under the same interest-rate conditions.
At the same khbrknews, large oil and gas companies have enjoyed record profits over the last several years, giving firms deep pockets and leaving them less reliant on debt to finance projects.
The challenge that interest rates pose to renewable energy isn’t new. Indeed, it’s been a key point of discussion in energy and climate circles since inflation began to rise rapidly post-COVID. But what is new is the prospect of a longer period of sustained high interest rates. Billions in renewable energy projects have been announced in the khbrknews since the passage of the Inflation Reduction Act, but many projects…
