Spain's power price concerns may get worse throughout peak solar season: Maguire

After a. breakneck growth that raised solar generation by over 200%. considering that 2019, Spain's solar installation rate looks set to slow in. 2024 as traditionally weak power costs mixed with high materials. and labour expenses eat into developers' returns.

The president of Spain's solar photovoltaic. association UNEF stated this week that installed capacity during. the first quarter fell by roughly 26% from the same duration in. 2023, across both domestic and industrial segments.

Fast renewable resource supply development, improvements to energy. efficiencies and contractions to energy use by industry have. helped drag Spain's wholesale power costs down roughly 90% from. their peak in March 2022 to multi-year lows last month - simply as. solar designers have actually included record generation capacity.

Power costs have staged a recovery this month on cuts to. generation from fossil fuels and the prospect of decreased future. solar setups, however might still come under fresh pressure. this summer when the nation's already-installed solar. facilities enter their peak output period.

RATE CUTS

Since hitting an all-time high of around 293 euros per. megawatt hour (MWh) in March of 2022, typical regular monthly wholesale. power costs in Spain stopped by over 90% to strike a multi-year. low of around 14 euros/MWh last month, according to LSEG.

This steep collapse in wholesale power rates made it. increasingly challenging for energy developers to chart a path. to future revenue, specifically provided the large upfront costs. involved in developing new energy projects and rising interest. rates which lifted borrowing expenses.

Slowing orders from property customers - due to lapsing. government subsidies and higher loan and funding costs - then. added to solar developer woes, and assisted set off the downturn. in setups noted by UNEF.

However although Spain's power prices have actually rebounded to over. 30 euros/MWh this month, a fresh push lower can't be eliminated. over the coming summertime.

PEAK PRODUCTION

Spain's solar properties produce more than double the quantity of. power throughout June, July and August as is created throughout winter. months, data from energy think tank Cinder shows.

In 2023, Spain's utility-scale solar possessions produced an. average of 4.85 terawatt hours (TWh) of electrical energy in June,. July and August, compared to an average of less than 2 TWh per. month in November and December that year.

The sharp climb in solar output in turn more than doubled. solar's share of the total generation mix from around 10% in. winter season to around 25% in July and August.

And in spite of the downturn in the pace of new solar. installations, the overall footprint of Spain's solar production. base struck a new high in 2024, and so will produce even greater. volumes of electrical energy this coming summer season.

Certainly, total solar production from photovoltaic assets. operated by energies through May 28 this year is roughly 13%. greater than throughout the same period in 2023, according to LSEG.

And so far in the month of May, solar output is 26.3% up. from the very same month in 2015.

This recommends that Spain's solar energy output over the. coming months will rise to fresh records during peak periods,. potentially exceeding system need requirements throughout spells. of weak intake.

This heavy load of solar power in turn has the prospective to. crowd out alternate power sources and drive Spain's power rates. lower once again, especially if domestic electricity demand stays. relatively flat.

Some of Spain's surplus power can be exported to. neighbouring nations such as France and Portugal, which were. both purchasers of surplus Spanish power earlier this year,. according to energycharts.info.

However, thanks to a recovery in France's atomic power plant. output and predicted output boosts from Portugal's own solar. properties, Spain may have a hard time to find all set buyers for all of its. surplus power this summer.

The unsold surplus may in turn weigh on local and local. power prices, positioning potentially fresh strain on the country's. beleaguered solar asset operators.
