Brief:
A latest briefing from the Lawrence Berkeley National Laboratory unveiled a noteworthy pattern: hybrid energy vegetation constituted a staggering 55.2% of the lively bulk photo voltaic capability and 51.7% of the bulk energy storage capability inside the U.S. interconnection queue by the shut of 2023. This evaluation, which targeted solely on amenities with a capability surpassing 1 MW, underscores the shift in direction of hybridization in the energy panorama.
In distinction, hybrid vegetation captured a marginal 14% of lively wind technology, a slender 12.4% for gas, and a good tinier fraction for different technology varieties pending interconnection.
- Joe Rand, an Energy Policy Researcher at LBNL and co-author of the briefing, highlighted in a September 30 webinar that the incentives of the Inflation Reduction Act geared toward standalone energy storage installations did little to curb the burgeoning curiosity in hybrid amenities all through 2023.
Insight:
The findings reveal that solar-plus-storage amenities emerged as the overwhelming frontrunners, accounting for over 92% of all proposed hybrid bulk energy tasks and 86% of the identified hybrid bulk technology capability inside the interconnection queue at the finish of 2023. With 2,532 bulk solar-plus-storage proposals listed, these tasks collectively aspire to ship roughly 575.5 GW of producing capability, with round 95% aiming for operational standing by 2029.
Following the solar-plus-storage pattern, proposed wind-plus-storage and mixed wind-solar-and-storage tasks trailed considerably, making up simply 5% (35.3 GW) and 4% (26.2 GW) respectively, spanning 80 and 48 separate initiatives.
“Undeniably, solar-plus-storage is the predominant configuration in the queue,” Rand asserted.
Momentum for solar-plus-storage installations surged dramatically, significantly from 2020 onward, eclipsing different configurations like nuclear-plus-fossil and numerous fossil-plus-solar mixtures by 2022, in line with the briefing.
The interconnection queue illustrated a vibrant panorama in 2023, witnessing an 18% improve in hybrid vegetation and a exceptional 33% uptick in total producing capability. Notably, hybrid proposed storage capability swelled by 48%, whereas standalone proposed storage capability surged by 52%.
Throughout 2023, the U.S. launched 80 new hybrid energy vegetation, boasting 7.9 GW of operational producing capability alongside 11.6 GWh of operational storage. Year over yr, the hybrid depend ascended by 21%, producing capability climbed by 19%, storage capability skyrocketed by 59%, and storage output potential skilled a shocking 67% increase.
Solar-plus-storage programs had been answerable for including a lion’s share of latest vegetation—66 out of the whole—and at present embody 288 of the 469 hybrid installations throughout the United States, with Arizona (16) and California (15) as the main states.
“This year has been particularly eventful for activity in the Southwest,” famous LBNL analysis scientist Will Gorman throughout the webinar.
Energy storage is notably extra pronounced in areas with heightened renewable integration. For instance, each the California Independent System Operator (CAISO) territory and non-ISO areas of the Western Interconnection mirror a median storage ratio of roughly 50% for current solar-plus-storage amenities, with proposed tasks reaching a formidable ratio of 100%.
Hawaii exemplifies this pattern, at present boasting a storage ratio nearing 100%. Rand commented, “It’s reasonable to postulate that upcoming hybrid plants will exhibit a relatively higher proportion of storage compared to their operational counterparts.”
Hybridized amenities symbolize not less than one-third of whole proposed photo voltaic capability in a number of critically necessary grid areas: 98% in CAISO, 81% in the non-ISO West, 49% in the Electric Reliability Council of Texas (ERCOT), 35% in the Midcontinent Independent System Operator (MISO), and 34% in the non-ISO Southeast.
The LBNL briefing additionally delved into 105 lively and creating energy buy agreements (PPAs) involving solar-plus-storage turbines, primarily concentrated in Hawaii, California, New Mexico, and Nevada. It revealed a notable rise in PPA pricing on the mainland from 2019 to 2024, significantly for amenities boasting storage ratios near 100%.
Due to the time-intensive nature of negotiating PPAs, the pricing evaluation by LBNL doesn’t totally seize the latest downturn in lithium-ion battery costs, a degree Gorman emphasised throughout the webinar.
Nonetheless, the rising demand for steady, lower-carbon technology could play a task in the not too long ago noticed hike in PPA pricing for hybrid amenities, Gorman elaborated.
- “PPA pricing is a multifaceted issue that extends beyond mere raw material costs,” he defined. “When demand for these resources soars, suppliers may have the leverage to set higher prices.”
