PROJECT DEVELOPERS ARE BULLISH ON THE THERMAL ENERGY STORAGE MARKET

The power type of energy storage project refers to
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality.

What is an energy storage system?
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
What are the different types of energy storage systems?
In practice these systems can include ice storage systems that use electricity to freeze ice which can later be used to run a cooling system, or a heating system that heats bricks in a furnace to later provide heat to a building. Fuel cells: hydrogen fuel cells comprise a third category of energy storage system.
Why is energy storage important?
Energy storage serves important grid functions, including time-shifting energy across hours, days, weeks, or months; regulating grid frequency; and ensuring flexibility to balance supply and demand.
What is electrical energy storage (EES)?
Electrical Energy Storage (EES) refers to systems that store electricity in a form that can be converted back into electrical energy when needed. 1 Batteries are one of the most common forms of electrical energy storage.
What type of energy storage system stores electrical energy?
Electrostatic and electromagnetic energy storage systems store electrical energy, with no conversion to other forms of energy (i.e., stores as electric field). Capacitors, Supercapacitors and Superconducting magnetic Energy Storage (SMES) belong to this type of energy storage system (32).
What is mechanical energy storage?
Mechanical energy storage helps bridge this gap by storing excess energy generated during low-demand periods and releasing it back to stabilize the power grid, reduce peak demand, and provide backup power.

Spain hybrid energy storage power generation project
First solar plus battery energy storage PPA signed in the Spanish market will allow Zelestra to build a 170 MWdc solar and 400 MWh battery storage hybrid project to supply EDP. The construction of the hybrid project in Trujillo, Extremadura, Spain, will begin in the second half of 2025. [pdf]FAQS about Spain hybrid energy storage power generation project
What is energy storage in Spain?
It targets large-scale energy storage projects in Spain. It focuses on technologies like standalone battery energy storage systems (BESS), pumped hydro energy storage (PHES), and thermal energy storage. The program supports hybrid projects, which combine storage with renewable energy, such as solar or wind farms.
How many battery energy storage systems are in Spain?
More than 182 MW of the battery energy storage systems (BESS) highlighted in Spain’s Official State Gazette (BOE) are for hybridization with existing solar and wind generation capacity. From ESS News pv magazine España lists the most notable energy storage projects announced in Spain’s BOE in the fourth quarter of 2024.
How will Spain increase its energy storage capacity?
Spain has launched an ambitious €700 million (around $796 million) program to increase its energy storage capacity. This plan will add 2.5 to 3.5 gigawatts (GW) of storage. It includes pumped hydro, thermal energy storage, and battery systems.
Will zelestra build a solar & battery energy storage hybrid project?
First solar plus battery energy storage PPA signed in the Spanish market will allow Zelestra to build a 170 MWdc solar and 400 MWh battery storage hybrid project to supply EDP. The construction of the hybrid project in Trujillo, Extremadura, Spain, will begin in the second half of 2025.
How has Spain strengthened its energy infrastructure?
Spain has taken a decisive step in strengthening its energy infrastructure with the launch of a €700 million support scheme aimed at expanding large-scale energy storage across the country.
When is EDP launching a hybrid project in Spain?
The construction of the hybrid project in Trujillo, Extremadura, Spain, will begin in the second half of 2025. This leading product comes to address the significant market needs for reliability in Spain. The tailor-made solution gives EDP the flexibility to access clean energy beyond solar hours.
