Bulgaria borders on the western shores of the Black Sea, in eastern Europe between Greece, Turkey, Serbia, North Macedonia, and Romania. It has shaken off its past, and is reaping the benefits of belonging to the European Union, NATO, and the Council of Europe. With energy independence high on its agenda, it’s no wonder Bulgaria welcomes mega battery storage at this time.
Bulgaria Frames Applications for Mega Battery Storage
The Bulgarian Minister of Energy opened the bidding to supply bulk energy storage on 21 August, 2024. He called for tenders for 3,000 megawatts of bulk energy storage, that could be up and running by March 2026. Energy Storage news explains how this fits in the overall project to foster renewable electricity.
The day before the bidding window opened, Energy Minister Vladimir Malinov promised his government would contribute a total US$ 650 million to the construction cost. He stressed that his overall intention was to ‘guarantee the security and stability of the Bulgarian electricity system’ going forward.
The European Union will fund successful applicants under its RRF Post-COVID Recovery and Resilience Facility. Other similar projects include a €350 million scheme in Spain, and a €1.1 billion Hungarian government state aid plan. Will other nations follow as Bulgaria welcomes mega battery solutions at this time?
Are We Entering a New Era Of Mass Energy Storage?
Ten years ago most grid managers might have laughed at us, when we said we were entering a new era of batteries for utility grids. But now there are so many other options open, that batteries can mean more than just electro-chemical cells:
- Gravity batteries use excess energy by lifting weights. They lower these when demand is high, thereby releasing the energy.
- Hydro power does something similar by pumping water uphill. The cycle completes when it flows downhill again.
- Compressed air stores energy in underground caves. Then it releases it to rotate turbines and generate electricity.
There are so many more exciting options but we have run of time. When Bulgaria welcomes mega battery storage by awarding tenders, which energy storage option do you think it should choose?
