HOME / world''s first large scale semi solid state bess power plant
Tashkent, Uzbekistan, May 21, 2024 — The World Bank Group,Abu Dhabi Future Energy Company PJSC (Masdar), and the Government of Uzbekistan have signed a financial package to fund a 250-megawatt (MW) solar photovoltaic plant with a 63-MW battery energy storage system (BESS).
On the BESS site, an on-site diesel generator will be used for power generation. The Project Company established for the project implementation currently employs a total of 23 employees, 11 of whom are Uzbekistan nationals. The EPC Contractor appointed for projection construction works is China Energy Engineering Corporation (CEEC).
Uzbekistan is amongst the fastest growing economies in the Central Asian region, with an increasing demand for energy. By 2018, the country's power consumption reached 50 million TWh, and the domestic demand for power has been projected to rise at an annual rate of 4%, due to continued population growth and industrial expansion.
In December 2022, severe grid congestion ensued from widespread spikes in electrical demand for domestic heating under extreme winter temperatures, culminating in series of power blackouts across Tashkent Region. The emerging power crisis in Uzbekistan has prompted an urgent agenda for the development of the country's renewable energy base.
UPS systems are cheaper upfront. But their batteries wear out faster and aren't designed for daily use. BESS systems are more expensive initially, but they offer long-term savings through energy arbitrage, grid incentives, and durability (especially with lithium iron phosphate batteries). Which One Should You Choose?
The purpose of an uninterruptible power supply is to protect whatever is plugged into it. For a PC user, this means your PC and your monitor. For a console gamer, this means your console and possibly your TV, though you can safely turn off modern consoles using only the power button, unlike with desktop PCs.
They use UPS for surge protection and instant switchovers and BESS to run for 8+ hours during blackouts, powered by solar. The company uses BESS to flatten peak loads and reduce utility bills by 25%, while UPS protects conveyor belts from sudden shutdowns. UPS and BESS both play critical roles, but in different ways.
An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
The system remains in standby mode, monitoring the main power supply. When it detects a power failure, the UPS switches to backup power from the battery within milliseconds. Best For: Low-power applications, such as home computers, gaming systems, small office equipment, and personal devices.

Which One Should You Choose?
For large power units, dynamic uninterruptible power supplies (DUPS) are sometimes used. A synchronous motor/alternator is connected on the mains via a choke. Energy is stored in a flywheel. When the mains power fails, an eddy-current regulation maintains the power on the load as long as the flywheel's energy is not exhausted.
