Why does LKP “Lvivavtodor” ask businesses to join in providing backup power for traffic lights?
Specialists of LKP “Lvivavtodor” considered the following 4 options for the use of alternative sources of electricity for critical traffic light objects based on 8 hours of activity, but this requires from UAH 7.5 million to almost 20 million:
the purchase of industrial gel batteries will cost UAH 7,539,000 (the cost of one set is UAH 359,000),
lithium iron-phosphate batteries (LIFEPO4) in UAH 9,765,000 (the cost of the set is UAH 465,000),
lithium titanium batteries (LTO) in the amount of UAH 10,395,000 (the cost of the set is UAH 495,000),
solar batteries in the amount of UAH 19,950,000 (the cost of the set is UAH 950,000).
In the conditions of limited financing of LKP “Lvivavtodor” found an alternative solution – to use sources of alternative energy from legal entities and individuals located in the area of 1000 m from the necessary traffic light object. The company also announced the campaign “Help revive the traffic light – get a parking pass.” If you have suggestions, call the number: 0 800 303 007.
