1. The presently overall rated power capacity (Prtd) of the Tashkent city out-door lighting electric grid is 29469,0 kW .
Data about consumption, losses and saving of electrical energy in net-works of outdoor lighting is presented in annual balance of power consumption for 2009, you can see in the Table № 1.

1.1. From balance of power consumption we can see that the common expenditure of electrical energy makes 65548,5 GWh (50,9 %). The difference be-tween settlement expenditure of the electric power, for the given concrete working conditions of networks of outdoor lighting, and to actual expenditures under indi-cations of electric meters, defines the value of total losses (saving) of the electric power depending on factors of electro installations inevitably accompanying at maintenance including electric systems of outdoor lighting and makes 63206,2 GWh (49,1 %).

Ertd.year = Рrtd * t * 365
t - average daily time of outdoor lighting in hours (11 h.);
365 - quantity of days in a year.

Ertd.year = 32188,68 *4 000 = 128 754 720 MWh. (128 754,7 MWh.) .

2. Within the scope of project realization following activities are offered:
2.1.

Concerning offered lamps for using, they are power effective sodium lamps (50 W – 8000 pc., 70 W – 17 054 pc., 100 W – 43 904 pc., 150 W – 14 659 pc., 250 W – 22 028 pc., 400 W – 1 979 pc.), and metal halogen (100 W – 4 342pc., 150 W – 994 pc.,) with luminous efficacy up to 117 lm/W and above.

2.2. Replacement of existing feeding centers (FC) of different types (Ex-ecutive Point of Distributive Line - EPDL, Executive Point of Outdoor Lighting - EPOL, Outdoor Thyristor Distribution Box - OTDB and others) operated under cascade schemes of mechanical time relay and telecells on direct lines of tele-communication in quantity – 1546 pieces, to innovative system of outdoor lighting with software operation, equipment which has higher lighting parameters and de-sign. Offered lanterns of new generation with aluminum case, which have double level of protection, providing the maximum guarantee from dust and moisture hit under operating conditions in Republic of Uzbekistan and promoting substantial increase of service life of all lighting facilities as a whole.

2.3. Carrying out of energy audit, optimization of placing and choice of lighting devices will allow additional decreasing of power consumption up to 4 %.
