Street lighting dispatch control is remote control, electricity metering and monitoring of a community's outdoor lighting networks from a single web panel. The core of LK Energy's solution is our own device, SvitloZir: designed and manufactured in Ukraine, it is installed in a standard outdoor lighting control cabinet and, together with the LK Energy cloud panel, forms an automated outdoor lighting control system (ASUZO). The utility operator switches lines on and off from a smartphone, sees the consumption of each line, and learns about faults before residents do. We are both the device manufacturer and the EPC contractor: everything turnkey, from survey to service.

Why "unmanaged" lighting is expensive

Wasted operating hours: Manual switching and simple timers cannot keep up with the length of daylight — the community pays for lines running extra hours.
Metering in the dark: Readings are taken by sending someone out to the cabinet — nobody sees the lighting network's actual consumption.
No way to know if it turned on: The service has no visibility into whether a street is lit tonight: a dark street or a faulty section is discovered only when someone calls to report it.
Network condition is invisible: Monitoring on outdoor lighting networks is almost nowhere to be found: nobody tracks line voltage and current — problems build up until something fails.

The solution: the SvitloZir device

SvitloZir (model EC-001) is a street lighting dispatch control device of our own design and manufacture, made by Lk-Energy LLC, Odesa. It mounts on a DIN rail inside a standard outdoor lighting control cabinet (ShUZO) — in most cases the existing cabinet is enough, with no need to replace equipment or luminaires.

Remote control: switching lighting lines on and off from the web panel or a smartphone.
Technical electricity metering: for each lighting line (per phase) in real time (kWh) — measurement modules with current transformers, with no need to break the circuit.
Network condition monitoring: voltage and current of each phase online.
Automatic schedule-based control: an astronomical lighting timer (the server calculates sunrise and sunset for the site's coordinates) or a fixed schedule.

A separate loop handles fault monitoring: phase break, overload, loss of load on a line (a sign of a faulty section), critical temperature, loss of connection. Every event is logged and appears on the operator panel immediately. In tenders, this class of solution is called ASUZO, an outdoor (street) lighting control system, or "smart street lighting."

What the community gains

Energy savings: an accurate schedule with no wasted operating hours on any line.
Fewer crew callouts: readings, network condition and control are all remote; a site visit happens only when it's genuinely needed.
Visible confirmation the lights are on: each line's load on the operator panel: whether the lighting came on is visible immediately, with no need to drive around or wait for residents to call.
Fast response to faults: a faulty section appears on the panel before residents report it.
Transparent metering: consumption data for each lighting line for the community's energy monitoring.

How the system works

Data flow: control cabinet → SvitloZir → GSM/LTE → cloud server → the operator's web panel or smartphone. No Wi-Fi or router is needed: a nano-SIM is installed and tested at the factory, and the channel is encrypted (WebSocket over mTLS). Telemetry reaches the server every 5–15 minutes (the interval is configurable); operator commands typically reach the device within seconds — usually under half a minute.

Scheduled: astronomical or fixed time.
Manual: the operator controls it from the panel or a smartphone.
Autonomous: if connection is lost for more than 15 minutes, the last schedule is followed; after connection is restored, it auto-syncs.

If power is lost, all relays open — the lines are de-energized until power is restored (standard fail-safe behavior: no uncontrolled switch-ons). Switching capacity is up to 10 A per channel; intermediate contactors are installed for higher-power lines.

What's included in the turnkey service

Survey of the outdoor lighting networks of the local government (OTG) or utility: cabinets, lines, operating schedules.
Design solutions per DBN B.2.5-28:2018 (Ukrainian building code) and DSTU EN 13201 (Ukrainian national standard).
Installing SvitloZir in existing cabinets; new control cabinets of our own manufacture where needed.
Setting up schedules, fault alerts and the operator panel.
Training utility staff to work with the system.
Manufacturer's warranty and technical support; remote OTA firmware updates — new features with no site visit.

Savings and payback

According to international community lighting modernization programs (including NEFCO projects in Ukraine), replacing DRL/DNaT lamps with LED delivers 50–70% electricity savings. The contribution of dispatch control itself depends on how far the current schedules deviate from the astronomical calendar: every extra hour a network runs is a direct overpayment. Advertised figures of "up to 90% savings" usually describe the combined transition of "old mercury lamps → LED + control."

We do not promise a fixed percentage: savings depend on the condition of the networks, the schedules and the tariff. SvitloZir's payback is driven by two factors — the electricity the lines no longer consume during wasted hours, and fewer crew trips to take readings and locate faults. We provide an estimated calculation for your network after the survey.

Modernizing a community's street lighting in 2026 has real co-financing sources available: the national project of the Ministry for Development and the EIB for replacing street luminaires with LED, the NEFCO Green Recovery program, and municipal credit programs from international financial institutions. We help prepare the technical part of the application.

Frequently asked questions

Does the site need internet or Wi-Fi?

No. SvitloZir works over the GSM/LTE mobile network: a nano-SIM is installed and tested at the factory, and the communication channel is encrypted. No Wi-Fi, wired internet or router is needed in the cabinet — mobile carrier coverage is enough, even for remote villages and lines on the outskirts of a community.

What happens if connection or power is lost?

If connection is lost for more than 15 minutes, the device switches to autonomous mode and follows the last schedule it received — the lighting keeps working. Once connection is restored, data syncs automatically. If power is lost, all relays open: the lines are de-energized, and there will be no uncontrolled switch-ons.

Do the cabinets or luminaires need to be replaced?

No. SvitloZir mounts on a DIN rail inside the existing outdoor lighting control cabinet. The system can also be added to already-installed LED luminaires without changing them: the device controls the lines at the cabinet level regardless of the luminaire type.

How much extra does dispatch control save compared to switching to LED?

There is no universal figure, and we do not promise a fixed percentage. The savings come from an accurate astronomical schedule with no wasted operating hours and fast detection of faulty sections: the more the current schedules deviate from the actual length of daylight, the bigger the effect. We provide an estimated calculation for your network after the survey, based on real schedules and tariffs.

How does this help meet the requirements of the Law "On Energy Efficiency"?

Law No. 1818-IX requires communities to introduce energy management systems and develop local energy plans. SvitloZir provides the factual basis for this: technical electricity metering for street lighting on each line, an event log, and consumption history. The energy manager gets the numbers without visiting the cabinets.

Where should a community start?

With a survey: we analyze the cabinets, lines and operating schedules, propose a configuration for the street lighting control system, and provide a preliminary savings estimate. Next comes a pilot on one line, to see the operator panel working on a real site, and then scaling to the whole community.

Order a SvitloZir demonstration or a pilot rollout on one lighting line in your community — you will see real consumption data on your own network. Leave a request — an LK Energy engineer will contact you and arrange the survey.
