Is overnight charging always cheaper for Jordan telecom sites?
For an account billed on the published three-period telecom tariff, the overnight period is cheaper than the evening peak but more expensive than the off-peak morning-to-afternoon period. Use the account’s confirmed tariff calendar, rather than treating “night” and “off-peak” as interchangeable.
The EMRC electricity tariff guide, section 15 on printed page 9, lists the telecom rates below. Printed page 13 defines the periods. The guide takes effect from January 1, 2025 until a date determined by the commission; September 21, 2026 is this article’s review date, not a new tariff commencement date.
| Jordan local-time interval | Published period | Telecom energy rate |
|---|---|---|
| 05:00–14:00 | Off-peak | 132 fils/kWh (JOD 0.132/kWh) |
| 14:00–17:00 | Partial peak | 142 fils/kWh (JOD 0.142/kWh) |
| 17:00–23:00 | Peak | 152 fils/kWh (JOD 0.152/kWh) |
| 23:00–05:00 the next day | Partial peak | 142 fils/kWh (JOD 0.142/kWh) |
Which electricity tariff applies to a telecom site in Jordan?
Match the electricity subscription to its billed category and the distributor’s confirmation. EMRC’s telecom provision covers telecommunications companies licensed by the Telecommunications Regulatory Commission, including their branches on single- and three-phase supplies. That description should be checked against the actual subscriber and connection, especially where a tower company or property owner buys the electricity. The useful starting file for a Jordan telecom tariff review is a recent bill tied to the meter serial number, account holder and physical supply point. Add the current contract or subscription record, the tariff code, and interval data where available. A screenshot of a national rate table cannot establish which subscription supplies the cabinet. Three common arrangements need different checks:- A direct operator account can be reconciled against the telecom category and the periods actually billed.
- A tower-company or shared infrastructure account needs its own classification confirmed. Do not infer eligibility from the tenants’ licences.
- A landlord supply with an internal submeter needs both the utility billing basis and the lease’s energy-recharge terms. A fixed private recharge price may pass through none of a time-shifting benefit.
Separate recovery charging from optional energy shifting
A battery drawing power from the grid can be doing several different jobs. Recovering after an outage restores a service capability. Maintaining the battery within its specified operating regime preserves readiness. Deliberately cycling storage to avoid an expensive period is an economic choice. These jobs should not inherit one permission simply because they use the same charger. Define the scope of the proposed change in one sentence: for example, “move only the discretionary charging tranche after the protected reserve has been restored.” Then identify who has accepted that tranche as deferrable. A financial model should not create spare battery capacity that the operations team has already allocated to continuity. For a site with solar, determine what the proposed grid charging would displace. Filling the battery early in the cheaper window may leave less room for later PV output. Conversely, waiting for forecast sunshine may be unsuitable when the actual array output is low and the reserve needs recovery. Evaluate measured grid imports, PV use and battery state together; do not credit the same energy as both avoided grid charging and solar absorption. A complete source-priority sequence belongs in the telecom energy management and source-control guide. Here, the required output is narrower: an account-specific permission for optional charging windows, with a clear route back to the accepted recovery policy.When should a telecom site recharge despite the higher rate?
Recharge at the permitted rate when delaying would violate the site’s approved reserve or recovery requirement. A tariff preference must yield to those operating requirements and to equipment limits. This does not mean commanding maximum charging current; the available supply and charger may impose a lower limit. Consider a fictional site that regains grid supply at 19:00 after using its backup reserve. The low-price band begins the following morning. Whether it can wait is a continuity decision, not an inference from the rate table. If reserve restoration is required before then, the approved recovery action takes priority and its energy cost is recorded as necessary operation. Before permitting a delay, the responsible engineer should confirm the battery charging schedule against current usable reserve, expected load, the accepted recovery deadline and the availability of other qualified sources. Confirm that battery temperature and BMS permissions allow the proposed charge. Nominal battery capacity and a displayed state-of-charge percentage alone are insufficient to approve the waiting period. The charging power also shares the connection with live telecom loads and supporting equipment. A price window does not increase the feeder rating, transformer allowance or rectifier headroom. Account for other loads on a shared supply and use the accepted charge limit. If that limit prevents completion inside the preferred period, compare a longer permitted session with a revised plan rather than increasing current beyond the design. Specify the response to an incomplete session. A missed cheap window should not cause the controller to keep deferring recovery from day to day. Define the point at which the normal recovery policy resumes and require the event record to explain the override. The wider outage boundary is covered in the telecom battery backup and grid-outage guide.Price the energy at the meter, then check what changed
Use metered charging energy at the relevant utility import boundary for a tariff comparison. Battery-terminal energy and utility-meter energy are different quantities. Charging losses, conversion paths and auxiliary consumption can change the purchased energy required for the same useful battery recovery. For an arithmetic illustration, suppose an eligible account can move a genuinely deferrable 20 kWh of measured grid import wholly from the peak band to the off-peak band. Assume the two sessions provide the same useful recovery, import the same energy and leave the remaining site operation unchanged.
Energy-charge comparison for this fictional sessionPeak: 20 kWh × JOD 0.152/kWh = JOD 3.040
Off-peak: 20 kWh × JOD 0.132/kWh = JOD 2.640
Difference in this energy-charge component: JOD 0.400
The 20 kWh assumption refers to grid import, not battery nameplate capacity or energy delivered during an outage. The comparison excludes other invoice items and does not establish the saving on a whole bill. If the new session imports more energy, recalculate it from the actual metered amount before making a cost claim.
Adding an extra discharge-and-recharge cycle is a different proposal. It introduces another energy path and additional battery use. A price spread alone cannot establish whether that cycle is worthwhile after conversion losses, auxiliary energy, degradation and implementation cost. Obtain the relevant equipment data and assess that proposal separately; do not apply the equal-import illustration to it.
Likewise, changing only the clock time cannot reduce a flat energy charge when the bill has no time-dependent component and the purchased energy is unchanged. Other operational reasons may still justify the move, but the proposal should identify those reasons instead of assigning a tariff saving that the account cannot receive.
Test one billing boundary before rolling out a template
First produce a read-only comparison using existing interval records: place each recorded import interval in its billed period and reconcile the result with the corresponding invoice energy component. Resolve missing intervals, multipliers and estimated readings before treating the reconstructed total as a baseline. Make the utility meter’s time basis explicit. The controller, site logger and billing export may display different time formats. Confirm how timestamps map to Jordan local billing time, whether interval labels mark the start or end, and which period receives an interval at a boundary. Do not compensate for an unexplained discrepancy by shifting data until the bill appears to match. For an approved limited trial, retain comparable starting and ending reserve conditions and log the reason for every charging override. Record total grid imports as well as the charging branch, because an apparent saving on one branch can be offset elsewhere. Note changes in traffic load, cooling demand, solar production and outages that limit the comparison. A charging window is ready for wider use when its rate mapping is correct, its recovery obligations are met and the observed meter record supports the claimed effect. A controller screen showing the right schedule is only configuration evidence. It does not show that the meter allocated the energy to the intended band or that the battery reached the required condition.- Check a transition into and out of the preferred band against the logged meter time.
- Verify the approved override when reserve recovery cannot wait, using an agreed test method that preserves service.
- Confirm behaviour when the tariff schedule or clock data is invalid; optional cost optimization should follow the approved fallback.
- Compare the trial’s energy allocation and recovery result with the agreed baseline, documenting exceptions.
