Cherkasy adds emergency power cuts at 08:52: mining plans need more than the hourly schedule
Source checked: 2026-11-02 · Editorial analysis published: 2026-11-02
The operator’s November 2 alert says emergency cuts apply alongside scheduled outages. The 06:00–24:00 restriction window is not eighteen hours without power for every address.
An emergency alert changes today's plan
Cherkasyoblenergo's official site says emergency power cuts were introduced across Cherkasy region from 08:52 on November 2 on Ukrenergo's instruction. The alert says hourly scheduled cuts also continue. For a home miner or a hosted machine in the region, that means today's published timetable alone cannot establish the hours the equipment will actually run.
The underlying November 2 schedule was published on November 1 at 20:25 and sets a restriction window from 06:00 to 24:00. The operator attributes the need to continuing attacks and the effects of previous missile and drone strikes. This is a new date-specific alert and schedule, not the October 27 notice previously covered by ASIC.tools. All times in this article are local to the region.
Eighteen hours is the window, not every address's outage
The published period spans eighteen hours, but different subgroups have different planned interruptions. In the cited timetable, subgroup 4.2 is listed for 12:00–14:00 and 16:00–18:00, four scheduled hours in total. Subgroup 1.2 has 06:00–08:00, 14:00–16:00, 18:00–20:00 and 22:00–24:00, eight scheduled hours. Neither example describes every household.
These are planned intervals in a dated source, not a guarantee of supply outside them. Emergency cuts are an additional operating measure and can change what happens at an address. The alert does not provide an end time for that emergency measure. We therefore do not turn either example into a promise of twenty or sixteen powered hours for the day.
The operator directs customers to its official queue and subgroup information and chatbots. Establish the applicable group for the actual connection rather than infer it from a neighbourhood screenshot or another building. A hosting provider may have a different connection and supply arrangement from a nearby home; the relevant evidence is the site's own service and operating record.
The operator also publishes subgroup lists for the winter period from October 1, 2026 to April 1, 2027. That list identifies the connection group; the separate daily notice says when that group is scheduled to be interrupted. The emergency alert adds a third layer. An address list alone is therefore not today’s supply timetable, and yesterday’s daily table is not automatically today’s plan.
Translate downtime into actual mining time
Mining output depends on work actually delivered. A machine disconnected from power does not keep producing at its rated hashrate, and reconnection may include startup and a delay before the pool sees normal submissions. A brief return of voltage is therefore not automatically a full productive interval in the pool's records.
For a farm budget, record actual online time and accepted work, along with the electricity used. Reduced runtime can lower the electricity bill while also reducing revenue; it does not automatically improve profitability. A fixed hosting payment or service charge may remain even when production stops. The schedule supplies context for expected interruptions, while actual records establish the result.
As a simple hypothetical example, two hours with a 3 kW miner fully unpowered means 6 kWh that this load does not consume. It also means two hours without that machine’s mining work; no saving should be counted without the missing production. The source does not say every machine experiences exactly that interruption. This is a way to account for an actual measured stop, not a prediction derived from the regional alert.
Keep essential backup power separate from mining
A small backup system that keeps a router or monitoring device alive should not be assumed capable of sustaining an ASIC. The miner, its power supply and required cooling must be considered as a load, with actual power and energy limits checked for the backup equipment. This article does not specify a battery size or suggest improvised electrical connections.
Maintaining connectivity can still help an operator distinguish a network fault from lost power, but an online router does not prove the miner is running. After supply returns, check the machine's status, cooling and accepted pool work using the normal equipment procedures. Repeated switching should not become a reason to bypass protection or operate equipment outside its intended conditions.
Read the live notice before the next operating window
The November 2 emergency alert is the important change: it sits alongside the previously published subgroup timetable. Before planning a restart or promising output, check the operator's current notice and the actual site's condition. This report records the alert found at verification; it is not a live availability service and cannot promise the time electricity returns.
For readers outside Cherkasy, the general lesson is how to read such a notice, not that this timetable applies to them. Keep the date, region, subgroup and type of restriction together. For miners in the affected area, use actual uptime and credited work in the calculation and treat a planned free slot as a plan that remains subject to emergency grid operation.
