Every change and every fix since this went up. The ones that could have affected you are first and in full; the rest are one line each. Entries are not dropped from this page as they get older, and none has been except two from this morning that described this page’s own layout and stopped being true by the afternoon.
Times we showed somebody a wrong figure, judged a correct bill incorrect, or kept or removed something without asking properly. In full, because if it was you, you need enough to tell.
A bill emailed to us could be lost if it arrived in the wrong second, and the sender would never have known. Twice in a day our mail receiver stopped and restarted, both times because a machine somewhere on the internet failed to start an encrypted conversation with it in a way it did not expect. Anything arriving in that moment went nowhere: no reply, no report, nothing to say it had happened. A connection that cannot be set up is now noted and ignored, and the receiver keeps answering everybody else. If you emailed a bill in the last two days and heard nothing back, please send it again.
A farm bill whose meter was not read is no longer told that we could not read it. On a metered agricultural connection MSEDCL sometimes issues a bill with the meter row left blank and both reading dates empty, because nobody read the meter that month. We refused three of those and said we could not find the reading dates, which reads as a problem with your copy and asks you to send a clearer one. Nothing you could send would have helped: the figures are not printed on the page. The page now says exactly that, and says plainly that sending the bill again will not change it.
A bill sent as a picture could be told it does not add up when the fault was ours. When a scan loses one line out of the charge table, we used to fill the gap with whatever figure sat nearest on the page and then report that the charges did not come to the total. It was found on a shop’s May bill that is right to the paisa: the amount payable by the due date had landed in the fixed charge’s place. We now require the charges to come to the printed total before we believe we have read them at all, so a table we cannot read is called unreadable rather than blamed on your bill. Only one month on our records was ever judged not to add up. It belongs to another connection and its document is long deleted, so we cannot go back and tell whether this was the reason.
A business bill sent as a photograph was refused, and now it reads. If you scanned a shop or office bill and were told it had been reported and that somebody would look at it, that was our fault and not a problem with your picture. Three things about a business bill differ from a household one, and all three defeated us. It prints its dates as 20-03-2026 where a household bill prints 24-OCT-25, and we only knew how to look for the second form. The row holding your meter readings comes back as stray marks and a lost figure when we read it the ordinary way, so we now read that row by where the figures sit on the page instead. And it names your connection type only once, because it carries no rate card on the back to repeat it in, where a household bill does. Your bill now reads, and every charge on it is checked against the approved rates for a shop under 20 kW. The caution that goes with it: this rests on two bills of this shape, from one shop, so treat the answer as worth a second look rather than as settled.
If your last bill was months old, your saved page invented a cycle that was not running. The picture of where this month is heading works out how far through a cycle you are. Where you had typed in a meter reading it refused to guess from a bill that was too old to mean anything, but where it was estimating from your own pace it never checked, so a bill from years ago was treated as if the cycle had begun the day it was issued. One page read 17,251 units so far and priced the next unit against it. Both halves now refuse the same way, and the page asks for a reading instead.
If you sent a bill we could not price, we told you we could not READ it. That was not true. We read it perfectly - what we did not hold was the approved rates for its month. So you were sent looking for a clearer scan that would never have helped, and told to try again in a day or two, when nothing was going to change. The page and the emailed reply now say which of the two it is, and how far back we can check. A bill sent by email got this wrong in a different way from one uploaded, and both now say the same thing.
If you live outside a municipal corporation, our estimate of your next bill was a few rupees too high. A connection inside a corporation pays a small fixed surcharge each month and one outside does not, and we were assuming everyone pays it. So a village connection's next-bill estimate ran a little high. We now read it off your own bill's printed fixed charge instead. One connection on file is outside a corporation, which is why this is marked: if the figures we showed you looked a few rupees off, this was why.
A workshop or factory month that did not add up was listed on your saved page as though it were fine. Your history page showed every business month as adding up, whatever our checks had actually found - so a month that does not reconcile sat quietly among the ones that do, and the one worth taking to your discom was the one the page said nothing about. It now says, on that month, that it did not add up, the same as a household bill does. If a month of yours we had shown as fine now flags, this is why.
A bill we could not read is now checked and added to your history as soon as we fix the fault, without you sending it again. When a bill defeats our reader we keep the document, with your permission, for exactly one reason: to find out why and put it right. Until now that is where it ended. We fixed the fault, deleted the document, and left you to notice and send the bill again, which we never asked you to do and never told you about. Now the moment the fix lands, the bill is read, your figures are filed as the month they always were, and only then is the document deleted. It is filed under the permission you gave when you sent it, and never for anyone whose connection number we do not hold.
A workshop or factory bill charged a flat monthly demand figure was told it did not add up, when it was correct. Some connections are charged a fixed amount each month for demand instead of a rate for every kVA. On those bills MSEDCL leaves the quantity box empty some months and prints a plain 0 in it others, on the same meter. We read that 0 as a real quantity, so we worked out that the charge should have been nothing and said three things were wrong: your demand charge, the minimum demand against your contract, and whether your rates are ones the regulator approved. One factory saw three of the months it sent judged this way. Send any of them again and it now reads correctly, and we have corrected our own record of them without being asked. Nothing about your bill changed; what we said about it did.
A rooftop solar bill printed as a table was refused, when it was correct all along. Some solar bills set out the meter as rows for Import, Export and Generation instead of one summary line. We read what the meter had drawn, compared it with the smaller figure you were actually billed for, could not see the export offset that explains the difference, and turned the whole bill away. The offset is printed on the bill and is now read from it. If yours was refused this way, send it again.
Two figures on your saved page disagreed about the same month. The picture at the top used the meter reading you sent; the next-bill figure below it ignored that reading and quoted a typical month, so the two could differ by forty units about one month, on one screen, with nothing to say which to believe. The next-bill figure now starts from what your meter says and adds the days still to come, so they cannot differ. It also says which part is measured and which is still a guess.
Forward a bill we cannot read and it is now kept and fixed, the same as one uploaded. Uploaded, we hold it so the fault can be found; emailed, we used to throw it away. It is kept now only once the reply telling you so has gone out. That reply says how to have it removed at once, and it goes on its own after 30 days.
Deleting your data now removes a connection number that used to be left behind. If we could not read your bill we keep it for a while to fix the fault, and our slower reader tries to read your connection number off it so we can ask whether it is yours. Deleting everything cleared the number you had confirmed and left the one the reader had read, on a page that says nothing identifying you remains. It was one number on one kind of record, and it is now removed with the rest.
A bill carrying a credit is no longer turned away, or judged wrong once it is read. Electricity duty is a percentage of your bill, but not of every line on it: if your bill carries a credit, the utility may not charge duty on that part. We assumed duty was always charged on everything. Against that assumption the sums on such a bill never came out, so we refused it outright and told the sender we could not read a bill that was perfectly legible. Behind that sat two more of the same mistake, which would have shown once the first was fixed: the duty would have been called wrong by about twenty rupees, and the bill reported as adding up to less than it does. All three are fixed, and the page now says which figure the duty was charged on rather than leaving you to work it out. This is for a bill sent as the file MSEDCL emails you: a PHOTOGRAPH of such a bill is still turned away, and we would like one to work from.
A demand-metered bill is no longer told its own demand charge is a hundred times what the bill says. If we cannot read your bill, a slower reader on our own machine tries it, and then checks the figures it read against each other. One of those figures, the rate charged per kVA of demand, was being carried in rupees where every check treated it as paise. So a shop or factory bill that was perfectly correct could be shown back to its owner saying something like "74 kVA at Rs 3.90 is Rs 288.60, but the bill says Rs 28,860.00" - on a page that calls those figures theirs. The two halves of that reader disagreed about one figure and had done since the second one was written. They agree now, and there is a check that fails if they ever stop.
A bill can no longer be refused for the way its Marathi labels happen to be stored. Every MSEDCL bill prints the same Marathi labels, but not every one of them stores those labels the same way inside the file: on some, the words are held in the order they are drawn on the page rather than the order they are typed. Nothing about the bill looks different to you. To us the words simply stopped being the words, so we gave up at the first label we look for and said the reading dates could not be found. The bill itself carried its readings, its rates and every charge, correctly and in plain sight. A bill like that was refused every time it was sent, and sending it again would not have helped. Those bills read now. Every copy we were holding because we could not read it is checked again whenever we fix something, and the ones that read as a result are deleted the same moment.
The slow reader no longer invents a total ten times too large. When a photographed bill defeats our reader, a second one reads it by where the figures are printed and asks a model about the cells it cannot make out. The strip of the page shown to the model was nearly two rows tall, so for the total it saw two numbers (a 0.00 from the row above and the real 22,416.19) and answered with a blend of them: ₹2,22,416.19, on a page that calls the figures yours. The strip is now sized from how far apart that very bill prints its rows, a model answer that wildly contradicts what was read off the page is believed by neither side, and the page for a held bill now adds the charges up in front of you so a wrong total has to argue with its own parts.
Two people who photograph their bills no longer end up sharing one record. A bill we cannot read is kept, and we tell the two apart by what is printed on them. A photographed bill has no readable text at all. So every photograph of a two-page bill looked identical to us, and every photograph of a one-page bill looked identical to us. The second person to send one had their bill quietly dropped in favor of the first, while the page told them theirs was being kept. It was not, and the reader kept working on somebody else’s bill instead. Photographs are now told apart by the picture itself. Bills already being held have been given their own identity too, so they stay findable by the people who sent them.
Nothing of yours is deleted now without being asked first. There were four ways to delete, and only one of them asked. A household bill with priced months got a page listing what would go. But a shop bill, a farm bill, a household connection whose months we had never managed to price, and a bill we were holding because we could not read it were all removed in the same moment the bill was uploaded, with no page in between and nothing to undo. Nobody chose that; they were separate paths that grew apart, and it was invisible from the outside because whichever door you walk through you only ever see one of them. Every door now shows the same page: what we hold, how much of it, and two clear choices.
“Nothing to delete” now means nothing. That page decided by counting your months. It was not counting the record of the connection itself (the PIN code from your bill, the category and load, when we first saw it, and your consent and when you gave it), nor a copy of a bill we were holding because it could not be read. So somebody could be told we hold nothing while all of that stayed, and a held copy could survive a deletion the page had promised would take it. All three are now checked, and all three go.
Two bills were reported as not adding up when the mistake was ours, and both kinds are fixed. If your billing period crosses 1 April, the monthly fixed charge on it is part old rate and part new: we were comparing it against just one of them, and calling the difference an error on your bill. And some bills carry a credit that electricity duty is not charged on; we were including it in the duty sum and then expecting the total to match. Neither was ever a fault in what you were charged: on both bills every line added up to the printed total exactly. If a month of yours was marked as not adding up for either reason, it is being put right without you doing anything.
A month we got wrong is now looked at again, and put right on its own. When a bill failed our checks we told you so and left it at that. And if the gap turned out to be ours, nothing ever went back and corrected it. Every time we fix our own arithmetic we now re-check every month we had flagged, using what we already hold, and quietly clear the ones that were never wrong. You are told nothing, because there is nothing you need to do.
A farm bill's reply quoted the wrong figure as the total. On a metered pumpset the state pays most of the bill, and the reply was quoting what was left after that as though it were the bill: on the bill we checked, Rs 660 against charges of about Rs 9,820. The three numbers are now separate and labelled: what the charges came to, what the state pays of them, and what is left for you to pay.
Rooftop solar bills are read correctly now. If you send power back to the grid, your meter moves more than you are billed for, and we were treating that difference as an error and refusing the bill. The units you export are now set off before anything is checked.
Deleting your history did nothing when you clicked the button in a browser. It works now, and it also strips your connection number out of any fault report we kept.
We now keep your PIN code, and nothing else from the address. It is how we will tell a hot month in your area apart from a bill that is genuinely wrong. The box you tick says so.
