Load-shedding in Nepal is currently pretty bad.
Check out the website of NEA (Nepal Electricity Authority) for the most recent load-shedding schedules: in the upper-right corner.
Sometimes there are some areas where loadshedding isn't applied.
Most times this is if high-level politicians move into an area or if new ones have been elected. Quickly they will then get their own feeder line though, and the area is again on the regular schedule. You can expect this to happen within half a year or something.
Other areas that are on different load-shedding schedules are appointed industrial areas. These get continues feeds for a certain amount of time, say Monday to Thursday or Friday, and then no power for the rest of the time. Â
The only exception to this are areas that generate their own electricity and are as a whole not connected to the National grid. These are mostly remote areas, far outside Kathmandu valley.
Load-shedding can be dealt with by using inverters (UPS) which store electricity in batteries and release it during power outages, although when the number of outage hours is more then the number of hours when you can take electricity from the grid, inverters are of limited use. They then just don't have enough time for recharging the batteries anymore. Inverters are clean, noiseless and inefficient. The batteries need a lot of maintenance to keep working during high load-shedding hours, this is really taxing for the batteries. My inverter runs currently at 68% efficiency, AC to AC (on paper is was 98% efficient - at full load! - which it can only maintain for 2 hours at most before the batteries would be depleted). You'll be hard pressed to find a more efficient one. To coop with 12 hours of load-shedding you need to over-size your inverter and have it run at only 10 - 20 % of it max. capacity).
Hence the generator. Smelly, noisy and also expensive in fuel consumption. That is... if there is fuel available. The last half year we haven't really had too many fuel shortages, but the year before there were extensive periods (many weeks in a row) when there was not enough fuel (diesel / petrol / kerosene) to go around for all. This resulted in long queues at the petrol stations, and limited distribution when there was some petrol available. Not a good situation if you want to run of a generator.
Solar panels are an option, if your electricity consumption is relatively low. You can run a TV and a couple of CFL lights of a decent solar panel setup. Don't expect it to power your refrigerator though, but you might be able to have it power your laptop.
