I'm no electrician, but when we built and welded a large water tower in our backyard, our welder needed 220. We only have 110 coming into the house. So, he grabbed a wire from the main line and somehow put the two lines together to get 220 so he could weld.
Our neighbors live in a tiny shack with a couple of light bulbs and a small refrigerator that they unplug at night. Since they use very little electricity, their bill is always under 250 cords a month.
We lived with a broken meter for 6 years. So we had to bypass the meter to get electricity into our house. The meter reader would come to our house every month and read the same numbers every month. It took over a year after we put a work order in for the electric company to install a new meter. As a result, our electric jumped from 150 cords a month, to 1,200 cords a month. We don't have air-conditioning...only fans, a refrigerator, and lights. Our friends who live in Granada run an air-conditioner in their bedroom. Their last bill was over $350 dollars, not cords.
In April, the electric rates jumped up over 7%. Like Dolly says, it depends on your location. And when our community transformer broke, we all had to pitch in and buy a new transformer from the electric company...over $2,000. I think they took a new transformer from a neighboring town to give to us. The electric company, Union Fenosa, pulled out of Nicaragua because they were losing too much money. It's common for many people to throw a wire on the main line and steal the electricity for their homes.
