If you're worried about power failure for ten days then I recommend buying a $20 portable camping stove and three bottles of gas for about $1 each. Each bottle burns on high flame for about 80 minutes, so you'll be able to heat baked beans or cans of stew for a hot dinner.
Also buy some tea light candles, a torch and a small portable radio so you can listen to local broadcasts about what is happening. The cheapest tea lights burn for at least two hours, but you can get better quality, taller once that burn for eight hours.
If you're new to prepping, I'd recommend you buy cans of baked beans or stew or chili con carne, some canned vegetables like peas and carrots, ramen noodles, peanut butter, milk powder, breakfast cereal, instant coffee. Instant gravy with instant mashed potato with a pinch of white pepper and a slice of buttered bread makes for a quick meal too.
Rice is good, but you'll need to learn how to cook it using the camp stove. This is how I do it, but measurements will vary based on the size of your pot and if the lid has a steam hole and your stove: for one serving, combine 50g of dry rice with 100g of cold water in a pot. Cover, bring to the boil and immediately reduce the heat to VERY low (10%) for 16 minutes. Remove the pot from the heat but don't open the lid and allow it to finish absorbing the water for 20 mins and then break it up with a fork. Experiment a few times unlit you get the measurements right to there's no rice stuck to the bottom (you need more water) and it's not to mushy (you need less water). 16 minutes of flame might seem wasteful, but it's only at 10% lowest flame so it's the equivalent of less than 2 minutes.
I only mention rice because it stores well, can be cooked with very little gas and it'll bulk out most meats like canned stews and soups.
