電気料金の請求書 stacks three Sino-Japanese compounds: 電気 (electricity) + 料金 (charges/fees) + 請求書 (invoice/bill). This kind of compound-noun chaining is typical of formal or administrative Japanese. 受け取る ('to receive') is a compound verb that's more specific than もらう — it implies physically receiving a document or item.
