Solar and Wind farms cannot guarantee how much electricity they can generate in a day, week, month or a year. This is because there is no guarantee on sunshine or wind to provide this generation. The companies that build and own these facilities, would not do so unless they had a contract guaranteeing, as a minimum, a fixed annual return on their capital. So, what organization under writes this guarantee? Who pays for non-delivery of electricity when the wind doesn't blow? Has anyone seen a wind or solar farm contract? The cost of our electricity is to increase by over 50% in the coming 12 months. Why? Is it to cover the cost of theses wind and solar farm contracts and short falls in delivery?
