as a result the annual capital repayments which represent the majority of the lifetime costs of a renewable energy plant when spread over a shorter term of a ppa would be significantly higher than when spread across the longer potential operating horizon of the asset this can be done by redeploying the renewable energy asset elsewhere upon the closure of the mine however relocation of solar and wind system is often uneconomical given high disassembly transport and reassembly costs besides the cost of the technology itself the risk of stranding the renewable energy assets due to their limited redeployability may therefore create a barrier to their increased uptake in mining activities arena
