GC0142: Adding Non-Standard Voltages to the Grid Code

Following the rejection of modification GSR0021 to the System Quality and Standards of Supply (SQSS) by Ofgem, this modification is being raised to seek modifications to the Grid Code. A separate modification will be raised to modify the SQSS. The modifications are looking to incorporate equipment at nominal voltages other than those that are currently used within the Codes.
