I'd be surprised to see the scheme finish so soon. After all, it is a relatively cheap way to get rid of expensive top-of-the-scale ATCOs, with relatively-limited skills (within the NERC context). That way the cost falls on the pension scheme which can well afford it. The alternatives are 1) retain the ATCO on high salary until age 60 in a role with limited flexibilty, or 2) make him/her redundant with the major costs involved for someone with 30+ years' service. I'd think that the scheme will remain until NERC has well-and-truly "bedded in" and management can see exactly what staff they can do without. There again, I could be wrong . . .
