I don't think that any further interconnectors will be cheap, as I understand it the Kent Loop of the super grid is more of less at capacity because of the risk of a fault disconnecting one leg of it. This was I think the rationale behind the second French Interconnector going to Hampshire.
But Hinkley Point is not programmed to reach full capacity until late 2028 at the earliest. Most of the AGR fleet will have been long gone by then. Is there actually a timescale for Sizewell C once (if) it gets approved?
Two new interconnectors are due online this year/next year - 1.4GW North Sea Link to Norway, making using of green (cheap) hydro power and a 1GW through the Channel Tunnel. National Grid has a plan to construst several more precisely due to unreliability of renewables. Grid constraints are certainly an issue in GB though. When it's windy, wind is often curtailed because it can't be transferred sufficiently north to south.
