,ROW_NUMBER() OVER(PARTITION BY pl.PlanId ORDER BY xpl.PlanId) RN
FROM [dbo].[Plan] pl
JOIN [dbo].[Plan] xpl
ON pl.PPlanId = xpl.PPlanId
AND pl.Name = xpl.Name
WHERE

Can you show an execution plan of the query? Is that possible to rewrite the query as 
Sorry cannot test it right now
SELECT
PlanId
,ReplacementPlanId
FROM
(SELECT PlanId,Name,SDate,TypeId FROM [dbo].[Plan]) pl
CROSS APPLY 
 SELECT TOP (1) TypeId ,Live FROM [Plan] xpl
 WHERE  pl.PPlanId = xpl.PPlanId
AND pl.Name = xpl.Name
) AS Der
WHERE pl.SDate > (CONVERT(CHAR(10),DATEADD(M,-12,GETDATE()),120)) AND  
Der.Live = 1
AND pl.TypeId = 7
AND Der.TypeId = 7
