UK power group SSE announced plans to increase its multibillion-pound investment drive in clean energy projects and networks as it unveiled a near-90 per cent rise in full-year profits. SSE, one of Britain’s largest renewable energy operators, now plans to invest £18bn by 2027 and potentially as much as £40bn over the decade as profits climbed to £2.2bn, helped by higher electricity and gas prices. The FTSE 100 energy company’s investment injection is about 40-50 per cent higher than under previous plans outlined last year.
