The 116-bed unit — which was moth-balled for months — is the second to start admitting patients in England, after Manchester's makeshift facility re-opened last month to provide treatment for non-Covid patients.
Bosses at Royal Devon and Exeter NHS Trust insisted the extra-capacity was needed because they are 'very busy'.
But NHS data reveals only 88 per cent of beds — or 647 out of 736 — were occupied on average in the week ending November 22, the latest for which data is available. Occupancy rates stood at 94.9 per cent nationally in the first week of December last year, and were at 95 per cent - or 744 out of 780 - at the trust.
There were 85 beds occupied by Covid patients on average in the trust in the seven-day spell to November 17, a 60 per cent rise on the previous week.
Covid infection rates in the South West as a whole have been among the lowest in the UK since September. In Exeter they fell 20 per cent in the week to November 20 to 98.1 cases per 100,000 people. This suggests pressure on hospitals will start to drop in the coming weeks.
Devon was placed under Tier Two restrictions today alongside its neighbour Dorset, but nearby Cornwall was moved into Tier One.
Health chiefs admitted today there was pressure at the trust's hospitals, and said they were also concerned about a case rate of 85 per 100,000 in the over 60s, who are more likely to be hospitalised with the disease.
Exeter's Nightingale hospital will start accepting patients with Covid-19 today, officials have said. It has been opened because local hospitals are 'very busy'
Exeter MP Ben Bradshaw said the move was 'very good news for patients'
Announcing the decision to open their Nightingale hospital a spokesman said: 'The Nightingale Exeter will accept patients Thursday who will be transferred from the Royal Devon and Exeter NHS Foundation Trust (RD&E) which is very busy.
'We would ask that the public continue to observe the Government’s advice on observing the lockdown and social distancing so that we can keep patients safe.'
MailOnline understands the trust is not facing a staff shortage, and does not have many employees self-isolating after catching or being exposed to Covid-19.
Exeter's MP Ben Bradshaw said the move was 'very good news for patients' and would 'take the pressure off the Royal Devon and Exeter Hospitals and other local NHS services to cope with unprecedented Covid-19 pressures'.
The Labour MP added it was 'something I raised with Matt Hancock two weeks ago'.
Speaking virtually in the Commons he told the Health Secretary on November 10 his local NHS wanted to use the hospital, but did not have the staff to do so.
'What exactly is the purpose of the Nightingale hospitals when there are not the doctors and nurses to staff them?,' he said.
The Nightingale hospital in Exeter was hastily put together in a former Homebase store during the first wave of the pandemic.
There have been mounting concerns over whether the hospitals, quickly built at an estimated cost of £220million to the taxpayer, are value for money.
