The gallery also paid £84,709 for two pieces by Argentine artist Victor Grippo. Energy Of A Potato is a potato connected to an electric meter with wires while Tables of Work And Reflection consists of seven wooden tables inscribed in chalk and marker pen with lights hanging over them.
It has previously published a total figure, but was criticised by the Charities Commission earlier this year when it bought a piece from controversial artist Chris Ofili for an ' undisclosed amount' when he was a trustee.
It spent £600,000 on The Upper Room, an installation by Ofili partly made with elephant dung. The incident sparked a storm over artisttrusteesbenefiting from the sale of their work to the gallery.
A Charity Commission inquiry concluded the Tate's 'conflict of interest policies' were not in line with established good practice. The full list disclosed yesterday will do little to restore its credibility over what it spends its money on.
Charles Thomson, a co-founder of the Stuckists, who promote traditional art, said: 'Now we know why the Tate has been so reluctant to tell anyone how they're spending our money.'
David Lee, editor of The Jackdaw, a leading art magazine, added: 'What interests me is that they claimed to be broke. They're constantly moaning about having no money and yet they've been able to buy 500 works - when 80 per cent of the collection is not on display but in store.'
Unveiling its annual report today, Tate Britain said it had a record 1.7 million visitors in 2005. Tate Modern saw a drop in visitors to 3.9million in 2005 from 4.4million in 2004 - but is still the most successful modern art museum in the world.
