* Gold rises as oil firms, dollar holds ground
* Middle East gold buying picks up as prices slip from highs
(Adds comment, updates prices)
LONDON, June 18 (Reuters) - Platinum and palladium prices rose on Wednesday as traders fretted over the outlook for supply from South Africa, while gold ticked up as oil edged higher and the dollar firmed against the euro.
Platinum climbed 2.5 percent and palladium reached a three-month high as a South African official warned the country could face a severe energy crisis, and after state power utility Eskom said it would lift electricity prices. [
]South Africa's public enterprises minister Alex Erwin said on Wednesday the country could "face a very, very severe energy crisis in one to two years' time" if Eskom failed to raise funds in the capital markets.
Spot platinum <XPT=> rose to $2,095.00/2,105.00 an ounce from $2,052.00/2,072.00 late in New York, having earlier touched a session high of $2,103.50.
Spot palladium <XPD=> rose to $460.50/468.50 an ounce from $456.50/464.50, after reaching a high of $468.50, its firmest level since March 19.
The metals had already been firmly underpinned by supply issues linked to South Africa's power problems and the prospect of a miners' strike next month.
"When you have 75 percent of the world's platinum produced in one country and you have power problems there, that is going to be explosive in terms of price action," said BNP Paribas analyst David Thurtell.
The republic also produces a third of the world's palladium and 11 percent of gold mine supply.
"South Africa is the world's number two gold producer," added Thurtell. "When you have rising energy costs and problems with supply, that will have an impact on prices."
Earlier on Wednesday, Eskom received regulatory approval to raise its electricity tariffs by an additional 13.3 percent year-on-year for 2008/2009.
The tariff increase amounts to a 27.5 percent average raise year-on-year, the regulator said. A rise in power costs is likely to hit all mining activity in the republic.
"We expect the power shortages in South Africa to hit output of gold, platinum and base metals quite badly," said Commerzbank analysts in a note.
"Global production of platinum metals in particular is likely to suffer severely, as most platinum is mined in South Africa," they added.
Meanwhile gold edged higher as oil prices ticked up and as the dollar firmed a touch against the euro.
Gold <XAU=> was trading at $887.40/888.40 an ounce at 1403 GMT from $884.20/885.40 late in New York on Tuesday.
The precious metal is struggling to find direction as the market debates the next move for the dollar. Gold typically moves in the opposite direction to the dollar, as it is bought as a hedge against weakness in the currency.
However, demand indicators are positive.
The world's largest gold exchange traded fund, StreetTRACKS Gold Shares, said it saw a 2 percent or 12.27 tonne inflow on Tuesday, bringing its total holdings to 617.48 tonnes, their highest level since April 22.
Gold ETFs issue securities backed by physical stocks of the precious metal which can be traded on exchanges, allowing investors to gain exposure to metals prices without holding the metal itself.
A rise in ETF holdings has represented a key source of demand for gold since the launch of the first precious metals ETF in Australia in 2003.
There are also signs that Middle Eastern jewellery demand may be picking up, with Dubai gold sales for May rising 18 percent from the previous month as easing prices brought buyers back to the market. [
