FRANKFURT (Reuters) - German utilities are likely to partner with automakers to tap into a 1 billion euro (748.11 million dollar) government incentive scheme for electric cars, an RWE (DE:RWEG) executive said.
Driven by fear that energy will be dominated by the likes of Google (O:GOOGL) and Apple (O:AAPL), both of which have made forays into the sector, power firms are focussing on vehicle-to-grid communication as a possible source of revenue.
"We assume there will be partnerships between utilities and carmakers in the near future," Thomas Birr, head of strategy at RWE, Germany's second-biggest utility, told Reuters.
This could involve integrating electric cars into the grid and using their power to satisfy peak demand or to store surplus energy, a market expected to grow to $7.5 billion by 2020.
Earlier this month Nissan (T:7201) said it was launching a trial this year with Italy's Enel (MI:ENEI) to allow electric car owners in Britain to sell electricity back to the National Grid (LON:NG) and potentially make money in the process.
While there has been little uptake for electric cars in Germany so far, a government support programme announced last month raised hopes that demand will improve and drive the need for infrastructure, including charging stations.
RWE, which is in the process of pooling its renewable, grid and service units into an entity separate from its loss-making power plant business, has already installed more than 3,100 such stations, more than half of Germany's roughly 5,800.
But rather than just focussing on building more, RWE is looking at how it can earn money by integrating the rising number of electric vehicles into the power grid, which already needs to cope with a major surplus in renewable energy output.
"What you don't want is the power grid to collapse if there happen to be three electric cars charging in the same street at the same time," Birr said.
Utilities say that selling power alone will not be enough to keep them going in the future and are banking instead on their expertise in managing power grids at a time when Germany's energy supply becomes more decentralised.
