RWE is supposedly looking to invest in solar power plants, citing solar module prices as one of its key determining factors. According to Bloomberg, up until now Germany’s second-biggest utility, which owns a stake in Spain’s Andasol 3 solar thermal power plant, has distanced itself from investing in PV generation because of what it considered too high of a cost for the technology. However, now that prices for solar modules are considerably lower than in the past, the utility is taking a second look.
