The Swiss authorities launched measures to hurry up the allowing and development of alpine PV within the Alps in October. A brand new incentive scheme for these installations is about to be introduced in April. pv journal spoke with Lionel Block, renewable power venture supervisor at Swiss engineering agency Planair, concerning the new provisions.
Switzerland made modifications to the Vitality Act in October 2022, specializing in pressing measures to make sure electrical energy provide in winter. The brand new Federal Regulation goals to create and speed up the development of enormous PV programs put in on land within the Swiss Alps, 1,500 meters or increased above sea degree.
Particulars of the regulation have thus far been scarce. Earlier than the official publication anticipated in April this 12 months, pv journal spoke to co-author of the IEA-PVPS Activity 1 report on PV functions in Switzerland, Lionel Block, concerning the modifications to come back.
“The concept is to essentially deal with PV manufacturing in winter as a result of in Switzerland now we have a greater system yield (kWh / kWp) within the mountains than at low altitudes, the place there’s a excessive focus of clouds, ” the renewable power venture supervisor of the Swiss engineering agency Planair stated pv journal.
The measures are imagined to incentivize alpine PV tasks with an annual power manufacturing of a minimum of 10 GWh, equal to an put in capability of a minimum of 8 MW, based on Block.
The Swiss authorities will subsidize as much as 60% of the set up prices of eligible tasks. “This consists of prices for cabling, which will be very costly with alpine PV,” Block stated. “The prices for these alpine tasks are round CHF 6 ($6.47) / W, in comparison with CHF 1.2 / W for city installations. With these very excessive subsidies, it may possibly nonetheless be worthwhile for to the proprietor.”
To qualify for the subsidy, tasks should exhibit a winter yield of a minimum of 500 kWh/kWp, which is barely attainable in alpine circumstances, based on Block. To fulfill this requirement, builders will probably deal with vertical PV installations and reap the benefits of the upper albedo of bifacial modules, added the engineer.
Winter yields are more likely to be measured in three years, based on Block. “There’s a danger concerned for the venture homeowners as a result of if the harvest situation shouldn’t be met, the subsidy is not going to be paid – however the regulation may also be modified,” he added.
The Swiss authorities goals to succeed in 2 TWh of alpine PV manufacturing utilizing the inducement scheme.
In September, the Swiss power firm Axpo commissioned a 2.2 MW vertical alpine PV venture at Muttsee Dam, nearly 2,500 meters above sea degree. It’s stated to be the most important alpine photo voltaic plant in Switzerland.
