Bmwi Study Expansion Of Distribution Grids May Cost Eur 23 To 49 Billion

Bmwi Study Expansion Of Distribution Grids May Cost Eur 23 To 49 Billion
In organize of the German Energiewende that aims to mushroom the group of renewables of 23.4% in 2013 to 80% in 2050, the Central Ministry for Financial Interaction and Vigor (BMWi) has vacant a appraisal on the need for swelling and retrofitting of the sector grids to which 90% of all renewable power plants are interrelated. The appraisal quantifies the need for swelling using three option scenarios and points out and assesses ways to hand out blame by using experienced get technologies and inventive understanding and practicing strategies.

1. SCENARIOS AND Cut

The appraisal has assessed the contract for the adherent three scenarios

A. "EEG 2014 Diagnosis

The action reflects the goals of the council laid imbibe in the in the nick of time sort-out of the Renewable Vigor Sources Act (EEG 2014), working with the finish of an installed world power of renewable power that director than doubles from shortly 61 GW to 128 GW by 2032 (60 GW wind power, 59 GW solar power, 9 GW other renewable sources). Cut for get swelling and renovation in this action would extent to faultily EUR 23 billion, the authors say.

B. Diagnosis B "NEP"

The spare renewable swelling action reflects the assumptions of the action "B", which the movement get operators used for their get development plan for 2013. Out cold this action the installed world power of the German renewable power plants would spring to 139 GW (65 GW of wind and solar power and 9 GW provided by other renewables). This would command to contract for the grids of EUR 28 billion by 2032, according to the appraisal.

C. Diagnosis "L"ander"

This action reflects renewable monstrosity based on the policy by the sixteen German states (L"ander). Installed world power would spring to 206 GW by 2032 (111 GW wind power, 85 GW solar power and 10 GW provided by other renewable sources). Cut for get modernisation would mushroom to EUR 49 billion, the appraisal estimates.

D. Assumptions And Product

80% of the investment is pleasing in the inside and high-voltage grids, the appraisal says. It moving parts from the finish that for get swelling on the great voltage arrange hush-hush power cables preference be used, bookkeeping for on the order of two-thirds of the get contract on the high-voltage arrange and on the order of one third of the downright swelling contract.

In downright 130,000 km of new power cables preference own to be laid by 2032 less the EEG 2014 action and 280,000 less the "L"ander" action. Cut for the sector grids preference spring by 10 % to 20 % over and done with the subsequently 20 lifetime, with 70% of the contract arising over and done with the subsequently 10 lifetime.

The need for investment varies depending on the piece and the voltage arrange. In southern Germany present-day preference be a suspicious need to invest in the low-voltage grids due to persistent solar monstrosity, though 39% each 33% of the investments in high-voltage grids are caused by wind power in northern Germany and eastern Germany. On the medium-voltage arrange the need for swelling is director or not more than absolutely drawn-out.

Newborn understanding combination with experienced technologies reduces the need for swelling more willingly the appraisal finds. This applies in suspicious to a generation or input pronounce (Erzeugungsmanagement). According to the appraisal the need for get swelling would lessening by 30% if get operators were not be bounded by to hand over for keep a tight rein on input, but were legitimate to leading edge input by wind and solar power plants by 1% annually. Annual report contract for the reconciling of renewables may perhaps correspondingly be discounted by at least 15%, the authors charge. They tell to suitable the lawmaking provisions accordingly. Chief reactive power or significance pronounce would by match up to drop the need for get modernisation record scarcely the appraisal says, time convenient native plant transformers (Ortsnetztransformer - rONT) would command to a lessening of the need for get swelling in the low voltage arrange and drop annual report contract by 10%. A mixture of generation pronounce and convenient native plant transformers would steady command to a hit of the annual report contract by 20%. In addition it would anesthetize imbibe the confined redouble relating the get contract. Instant, inventive understanding would command to falling massive contract, they repeatedly caused upper practicing contract, this was not reflected in the extant dogmatic grid. Accordingly it had to be amended to set sincere incentives, the appraisal says. The make a difference for the proceeds caps for get operators had to confiscate popular understanding that the need for get swelling differed regionally, in suspicious almost neatness factors.

2. BDEW Type Network Reconsider

In Tramp 2011 the Central Organization of the Vigor and Pond Sweat (BDEW) had vacant a appraisal on the need for the swelling of the German sector networks and the contract ther in organize of the reconciling of the right and proper new PV and wind power world power until 2020.

A ultimate tariff say may perhaps not be through as the council used two different sets of data, BDEW thought at the incident. One the one hand, the government's Vigor Inkling proposed with an installed world power of 33.3 GW in 2020. If one took this say as a basis, whichever 195,000 km of power ramparts for sector networks had to be built at a tariff of up to EUR 13 billion. In its 2010 excerpt action (BMU-Leitszenario), the Central Ecology Ministry (BMU), so far, had hypothetical additional wind power and PV world power of 51.8 GW. Based on this say, whichever 380,000 km of new sector lattice power ramparts were pleasing, resulting in contract of up to EUR 27 billion, BDEW thought in 2011.
