1. Future Challenges For Metropolises
rural areas investments mainly driven by DG
metropolises high customer density and structural complexity
electric vehicles / storage facilities
demand side management / energy efficiency
integration of DG (photovoltaic and CHP)
smart potential; no direct push today
Sandra Maeding – Germany – Session 6 – 0931

2. Investment Needs Example Berlin
relevant is the impact on specific areas (not on average)
extended grid monitoring including the low voltage level
integration of electric vehicles and intelligent charging
integration of DG and reinforcement of the grid
demand side management for SME und Prosumer
reach the optimum of investments needed
Sandra Maeding – Germany – Session 6 – 0931

3. Disincentives Of The Current Regulation
Vattenfall Distribution grid: 300 Mio. € capital cost under absorption
Characteristics of Regulation
CAPEX-time-shift reduces achievable RoR to ~ 4 %
reductions due to benchmarking
missing technical standards
unclear roles / responsibilities
CAPEX covered by approved revenues
Real CAPEX
Sandra Maeding – Germany – Session 6 – 0931

4. Recommendations investments: compensation of the CAPEX time shift
planning cost approach
yearly adjustment of capital cost based on book values
planning reliability for Smart Metering
clear roles and responsibilities
minimum standards
implementation of innovations-incentives
projects fostering Smart Grids should be recognized
pilots and R&D cost should not be part of the benchmarking
