Challenges for the Implementation of Renewable Energies:

Experiences from China and Germany

To successfully establish renewable energyinfrastructures you have to address four issues…

System Integration

Administrative / Regulatory

Skills & Qualification

Technical




Creating an efficient mechanism is the mainadministrative challenge


Goal:

•Efficient mechanism topromote generation fromrenewable energy sources

It is about KWh generated andnot KW installed

Easy to implement and

monitor

Give the right incentives for asustainable development of thesector (no boom & bust cycle)

System Integration



Technical




Policy priorities are changing over time

Inception

• Clear renewableenergy strategyand targets

• Attractive support

• Set up regulatorysupport

time

d e p l o y m e n t Early takeoff

• Predictableincentives

• Focus on non-economic barriers,e.g. transactioncosts, permits,

• Manage total

support costs

Advanced takeoff

• Predictable andrapidly adaptableincentives

• Manage totalsupport costs

• Focus on systemintegration

Consolidation

• Focus ontransformation ofthe energy

system

• Create a marketto expose RE tocompetition

• Secure publicacceptance

Based on IEA Study: “Deploying Renewable Energy”

Decrease the Feed In Tariff / Output Incentive over time

Incentive Based Regulation

: Principle: Decoupling ofrevenue from costs

Incentive: Grid operators maygenerate higher profits if theyrelease efficiency reserves andreduce costs.

Efficiency gains are initiallydelayed, but passed on to thecustomer permanently.

For extensions and restructuringmeasures it is possible to file forinvestment budgets




Main technical issues are availability and cost of energy

Technical

Goal:

•Have the appropriatetechnology, which has

the best levelizedcost

of energy in place

• Ensure Availability

Data source: ISET, IWET 10/2010

Germany used a public database to increase the knowledgeabout failures in wind turbines

Broad data baseimproves

conditions for windfarm operators



Develop a system to maximize feed in and grid stability

System Integration

Goal:

•Ensure grid stability

•Maximising feed-in of partlyvolatile renewable energysources

•Ensuring quick grid access

System Integration

Administrative


Technical



In Germany grid expansion remains a major challenge

Situation in Germany

Successful integration of renewable energyrequires new transmission lines

Federal Network Agency (BNetzA) manages

the process 480 applications for investment budgets

have been made, with a total volume ofEUR 15 billion

A big part has already been approved

24 priority projects have been identifiedand attributes priority in a special law(“EnLAG”) – but: delays expected

Most projects got green-light by BNetzA

Delays mostly due to planning law

China is working intensively on how to better integrate windpower to the grid and addresses the challenges

Fossil power dominates generation in three-North regions Almost no oil or gas based generation This leads to a insufficient power balancing capability

Power system balancing challenges increase



China is updating its development plan for a provincial,regional and national power system including wind power



Qualification matters, especially for renewable energies


Goal:

•Have enough qualifiedpersonnel to support thegrowth of RE installationsSystem Integration

Administrative


Technical



The wind power boom in China is a challenge for skills andqualifications

Demand projection for O&M staff for China in 2020



Tools and curricula for qualifying employees for tasks in thewind sector are available

EU project from 2006 to 2009 See: www.windskill.eu

Summary

Large scale deployment of Renewable Energy installations isnothing less than thebeginning of the transformation of the energy system

To get large scale deployment in RE started...

» Financial incentives and investors confidence in stableframework conditions are key prerequisites

To develop large scale deployment in RE sustainably...

» Implementation is key»Sustainable implementation needs a whole „ecosystem“

including skills, technical know how and practical know

how to do



Thank you for your attention!

Volatile feed-in results in pricefluctuations on the wholesalemarkets

Smart meters enableconsumers to respond theprice fluctuations, e.g.

recharge the batteries oftheir electric cars

run appliances at acheaper rate

Use of these methods must befinancially attractive
