제목 : Renewables Integration in India

발췌내용 : This report suggests ways for India to maximise the amount and value of solar and wind power in its electricity system. It addresses demand-side flexibility, power plant flexibility, storage (pumped-storage hydro and batteries) and grid flexibility, as well as policy, market and regulatory solutions for the short to medium term. It adds to existing research by focusing on renewable integration in individual states, rather than at the national level, as the power system flexibility challenges, solutions and priorities are different in each state. The report presents findings from consultations with national and regional stakeholders and the results of parallel in-depth analysis, including two newly developed, detailed power sector production cost models developed at the IEA to illustrate flexibility challenges and solutions specific to the India context – the five-region India Regional Power System Model and the Gujarat State Power System Model.

[목차]

I.       Executive summary

A.     India’s energy demand is growing rapidly

B.     High renewables increasingly challenge the power system

C.    Indian states should leverage all potential sources of power system flexibility to maximize the value of solar and wind

D.    Policy and tariff reforms can tap into demand response potential

E.     Rooftop solar systems need to be monitored and managed

F.     New regulatory and policy frameworks can activate more flexibility from storage and power plants

G.    Inter-state trading still faces barriers; changes to wholesale markets and power purchase agreements can remove key barriers

H.    Flexibility reduces curtailment, and lower curtailment means reduced system operating costs and lower CO₂ emissions

II.     India’s clean electricity path

A.     Historical progress towards India’s ambition to integrate 450 GW of renewables by 2030

B.     Variable renewables become dominant across all major pathways

C.    Integrating renewables in India will require action at both the central and state level

D.    India’s states are at the forefront of RE integration globally

E.     The global IEA framework for understanding renewables integration challenges

F.     Power sector modelling provides system-specific insights

III.    Renewables integration challenges

A.     India’s states face many local RE integration challenges

B.     How high shares of solar and wind challenge the status quo

C.    Flexibility lowers curtailment, and lower curtailment comes with reduced system operating costs and lower CO₂ emissions

A.     Power system flexibility now and in 2030

B.     Demand-side flexibility becomes a top priority

C.    Power plant flexibility remains a largely untapped potential for states today

D.    Batteries and pumped storage hydro can improve system flexibility but regulatory framework is missing

E.     System strength and inertia may need attention in some states before 2030

F.     Inter-state trading still faces technical and economic barriers

V.     Policy recommendations

A.     Curtailment
