Least Cost Pathway for Power Sector Investments for the states of Gujarat, Karnataka, Maharashtra and Rajasthan through 2030

Between 2015 and 2021, India’s renewable energy capacity more than doubled from 40 GW to 100 GW, supplying nearly 10% of the total electricity generated in the fiscal year 2021. India has a target of 500 GW of non-fossil fuel capacity by 2030. With increasing renewable energy penetration, it is important to analyse optimal flexibility requirements to ensure grid stability and reliability. In this context and in collaboration with Lawrence Berkeley National Laboratory (LBNL), Idam Infra has conducted a study to analyse Least Cost Pathway for Power Sector Investments for four states namely Gujarat, Karnataka, Maharashtra, and Rajasthan.

Using PLEXOS – an industry-leading energy modelling software – Idam has analysed optimal fuel mix for the four states and identified optimal and least-cost pathways for meeting 2030 requirements. Our studies find that these four states can meet ~36% or 181 GW of India’s non-fossil fuel commitment of 500 GWs by 2030. Further, no new thermal capacity addition may be necessary. Adequate storage (pump storage and/or battery) and other flexible resources like load shift will help maintain grid stability and reliability even during high stress periods.

The reports for the four states are as follows:



Guidebooks for Demand Aggregation and Utility Led Business Models

The role of Distribution Utilities in promoting and harnessing rooftop solar potential cannot be emphasized more. However, there has been a slow progress on this count, particularly in deployment of residential rooftops across state utilities in India.

In this context, Idam Infrastructure Advisory Private Limitedin association with KPMG Advisory Services Private Limited has developed two knowledge products as a part of Asian Development Bank (ADB) supported Technical Assistance programme namely, (a) Guidebook for Demand Aggregation (b) Guidebook for Utility Led Business Models for facilitating Solar Rooftop Investment in India. These guidebooks show how India plans to meet its ambitious Rooftop Solar energy targets and why identifying new business models, better engaging utilities and developing new market mechanism will speed up its adoption.

(a) Guidebook for Demand Aggregation: It explains how factors such as access to finance and policy uncertainty are slowing the roll out, and how demand aggregation can help utilities lower costs, reduce risk and expand market opportunities. This guidebook describes the approaches to program design and implementation and list the important parameters that any utility should consider before designing a demand aggregation program. The guidebook is published in ADB’s website:

Guidebook for Demand Aggregation

(b) Guidebook for Utility Led Business Models: It explains India’s renewable energy targets and explains why rooftop solar generation has been slow to increase despite an enabling policy environment and attractive economics. The utility can play an active role and drive the adoption of rooftop solar through development and implementation of new and innovative business models. This guidebook identifies the roles and responsibilities of various stakeholders and discusses four business models to help utilities evaluate and finetune their strategies. It shows why taking a targeted approach can maximize economic benefits for utilities and deliver long term advantages for consumers. The guidebook is published in ADB’s website:

Report on ‘Acting on Climate Change: The Time is Now

Green Artha and Ashoka undertook a study on ‘Acting on Climate Change: The Time is Now’. The study focused on identifying and showcasing diverse, innovative large-scale ideas and systems-change approaches that accelerate the adoption of collaborative action.

Balawant Joshi, MD, suggested a way to incentivize funding for banks. He stated, ‘there is a need for carbon offsets/carbon financing solutions to underwrite the new risk models for banks. Currently, they ask for a high level of collateral even for a 25 Lakh loan which is obviously not viable for MSMEs.’ His insights are quoted in the section “Creative and Collaborative Climate Finance”, pg. 43-44.

Transmission Reform Agenda and Action Plan for India

The transmission business is a natural monopoly and must be regulated to ensure fair access and prices for users, efficient and reliable operation and to encourage optimal investments. A strong and robust transmission system is key to reducing the overall cost of power and enhancing system reliability. This assumes even more importance in light of the inevitable transition to integrating high shares of renewable.

Along with strong regulatory oversight, effective Planning, Pricing and Participation models will be the key elements within the transmission sector reforms. The note focuses on the potential solutions to address the challenges around optimal transmission capacity planning and additions and will thereby enable investment for faster development of transmission infrastructure in India. It has evolved through extensive deliberations and consultations with a Transmission Expert Group and captures priorities of the reform agenda and suggests potential actionable interventions.

Idam Infrastructure Advisory Private Limited. with the support from Prayas (Energy Group) and Shakti Sustainable Energy Foundation has authored report on ‘Transmission Reform Agenda and Action Plan for India’.

Repowering of Old Wind Turbines in India

Idam Infra’s study report on “Repowering of Old Wind Turbines in India”, was launched at the Indo-German Energy Day event held on 18 September at REI Expo 2018, India Expo Mart, Greater Noida. This study event was funded by the Indo-German Energy Forum (IGEF).

The Government of India’s renewable energy (RE) target of 175 gigawatt (GW) has led to an unprecedented capacity addition in the recent years. In the case of wind energy, the Government has not only set a target of 60 GW, but has also initiated competitive bidding resulting in significant decrease in the cost of energy. Owing to this initiative, presently, India has successfully achieved 71 GW of RE capacity as on 30 June 2018. For effective utilisation of wind resources, it is necessary to utilise wind potential at these sites. Thus, replacement of old wind turbines or ‘repowering’ assumes importance. Therefore, the Government of India announced the “Policy for Repowering of Wind Power Projects” on 05 August, 2016. However, despite the Policy, actual uptake of repowering project is rather slow. An up-to-date and revised study on the “Repowering of Old Wind Turbines in India”, commissioned by IGEF/GIZ and prepared by Idam Infra analyses the market for repowering in India, reviews the existing policies both for central and state governments and provides an overview of international success stories.

This revised and updated report shall re-ignite the debate on the challenges faced by repowering projects leading towards potential solutions.

Policy Brief RGGVY DDG Scheme Guidelines, With Emerging Economy

As India, with emerging economy, continues to develop rapidly, resulting in rapidly increasing demand surpassing massive capacity additions by government over decades. Improving access to modern energy sources, such as electricity, remains a key development challenge for the country and can play a critical role in improving social and economic well being of the rural population. With this very intention, in 2001/02, the Government of India pledged to provide ‘electricity for all by 2012’—a target later extended to 2017. To meet the target, two key ministries of the central government, namely the Ministry of Power (MoP) and the Ministry of New and Renewable Energy (MNRE), launched several programmes including flagship national programme for rural electrification, namely RGGVY, the Rajiv Gandhi Grameen Vidyutikaran Yojana, launched in 2005. Although RGGVY had managed to extend grid infrastructure to most of the census villages by the end of the 11th Five-Year Plan (2007-2012), adequate and reliable power supply remains a distant dream. In 2009, to provide electricity to villages and hamlets that are beyond the reach of the conventional grid, MoP launched the Decentralized Distributed Generation (DDG) Scheme as part of RGGVY. Despite intense effort more than 275 projects could get sanctioned and less than dozen, mostly SPV based small projects in Andhra Pradesh, could get commissioned toward fag end of 11th Plan. In this context, “Climate Change and Development (CCD) Division”, Embassy of Switzerland through its “Village Electrification through Sustainable Use of Renewable Energy (VE-SuRE)” engaged Idam Infra Team, for undertaking policy and regulatory analysis to identify the reasons because of which the developers are not coming forward to invest in DDG projects and also to suggest suitable modifications in the DDG guidelines to resolve the problems faced by the developers. This policy brief presents the findings of a study that sought to answer the question and offers a solution in the form of suitable modifications to the guidelines drawn up by the DDG scheme-modifications that, it is hoped, will attract developers from the private sector.
