Energy and peak deficit in Tamil Nadu

Energy Peak

Total installed capacity – 18 GW

Capacity of renewable energy installations – 7.5 GW

Few of Restriction and Control (R&C) measures implemented in Tamil Nadu are:

• 40% base demand and energy cut for HT industries and commercial consumers

• Introduction of power holiday to all HT, LT-CT, and LT industries for one day between Monday and Saturday on staggered basis

• All HT industries have to declare Sunday as weekly holiday

• HT industrial and commercial consumers are restricted to draw more than 10% power from grid for lighting and security purposes during evening peak hours, etc.

Strategy to bridge electricity deficit

Bridging electricity

deficit

Supply side management

Demand side management

Supply Side Management:

• Capacity addition has long gestation period

• Improving efficiency of existing generatingstations

• Procurement from other states

Demand Side Management:

• Relatively smaller gestation period

• Managing end-use demand

• Benefits for the distribution utility by reducingthe short-term power purchases at high rates

Managing end-use demand

Reduction in demand

On-site generation

from RE resources

Strategy for managing end-use demand

Reduction of demand:

• Investing in energy efficiency equipments

On-site generation from RE resources:

• Investing in on-site generation installationsbased on RE resources

Identification of cluster (Industrial & Commercial)

Techno economic analysis of selected options

Development of institutional arrangements for implementation of DSM programme

Identification & selection of potential RE based DSM options

Feasibility analysis of implementation of RE based DSM programme

Developing bankable Detailed Project Report (DPR) for RE enabled DSM options

Development of off-grid implementation

roadmap for replication of RE DSM in TN

11 June 2013

• Tirupur cluster selected• 10 industrial and 10 commercial units were visited

Identification of cluster (Industrial & Commercial)

• Resource availability is good - solar irradiation and biomass

• RE technologies – Solar PV, Solar Thermal, Biomass gasifier

Identification & selection of potential RE enabled DSM

options

• Replacement potential: Tirupur – 56 MW, 14 clusters – 352 MW

• Equity IRR (without subsidy): Solar (13-15%), Biomass (45%)

• Equity IRR (with MNRE subsidy): Solar (18-20%)

Techno-economic analysis of selected options

56 MW replacement potential estimated in Tirupur cluster

11 June 2013

• Aimed at HT industrial, HT commercial consumers, manufacturers of Solar PV, thermal systems, biomass gasifier and TANGEDCO officials

• Dissemination of findings of techno-economic analysis of RE enabled DSM options

• Enrolling industries and commercial consumers that are interested in developing bankable DPRs

Awareness workshop at Tirupur cluster

• Collection of basic data for DPR completed in 8 industrial units• Preparation of bankable DPR in progress for evince financing• Assist in Procurement process and enabling commercial roll-out

Developing bankable DPRsfor industrial and commercial units

• Review of similar off-grid initiatives in Southern states of India• Encashing learnings and experiences of developing bankable

DPRs• Devising off-grid implementation roadmap for taking RE

enabled DSM forward in TN• Suggesting institutional arrangements for implementation

Development of off-grid implementation roadmap

Harnessing replacement potential

Section 4Benefits to TANGEDCO

11


11 June 2013

• TANGEDCO will get following benefits due to implementation of this innovative RE enabled DSM implementation:

• Relief to grid due to shifting of demand to load centre

• Reduced power purchase during peak time resulting in lowering of expense on power procurement

• Associated reduction in emissions

Benefits to TANGEDCO

Section 5 – Synergy between state DSM Policy and off-grid implementation roadmap


State DSM Policy• Suitable institution will be

constituted and mandated to perform activities related to DSM including RE enabled DSM

• Ensure provisioning for performance incentives for achievement of DSM targets

Off-grid implementation roadmap

• Assist the utility in achieving its DSM targets

• Establish coordination between the industries and commercial consumers with the constituted institution
