Spectrum of Holistic Energy Solutions

• Incorporation of customer load modification as alternatives or additions to traditional resource planning

• Intervention by utility on the “customer side of the meter” to change magnitude or shape of customer loads

• Broad range of alternatives for reducing, adding or changing load

• Partnership between customer and utility with benefits to both

• Usually involves actions by utility on the customer side of the meter

DSM enables to view generation,

transmission, distribution and consumption as

part of integrated system to

maximize benefits

Different market drivers

DSM Target Sectors

• Identification of DSM potential• Development of individual DSM

programs• Cost benefit analysis,• M&V protocols, • Regulatory Mechanism• Detailing institutional

requirements

DSM Service

SOP – DSM as energy resource!!

A Standard Offer programme uses EE as resources for the benefit of Utilities and implementation of EE. Consistent with DSM regulatory framework

Utility to purchase EE on long term contracts at a pre-determined value based on savings of KWh

Utility procures power reduced by the amount it has contracted through energy savings

AT&C losses get reduced due to energy savings

Targeting equipments that influence peak power could reduce power purchase cost.

Alternatively, in deficit markets, energy savings allows better supply to industrial and commercial customers and get higher revenues

Consumer save significant energy and benefitted from reduced energy bill.
