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

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.
