to ramp up and down.
Grid operators increasingly rely on loads to participate in the management of the electric grid.

The Challenge for LoadsIt is hard for loads to participate directly in most ancillary services markets– Responsiveness required is quite frequent, often bi-directional– The reality is that the load’s primary objective outweighs participation in
challenging markets
Additional administrative challenges – Understanding the markets– Bidding requirements; real time monitoring; measurement and verification– Managing real time changes in availability and status
Almost certainly requires some form of aggregation to help coordinate the response of many loads to deliver the robustness, reliability and resiliency required by the power system --- DER’s

RegulatoryFERC Order 719 Requires ISO’s to create a level playing field in ancillary services markets– Largely, they can (and do) claim to have done this
In reality, most jurisdictions continue to have “technical, administrative” barriers to entry– Do not permit loads to aggregate to provide ancillary services– Aggregation rules are somewhat arbitrary and slow adoption– Operational systems (at ISO’s) not upgraded for different resources to
participate; reluctance to establish as priority– Do not allow multiple CSP’s to participate with same clients (creating
effective barrier to new entrants)– Layered rules: States require separate registrations

Drive and Focus of ISO’s and UtilitiesLargely, ancillary services markets are functioning reasonably well (almost completely served by generation side assets)In most ISO’s, other priorities, driven by larger stakeholders, dominate the agenda
Almost everyone believes that loads can provide ancillary services, and most think it is a “good thing”– But most are not focused on seeing more of it happen
Requires stronger support among policy makers – Minimum targets for demand side participation?– Encouragement in load participation?– Fortitude to understand and make

Engagement of LoadsRecession of 2008 took the pressure off -- reduced scrutiny over energy bills– Reduced demand caused a reduction (generally) in electricity prices– Also reduced volatility in prices– Reduced corporate pressures to reduce energy costs
Some (legitimate) concern over implications of participation in ancillary services markets– Requires more “connectness”– Requires new thinking and some effort (implies early adopters first)– Not sure whether it is “worth it”
Most markets for ancillary services have experienced price declines– Less value -- certainly a concern for loads to participate – Less assured return -- participation in a market does not produce a guaranteed
return– Different than traditional DR

Making it HappenUtilities can provide the necessary leadershipRun commercialization programs .. – Small pilots don’t encourage real participation– Large, real loads want to know there is a long term program that will pay them for
their participation– Their time -- to evaluate and implement -- is available ... They don’t like to waste
itInsist on real results that truly have the capability for broad roll-out– Any and all pilots should have this characteristic– They should be economic and viable ...
Use the brand and leadership of the utility to encourage and value load participation– Loads do look to the utility to understand “what is important”– When they see it, they act!
