I have been reading a bit about Demand Response and Energy Efficiency. Utilities both public and investor owned are trying to implement joint programs for energy efficiency and demand response. Few pertinent questions come to my mind.
What does this sync up mean for the end users.. commercial and large industrial end users of electricity and what does this partnership provide the utilities? What are the resources and services available in the market for businesses to analyze and implement such a program?
EE and DR are kinds of demand side energy management techniques. EE is permanent while DR is temporary based on time, season, price and load conditions on the grid. Utilities benefit from EE as they are able to reduce their base load. Energy efficiency is a kind of permanent demand side energy management slightly different from temporary load based demand response. Utilities need both kinds of demand side energy management . They embrace EE for long term load curtailment and DR for active load management.
As for the business customer of the utility, demand response until now was an option which the Facilities/Operations/ Management decided to participate in or opt out under various kinds of programs offered by the utility. However, the stage is being set for automated demand response (ADR), due to the communication upgrade by the utility in terms of smart meter and automated servers (the whole AMI infrastructure). If utility’s infrastructure becomes capable of sending price signals to the business customer via smart meter/server in near real time, demand response gets a higher value and attention as a demand side management tool. This is because of real time based pricing instead of negotiated flat rate, DR has the capability to provide potential monetization for the customer.
The big question is are businesses ready for that kind of scenario. Based on my experience, very few commercial/ industrial customers have the tools, resources or management approval for DR, leave aside ADR. DR impacts business operations and reliability in most energy intensive enterprises. Hence it has always been an item with pending decision.
What are the resources available for large business customers to analyze and explore the combination of EE and DR. EE is being implemented in almost all companies where the ROI is less than one year. In addition where incentives and subsidies bring ROI to a palatable level such as solar, the projects get funded. Most utilities provide DR programs. If the in-house demand side management resources are tight and a company needs outside help in analyzing and managing DR there is help in the marketplace.
Based on my research I have found consulting and DR service providers who offer help in understanding all the variables in EE/DR/ADR . Some firms are pure consulting firms that help the companies understand the energy market holistically from supply and demand side and optimize an energy strategy for them, which includes EE/DR planning and implementation. Such as KEMA (http://www.kema.com/services/consulting/utility-future/smart-grid/demand-response-market.aspx), Navigant Consulting (http://www.navigantconsulting.com/industries/energy/energy_efficiency/) and many more. Typically you would also need in house resources for implementation. There are others that operate as pure DR providers. They are regional or national aggregators who work with end users, utilities and RTO/ISO’s to solve the problem of oversized demand. Companies such as CPower http://www.cpowered.com/about.php; EnerNOC http://www.enernoc.com/index.php; Ziphany http://www.ziphany.com/drp.html; Eisenbach Consulting http://www.eisenbachconsulting.com/demand-response.php .
Below are few details on offerings from different providers.
EnerNOC: offers both DR and EE. EE uses Monitoring based commissioning for uncovering savings. They monitor all the systems of the building after integrating the systems with their central control panel. Based on monitoring and analysis they offer EE opportunities.
Ziphany: offers mainly DR along-with meter data management platform. They do not provide integration service with building systems and equipment such as EnerNOC.
Eisenbach Consulting: offers mainly DR along-with energy procurement services.
CPower: offers both DR and EE. However, the target market for EE is Utilities and not business owners.
I am not advocating any provider over the other. I am sure there are more DR providers that provide load management solutions and consulting firms that can help companies analyze their business needs and align the energy strategy with the company’s goals. My aim to let the business managers, operation managers know that if DR is getting ignored due to other priorities they can seek help. The best way to address EE and DR is to define a comprehensive energy strategy for the company- both from the supply and demand side. If the supply side is the constant, then they can focus their resources on demand side management. Defining overall strategy should be the first goal and action plans & resource allocation should be developed later. This is crucial since in the future companies will have to factor in cost of carbon in their energy strategy from procurement to end use.
This article is not intended as a technical resource but my attempt at defining the constraints, barriers for widespread adoption of demand response by end users. Hope you enjoy reading.
