Factoring customer-owned generation into forecasting, planning, and operations.

The long-predicted future of distributed generation is now becoming a reality. Customers increasingly are installing and operating behind-the-meter generation systems, creating challenges and opportunities for utilities. ConEdison’s experience demonstrates the dangers and challenges, as well as the opportunities for becoming partners with utility customers.

As new energy efficiency programs proliferate, regulators increasingly will seek to use the associated demand reductions to reduce capital expenditures on new transmission and distribution assets. However, forecasting the expected geographic distribution of these demand reductions within the grid and integrating this information into a utility’s capital planning process is a challenging task.
Preparing the grid for large-scale renewables.
With large solar arrays and wind farms being proposed to connect to transmission and sub-transmission systems, are utility companies sufficiently prepared to handle the challenge of integrating these large intermittent resources? The industry now must decide whether transmission reliability factors — most notably dynamic voltage support and system frequency management — need to be resolved by renewable generators, or whether they should become a cost of doing business for transmission providers and reliability coordinators.
Integrating distributed resources into the smart grid.
The remedy for America’s gravest economic woes may lie in a smart grid that can deliver vast amounts of clean, renewable energy while enhancing our energy security and democratizing our energy system. Although regulatory questions and technical challenges might dominate the industry’s short-term focus, the smart grid’s driving forces parallel America’s long-term national interests — a fact that should guide ongoing technology strategies and investment decisions.
Smart solutions for distributed renewables.
The goal of implementing a distribution management system (DMS) is to upgrade isolated, hands-on grid management processes into an interconnected and automated platform. This technology is transforming the way utilities operate distribution networks, and setting the industry on a path toward seamless integration of distributed resources—both supply and demand.
Past accomplishments and future plans.
Policy makers in the E.U. and the United States are taking different approaches to facilitating smart grid development. While both regions are setting standards that the rest of the world likely will follow, they also face difficult challenges in resolving issues around cost recovery, customer engagement and workforce preparedness.
Bringing flexibility and efficiency to energy RFPs.
Joseph Cavicchi and Andrew Lemon
With the introduction of retail competition in the electricity industry, regulatory authorities in many jurisdictions are now overseeing the purchase of electricity at wholesale by electric utilities for customers that do not otherwise obtain supply from independent retailers. There are two primary ways in which, under the supervision of regulatory authorities, electric utilities purchase electricity for these non-shopping customers: through simultaneous descending clock auctions or through fairly common sealed-bid auctions, commonly known as Requests for Proposals.
Effective metrics give solar its due credit.
Photovoltaic (PV) power generation is an intermittent, non-dispatchable resource generally considered as energy-only with no capacity credit. However, there is ample evidence that solar energy reliably is available at peak demand time when loads are driven by day-time commercial air conditioning, and can contribute effectively to increasing the capacity available on a regional grid.
Fundamental changes require bold strategies.
While many utilities have embarked upon efforts to define a path toward the next generation utility, these efforts often are siloed initiatives driven by the generation, transmission and distribution (T&D) or customer segments of the organization. Addressing the upcoming challenge will require a coordinated and integrated set of decisions so as not to sub-optimize the end-to-end value chain. Eight critical themes across the generation, T&D and customer elements of the value chain will shape the future of our industry.
Is DER competitive with traditional utility investments, and if so, what are the costs and benefits?
Eugene L. Shlatz & Steven Tobias
Utilities must make hard tradeoffs regarding which distribution investments offer the greatest value. How should they quantify DER as integrated into the grid?
