Cap-Ex Conundrum

Does slow and steady still win the race?

When a capital-intensive industry enters an asset-building cycle, many companies will operate in the red for a few years or more. That’s not necessarily a bad thing, as cap-ex investments represent growth for shareholders. The devil is in the details, however, and companies facing a large slug of environmental compliance investments might produce disappointing returns over the next few years.

Gas Demand Response

As more natural gas is used for power generation, more volatility can be expected in gas markets. Demand response might provide a tool for managing that volatility, but is it technically feasible? And will gas customers accept it?

In general, demand response refers to the ability of consumers to respond to a supply shortage by curtailing demand, thereby improving economic efficiency. Since the California energy crisis, demand response has been widely used in electricity markets throughout the United States and Canada.1 Recent developments in the natural gas sector suggest that the time may have come to also introduce demand response in that sector.

EVs and the Smart Grid

Better batteries, renewables and more intelligent electricity networks are converging to deliver efficiency and environmental improvements. Electric vehicle (EV) batteries are both the stumbling block and the catalyst for transformative change.

A century or so ago, Thomas Edison’s commercialization of electricity unleashed an unprecedented cascade of change, altering the way humanity worked, lived and interacted. Today, with the convergent rise of the smart grid, renewable energy and electric vehicles (EVs), the power sector is embarking on a second era of transformation that promises to deliver a smarter, greener and more efficient 21st century.

Better Safe Than Compliant

Protecting the smart grid requires a broader strategy.

NERC’s critical infrastructure protection (CIP) standards set a minimum level of security performance—and only for high-voltage transmission systems, not the distribution grid. A compliance-checklist approach to security might lack the adaptability needed to combat evolving threats like the Stuxnet worm. A multi-layered, risk-based approach will provide better protection for the emerging smart grid.

Securing Tomorrow's Grid (Part II)

Public-private collaboration to protect our infrastructure.

Smart grid technologies bring a host of cyber security considerations that need to be addressed throughout the transmission and distribution domain—and even into the customer’s home. In the second of two exclusive articles, Department of Energy authors team up with industry experts to provide a path forward for securing the smart grid.

Planning for Efficiency

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.

Grid 2050

Shaping system transformation.

New technologies—and new expectations—require taking a fresh look at the institutions and practices that have provided reliable electricity for the past century. Collective action is needed to define the key attributes of a future grid and then to take the more difficult next step—adapting our processes and institutions to align with that future vision. A thoughtful approach will allow America to capture the potential value that’s offered by sweeping changes in technologies and policies.

The NOPR Was Late

But transmission planning, as we know it, may never be the same.

The recent landmark ruling on transmission planning cost allocation, known as “Order 1000,” and issued by the U.S. Federal Energy Regulatory Commission in late July 2011, could well produce an unintended side effect — the formation of regional compacts among states to identify needs and plan for development of new power plant projects.
