What's Solar Really Worth?

Requests for proposals to supply solar power facilities frequently specify prices to be stated in only one way—dollars per watt DC, or dollars per kilowatt-hour, for example. But a one-dimensional approach to pricing leads to skewed valuation, because different technologies and system designs produce value in different ways.

As the competition for commercial and utility scale photovoltaic (PV) projects increases, a better method for comparing proposal prices is needed to accurately value each offer. Currently, a common practice is to evaluate projects on a dollar-per-watt ($/W) basis, either DC or AC. This assumption is only valid as long as all the proposals have their DC or AC system sizes the same.

Frequency Regulation

In a recent order, the Federal Energy Regulatory Commission (FERC) said that by paying the wrong price for the ancillary service known as frequency “regulation,” system operators have encouraged too many gas-fired turbines and other conventional fossil power plants to supply regulation service.

Putting market economics ahead of reliability, the Federal Energy Regulatory Commission (FERC) has told regional transmission organizations (RTOs) and other grid system operators (ISOs) to rethink the prices they pay for the ancillary service known as frequency “regulation.”

In short, FERC wants all power plants to do what they do best — recognizing that some may be well adapted to providing regulation service, but others perhaps not.

Vendor Neutral

(December 2011) Lafayette Utilities System selects Elster’s EnergyAxis as its AMI system; ABB wins contract from Hydro-Quebec; Sapphire Power Holdings acquires gas-fired power generation from Morris Energy Group; Consumers Energy awards contract to Babcock & Wilcox; plus announcements and contracts involving BP Wind Energy, Abengoa Solar, Samsung C&T and others.

Fostering Smart Grid Evolution

A deliberate approach to infrastructure advancement.

The electric power system has been getting smarter for decades, as new technologies allow better analysis and greater control. But most utilities have implemented these technologies in a piecemeal way, rather than as part of a long-term, enterprise-scale strategy. What are the consequences of this fragmented and incidental approach, and what would happen if we developed the smart grid in a deliberate way instead?

Electric Vehicles and Gas-Fired Power

A strategic approach to mitigating rate increases and greenhouse gas price risk.

Experience in the Duke Energy Carolinas service territory shows that high penetration rates for electric vehicles, combined with increased natural gas-fired power generation, can result in lower costs to customers and lower risks for utility shareholders—while also reducing total emissions of greenhouse gases. However, these outcomes depend on policy changes that facilitate smart, off-peak vehicle charging, and that allow utilities to capture the benefits of a more environmentally friendly power system.

Trusting Capacity Markets

Does the lack of long-term pricing undermine the financing of new power plants?

The PJM Interconnect’s Reliability Pricing Model generally has succeeded in attracting and retaining low-cost generation and demand resources to maintain resource adequacy. But sluggish demand and low prices have weakened the market for long-term capacity contracts. Suppliers aren’t willing to lock in current low prices, and buyers don’t want to pay more for future certainty. Is the market dysfunctional, as some state lawmakers suggest, or does the lack of long-term contracts indicate a rational balance of supply and demand?

Turnkey Redefined

Engineering and construction firms adapt to a changing market.

Engineering, procurement and construction (EPC) contracts are evolving as utilities seek to spread risks, contain costs, and execute their business strategies. As a result, turnkey contractors are adapting their capabilities to meet the industry’s changing needs. Leading EPC firms share their vision for a 21st century energy industry—and their role in building it.

Open Access on Trial

The old rules don’t always fit with new commercial realities.

To encourage billions of dollars of investment into America’s transmission grid over the next several decades, the Federal Energy Regulatory Commission (FERC) is restructuring its regulatory policies to bring market-based solutions into the framework for planning, construction, and operation of new transmission lines. The recent Order 1000 is the most dramatic example of this effort. But as FERC has learned before, one set of rules doesn’t serve the financial and commercial needs of all market participants.

Capacity Value Trap

Are merchant power assets overpriced?

By some measures, merchant power assets look like a bargain, selling for well below their replacement cost. But whether low prices signal a buying opportunity or a value trap depends on the outlook for electricity demand growth—not just in the long term, but also in the fairly immediate future.

Transactions (December 2011)

Riverstone/Carlyle acquire eight power plants; Entergy pays $346 million to NextEra for Rhode Island plant; plus asset sales by First Energy and Thermo Cogen, and debt issues by MarkWest, Atlantic Power, Mississippi Power, and SCE totaling $1.6 billion.
