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.
(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.
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.
Election politics portend painful cutbacks.
Whether it deserves it or not, the solar energy industry can’t count on continued government largess, thanks in part to the Solyndra mess. But in the end, Solyndra’s demise might be exactly what the industry needs to wean itself off heavy subsidies and become a mainstream resource.

DC monitoring raises the bar for solar power plants
As solar generation systems grow in number and size, they will pose new challenges to the electric grid. Integrating solar energy calls for applying sophisticated monitoring and synchronization technology, to allow operators to keep track of operating parameters and ensure as much solar electricity as possible can be integrated into the grid.
