Late last week, smart grid member companies from the Research Triangle Cleantech Cluster (RTCC) met with U.S. Rep. Renee Ellmers (R-NC-02) to discuss a comprehensive energy approach that supports domestic production of both renewable and fossil fuel resources to help the country achieve energy independence.
Virtual power plants (VPP)--which combine independent resources into a network via sophisticated planning, scheduling, and bidding of DER-based services, bringing distributed generation (DG) and demand response (DR) together to provide a synergistic sharing of grid resources-- are expected to play an increasingly important role in the future of the power sector, according to Navigant Research.
After an exhaustive review, the U.S. Department of Energy (DOE) has issued a Presidential Permit for the Champlain Hudson Power Express-- a buried transmission line that will connect New York City and Quebec. A Presidential Permit is required for the construction, operation, maintenance and connection of electric transmission facilities at the international borders of the United States.
International energy investment company, Continental Energy Corporation, has announced that its Tanzanian affiliate, Ruaha River Power Company Ltd., has begun construction on the first of four of its Malolo Mini-Grids. The project has a long list of subscribers, as well as a waiting list of at least 400 who are beginning to be subscribed.
HVDC allows power transmission through cables over longer distances and higher capacities compared to AC transmission, but the immature nature of offshore HVDC technologies can cause uncertainties and increased risk exposure for stakeholders and can make projects complicated and costly.
The Court of Appeals for the District of Columbia Circuit recently upheld the Federal Energy Regulatory Commission's (FERC) Order No. 1000, which requires public utility electric transmission providers to engage in regional transmission planning and cost allocation. South Carolina Public Service Authority v. FERC, No. 12-1232 (August 15, 2014). The decision means that both public utilities and non-public utilities (chiefly rural electric cooperatives and governmental entities), which are not subject to the full jurisdiction of FERC, will have to work together to a greater extent to plan, build and pay for transmission facilities.
Collaborating with a group of science and technology partners, including Argonne National Laboratory, Illinois Institute of Technology, and the University of Denver, ComEd is taking a lead role in positioning interconnected microgrids as viable energy systems that help address ongoing challenges of national energy security, sustainability, and resiliency, as well as positioning Chicago as a hub for energy sustainability and independence.
When one coal-fired power plant is replaced by renewable energy sources like solar and wind, what are the implications for grid stability and blackout restoration? What happens if you replace two? As utilities move toward integration of more renewable energy sources, they face difficult challenges in determining the right mix and placement of critical assets to maintain grid stability.
Despite several challenges, Kenya, Tanzania and Uganda have a transmission and distribution (T&D) industry filled with potential, and is an industry ripe for investment, according to Frost & Sullivan.
Most nations are experiencing a similar, significant increase in the integration of distributed generation and a corresponding decrease in costs, despite different generation mixes and distribution system structures, according to a Global Smart Grid Federation (GSGF) study on grid connectivity.
