Presentation Title:  Journey to Cost Effective Modernization at Priest Rapids

Presentation Date:  Thursday, July 16, 2015

Presentation Time:  2:30 PM – 4:00 PM

Session 5H4: Technical Papers; Modernization and Life Extension

The lessons learned and cost-saving solutions applied on the Priest Rapids modernization project provide valuable insights to clients with an aging hydropower fleet.

Abstract:

Equipment upgrade demands a review and study of several factors that influence a plant modernization strategy and drive the decision process to reach a desired vision. Whether that vision is only equipment life extension while maintaining the output parameters or increasing unit output at the same time, the common goal is reaching a cost effective solution that satisfies  the stakeholders and is technically sound.  In most of the cases, a key decision in the modernization process is deciding whether to reuse a specific component or structure that has been in operation for decades. The modernization of Priest Rapids generators did not divert from this approach. After several months of studies, which included reverse engineering and detailed FEA modeling of the original and modified generator stator frames under different loading scenarios, engineers at MWH found a clear path that will define the possible reuse of the stator frame. The study to be presented by the authors of this article will show the journey MWH engineers went through when undertaking the assignment and the different considerations and assumptions made to successfully complete the study. The study will be accompanied by a variety of model output results under different working conditions, stator frame stress maps and the sensitivity checks and validation process that was following made during the course of the study.

Title:  The 84-MW New Bong Escape Hydropower Project – First Privately Developed Hydropower Facility in Pakistan – Challenges and Solutions

Presentation Date:  July 15, 2015

Presentation Time:   9:30 AM – 11:30 AM

Session PG-W22:  Poster Gallery

The success of the first privately-developed hydropower facility in Pakistan has sparked a wave of private hydropower development in that electricity-starved country, with global implications. 

Abstract:

The 84-MW New Bong Escape Hydropower (NBE HP) Project is the first privately-developed hydropower facility in the history of Pakistan.  Its successful completion on 23 March 2013 has paved the way for a rapidly-expanding role of the private sector in the development of Pakistan’s hydropower potential, leading to plans for new development totaling over 8,000 MW. At the HydroVision 2010 conference in Charlotte, MWH made a presentation regarding this pioneering project, for which final design and construction were just getting under way at that time.  The NBE HP Project is owned by private developer Laraib Energy Ltd., a subsidiary of Pakistan’s first thermal Independent Power Producer, the Hub Power Company (Hubco). A joint venture of MWH and Pakistani Engineering firm NESPAK is the Owner’s Engineer. The current presentation provides a brief history of the project, some of the challenges that were encountered in executing the work, and how these challenges were met in order to achieve a successful project outcome.

Presentation Title:  Modeling of Additional Operational Capabilities and Valuation of Benefits Provided by Adjustable Speed Pumped Storage Technologies

Presentation Date:  July 15, 2015

Presentation Time:   9:30 AM – 11:30 AM

Session 1H4:  Flexibility of Pumped Storage for Grid Reliability

Learn about the latest computer modelling tools and results obtained to better understand technical, economic and financial performance of pumped storage projects.

Abstract:

This paper presents the analytical approach and key results of a recent study funded by the U.S. Department of Energy’s Water Power Program. The study sought to enhance the modeling and simulation of advanced pumped storage hydropower (PSH) technologies and examine the value of different services and the contributions that they can make to a power system. The technical approach consisted of two main components: (1) advanced technology modeling and (2) detailed production cost and revenue simulations.

The advanced technology modeling focused on the development of dynamic simulation models of the advanced PSH technologies, such as the adjustable-speed and ternary units. These new models were developed as vendor-neutral models and published during the course of the project.

The power system simulations focused on the Western Interconnection (WI). The analyses were performed for the entire WI, for the California electricity market, and for a single balancing authority — BANC (Balancing Authority of Northern California). The goal of the study was to provide a comprehensive evaluation of PSH plants and their contributions to the power system. The project team used several computer tools, including the PSS®E, FESTIV, CHEERS, and PLEXOS models, to simulate power system operations and the contributions of PSH plants. The operations of fixed and adjustable-speed PSH technologies were modeled in both regulated and competitive market environments. Depending on the modeling tool, the times of the simulation steps ranged from a fraction of a second (dynamic system simulations) to one hour (annual production cost simulations). This paper presents an overview of the simulations applied to the valuation of benefits of adjustable-speed PSH technologies and some key results of the analyses.

Presentation Title:  Innovative Fish Passage Facilities Added to Soda Springs Dam Enable Generation to be Maximized at Seven Upstream Hydropower Peaking Plants

Presentation Date:  July 15, 2015

Presentation Time:   1:30 PM – 3:30 PM

Session 2J3:  Fish Passage and Protection: the Northwest Experience

The innovation practices applied at Soda Springs Dam help expand the potential solutions for adding volitional fish passage while maintaining operational function of existing dams around the world. 

Abstract:

PacifiCorp Energy’s Soda Springs Hydroelectric facility on the North Umpqua River in Oregon consists of an arch dam and power plant that regulate flow from seven hydroelectric facilities.  Upstream and downstream fish passage at Soda Springs Dam was undertaken as part of PacifiCorp’s new FERC license.  Soda Springs Dam is a 309 foot long, 77 foot high concrete arch dam including a 72 foot long, gated, concrete ogee spillway section.  Fish passage improvements included a fish screen for 1,600 cubic feet per second (cfs), a fish ladder, and spillway modifications to increase downstream fish survival during spill periods.

PacifiCorp selected a preferred configuration within one spillway bay.  The radial gate was removed and the spillway crest was lowered approximately 16 feet to accommodate the new 170 foot long fish screen structure on the left bank of the river.  Up to 1,600 cfs of screened flow is carried in a 12 foot diameter steel flowline that free-spans the river and connects to the original flowline. Another 275 cfs of screened fish attraction flow passes through an energy dissipation valve to the fish ladder entrance constructed at the base of the dam. Water from the reservoir passes through the intake to new fish screens while juvenile fish from the reservoir continue past the screens to a traveling weir.  The juvenile fish and 30 cfs pass over the weir into a pressurized steel pipe that transports the fish downstream to an evaluation facility where they can be examined and/or passed directly back to the river.

A half Ice Harbor fish ladder provides volitional upstream fish passage starting at the base of the dam. The fish ladder is tunneled for 100 feet under a spillway extension.  To accommodate the 14 feet of reservoir fluctuation, the exit pools in the fish ladder have automatic gates that control the ladder inflow and allow fish to swim into the reservoir at all operating levels. The gates operate incrementally based on the reservoir elevation.

Fish have been using the facility since fall 2012. The new facilities open several miles of previously blocked habitat to anadromous salmonids, lamprey and other aquatic species.

Presentation Title: Hydroelectric Pumped Storage Potential and Renewable Energy Integration in the Northwest

Presentation Date: July 15, 2015

Presentation Time: 9:30 AM – 11:30 AM

Session 1H3:  Flexibility of Pumped Storage for Grid Reliability

The industry has huge potential to grow by tapping into the need for grid stability as more and more utilities increase their renewable energy portfolios.  

Abstract:

Wind generation on Bonneville Power Administration’s (BPA) system in the Northwest grew from almost nothing in 1998 to more than 4,515 megawatts in 2014. The majority of this existing and future potential wind resource is located in the Columbia River Gorge.  BPA’s integration of wind is the highest amount as a percentage of load of any utility in the country.

With the clean energy goals of the region and the carbon emissions reductions from the EPA’s proposed Clean Power Plan Section 111(d), the Northwest is facing the retirement of over 3,000-MW of coal-fired generation, further exacerbating the need for dispatchable energy assets.

Wind energy is one of the most affordable forms of electricity today to meet these clean energy and carbon reduction goals. However, the challenges and Achilles’ heel of wind integration lie in the intra-hour variability and uncertainty of wind, making wind energy a difficult resource to dispatch.

The challenge is to find a way to make energy created by intermittent resources like wind and solar energy available on demand to meet current and future load growth. BPA experiences large, unplanned ramping events that occur within the hour and days from several hundred to several thousand megawatts. These large ramps, up and down many times, do not align with when energy is needed by residential and industrial customers.

Hydroelectric pumped storage is a superior solution that offers maximum flexibility to store energy produced on BPA’s system from wind or other renewable resources when it is difficult to utilize these resources on the power grid or integrate them into the power system and to release the energy at a time when it is needed, most often during peak load periods, at a higher value.

Additionally, the present transmission congestion, under or oversupply and overload could be reduced by having a pumped storage project located near significant high-voltage transmission to take advantage of Northwest and Southwest geographic diversity of loads and output from renewable resources, inter-regional exchanges and to mitigate the steep ramping needs, California’s “duck curve,” overgeneration risk and economic de-optimization of the power system.
