Intertec: Passively-Cooled Shelters for Remote Equipment in Hot and Arid Climates
| By Intertec
The reliability of electronics equipment is dramatically shortened if it operates in very hot conditions, which is why much electronic equipment incorporates fan cooling. Equipment builders designing for arid climates have always faced considerable environmental protection problems. Traditional cooling techniques require a power supply, which often poses severe difficulties. The problem is growing bigger as the topology of SCADA evolves towards more distributed and unmanned systems, and new solutions are being sought. Although solar cells and DC powered air conditioning techniques are making progress, their relative lack of efficiency, together with the problems of battery lifecycles in hot climates, continues to make environmental protection complicated and expensive.

BlueCielo - Improving Operational Efficiency at RWE
| By BlueCielo ECM Solutions
With almost 60,000 employees supplying energy to over 16 million electricity customers and 7 million gas customers, RWE AG is one of the leading power generation companies in Europe. The company produces energy by regular and brown power stations, as well as nuclear and regenerative power plants. RWE continually works on methods to improve and optimize the efficiency of its new and existing power stations. Optimization is a key aspect in the engineering, design and construction of new and existing power stations. Efficiency is an important factor in the planning of the operations and maintenance of the power stations.

PLEXOS Study of the Italian Power System and Market in the Medium-Term: Realities and Expectations of Renewables Integration
| By Energy Exemplar
One of the main developments of the last few years on the Italian power market has been the significant increase of renewable capacity in the form of wind and solar power plants. Using a PLEXOS dataset based on data available from Terna and various utilities, we have modeled the Italian power market considering the six geographical zones and created the medium term expected scenarios from the Terna information available for 2012 and the published 2013 grid development plan.

Adjustable Speed Pumped-Storage Hydro-Generator (PSH) Evaluation by PLEXOS
| By Energy Exemplar
Energy Exemplar is engaged in this project sponsored by the Department of Energy through Argonne National Laboratory to perform the power system operation simulation to evaluate the fixed-speed pumped-storage hydro-generators (FS PSH) and the adjustable-speed pumped-storage hydro-generators (AS PSH) in the areas of: quantifying the value of the FS and AS PSHs under different market conditions and for different levels of variable renewable generation (wind and solar) in the system; and providing information about the full range of benefits and value of PSH and CH plants and recommendations for appropriate business models for future PSH projects.

North of Delta Off-Stream Storage (NODOS) Project Benefits Study
| By Energy Exemplar
The economic viability study of the proposed North-of-Delta Off-Stream storage (NODOS) pump storage project was originally completed by the United States Bureau of Reclamation (USBR) and the California Department of Water Resources (CDWR) in early 2013. This document summarizes an update to that study performed for USBR, by Energy Exemplar (EE) and Pinnacle Consulting (Pinnacle), consulting firms specializing in the evaluation of power generation assets in California and in the Western Electricity Coordinating Council (WECC) system, which includes the provinces of Alberta and British Columbia, the northern portion of Baja California, Mexico, and all or portions of 14 Western states in the United States including California.

Evaluation of the Impact of Including Start Costs in SEM 2020 Wind-Integration Scenarios
| By Energy Exemplar
Base load thermal unit start costs include energy (fuel and CO2) and non-energy (wear and tear, extra O&M) components. Most wind integration studies have ignored non-energy components. This research examines the effect of including non-energy start costs on scheduling.

Irish and British Historical Electricity Prices and Implications for the Future
| By Energy Exemplar
This paper compares retail and wholesale electricity prices in SEM, the market of Ireland, and BETTA in Great Britain. Estimated wholesale costs are much lower in BETTA. We show that this is mostly because the wholesale price in BETTA is set too low to cover generation costs, although it is compensated by large retail margins. The substantial need for new investment in generation in Great Britain suggests that returns to generators will have to increase. Developing a market mechanism to compensate generators fairly while simultaneously reducing retail revenue will help in achieving this goal.

An Assessment of the Impact of Irish Electric Vehicles Target on 2020 Wholesale Electricity Prices
| By Energy Exemplar
The Irish Government has set a target that 10% of all vehicles in its transport fleet are to be powered by electricity by 2020 as part of its strategy to deliver the 10% RES-T target. This paper investigates what impacts on the power system and electricity market in Ireland the electrification of 10% of the transport fleet will have.

Reduced Network Modeling of WECC as a Market Design Prototype
| By Energy Exemplar
California’s administration, legislature, and energy regulators have adopted aggressive targets for renewable energy, which will result in profound changes in markets and system operations as the resource portfolio shifts from heavy reliance on natural gas as a fuel for electric generation to intermittent, often remote resources. As part of determining workable modeling approaches as changes in market design are considered, this paper examines the necessary level of detail for modeling unit commitment.

Recognition of Extended Dispatch Horizons in California’s Energy Markets
| By Energy Exemplar
Effective in 2009, the California ISO launched a new market structure that combines advanced unit commitment and dispatch processes with recognition of physical characteristics of the transmission system and generation resources. California’s upcoming implementation of aggressive targets for renewable energy will result in new, profound changes in markets and system operations. The CAISO is responding by making additional improvements in its unit commitment processes.

Power System Optimization by Increased Flexibility
| By Energy Exemplar
Great amounts of renewable energy are installed into power systems at state, regional and national level, often due to fulfill legislated mandates or renewable portfolio standards (RPS). While renewable energy is a means for reducing reliance on fossil fuels and decreasing greenhouse gas emissions, it is increasingly evident that there is need for flexible thermal fleet to help balance the renewables. The primary fuel considered for new builds is natural gas, and the default technology to meet capacity and flexibility needs is gas turbines in simple or combined cycle. In this work we show the substantial system benefits of increased flexibility and improved dynamic dispatch capability. This is achieved by exchanging traditional gas turbine based plants in the planning process to gas-fired combustion engine plants.

Forcasting the Long-Term Emissions Intensity Factor for Electricity Markets: An Australian Case Study
| By Energy Exemplar
Improvements in emissions intensity via technological innovation will enable the pathway to reductions in greenhouse gas emissions, which in turn will enhance our chances of avoiding significant changes in the environment. To avoid massive structural changes to our economy and societal dislocation due to a significantly more variable and an even hostile climate, a methodological framework for establishing the true emissions intensity of electricity production is required.
