How to deal with new technology being introduced in the power system

Peter Vaessen

One of the challenges in transmission and distribution is the safe and reliable introduction of new technology in the power system. As a key performance indicator of the grid is reliability, you can imagine that ideally only “proven” technology should be introduced.

This is where the challenge comes in: How do you de-risk new technology? Potential and proven solutions are testing in the laboratory and piloting in the field. Notice that this cannot be done for big and expensive technology solutions, e.g., the development of offshore substations that are needed to connect remote offshore wind farms to the grid on land. A typical ballpark figure for a large offshore substation, able to connect in the order of 800MW wind power, is in the range of 1-2 billion USD. Continue reading

KETRACO & DNV GL: Transmitting the future to Kenya

Sliman Abu Amara

Earlier this year DNV GL announced it had been contracted to advise on the construction of a 400kV high voltage overhead transmission line and substations in Kenya. The Kenya Electricity Transmission Company Limited (KETRACO) selected us as part of the country’s Kenya Vision 2030 development programme.

As a member of the team working on the project, I wanted to outline the reasons behind the initiative, and why we felt best placed to bid for this work.

Energy efficiency as a first resource among equals

Thomas Ledyard

The notion of energy efficiency as a resource on equal footing with conventional generation has long been a goal of the efficiency industry. Until recently, establishing a means to commoditize efficiency sufficiently to compete in generation planning has proven to be an elusive goal. In 2008, a Forward Capacity Market (FCM) began operating and evolving under the auspices of the Independent System Operator of New England (ISO-NE). Through this marketplace, ISO-NE auctions off electric demand savings at peak demand periods to offset anticipated future capacity needs, including retirement of power plants.[1] Continue reading

Are US utilities ready for the deployment of energy storage?

Ali Nourai

Are utilities convinced that energy storage is an effective solution for a specific real problem or a specific opportunity in the energy market?

I recently revisited the Distributed Energy Storage Roadmap Survey DNV GL conducted on behalf of The National Alliance for Advanced Technology Batteries (“NAATBatt”), and found myself wondering how utilities think about storage in general, and what they think about the effectiveness of distributed storage in functioning as a much larger storage unit.

CIP Version 5 won’t affect my company, right?

David Carty

You’re a registered entity with a small compliance staff. It’s a new year and time to conduct another RBAM (risk-based assessment) of your facilities. It’s okay, though. You’ve never had any critical cyber assets under Versions 3 or 4 and, therefore, never had to look past CIP-003; plus, there have been no major equipment changes. Who cares if CIP Version 5 comes and goes? It will be business as usual, won’t it?

This may be the thought process running through the minds of registered entities who haven’t kept pace with Version 5 or the new CIP standards. Well, guess what? The new standards are here and people are starting to lose sleep. The standards have effective dates as early as February 2014 with initial enforcement scheduled for April 2016. So stop, take a deep breath, and ask yourself: What’s really changed that could affect my situation? Continue reading

DNV GL helps the Middle East tackle energy trilemma challenges

Mohammed Atif

View this blog post in Arabic.

A recent article published by the International Energy Agency summarized some interesting statistics with respect to Saudi Arabia’s power sector needs. The article cited annual growth in demand at 7.5%, which if served by domestic resources would result in the power sector consuming 8.3 million bbl/day of crude oil by 2028. The article also discussed potential solutions being considered in Saudi Arabia, such as the plan to install 41 GW of solar power capacity by 2032 based on both photovoltaic (PV) and concentrated solar power (CSP) technology.

لخصت مقالة حديثة نشرتْها وكالة الطاقة الدولية بعضًا من الإحصائيات المثيرة للاهتمام والتي تتعلق باحتياجات قطاع الطاقة في المملكة العربية السعودية. وقد ذكرت المقالة أن حجم النمو السنوي المطلوب يبلغ 7,5%، والذي إذا ما تم إتاحته بالموارد المحلية-  فسوف يتسبب في استهلاك قطاع الطاقة لحوالي 8,3 مليون برميل يوميًا من النفط الخام بحلول عام 2028. وتناقش المقالة كذلك الحلول المحتملة التي يتم النظر فيها في المملكة العربية السعودية، مثل خطة لتثبيت 41 جيجا وات من قدرة الطاقة الشمسية بحلول عام 2032 بناءً على كل من تقنيتيْ الطاقة الكهروضوئية (PV) والطاقة الشمسية المركزة (CSP).

Meeting Frequency Response Requirements (BAL-003-1)

Raymond Gilby

NERC’s Frequency Response and Frequency Bias Setting standard (BAL-003-1) has an enforcement date of April 1, 2015. During this implementation period, a number of Balancing Authorities (BA) have used NERC’s FRS Form 1 to determine where they are relative to the requirements. The form is populated with 2013 frequency events and BA specific information calculated from the previous year’s FERC-714 filing. The BA can then populate with Interchange and load data using FRS Form 2. The results of Form 1 are transferred to Form 2, which compares the BA’s Frequency Responsive Objective (FRO) with the Frequency Responsive Measurement (FRM) for each event. Continue reading

Energy efficiency planning – Going global, working locally

Luisa Freeman

“Countries that use energy more efficiently use fewer resources to achieve the same goals, thus reducing costs, preserving valuable natural resources, and gaining a competitive edge over other countries.” This statement introduces the American Council for an Energy Efficiency Economy’s (ACEEE) 2014 International Energy Efficiency Scorecard report, where Germany, Italy, the EU, China and France head the list of the world’s 16 largest economies included in the analysis. The countries included in the annual survey represent around 80% of global GDP and about 70% of global electricity consumption. But recent years have seen many other countries and regions of the world start to explore and capitalize on their energy efficiency opportunities as well. Continue reading
