Wind Turbines and Bird Fatalities

"Last month, biologists found 484 bird carcasses at the AES-owned Laurel Mountain wind installation in West Virginia. The mass mortality event did not involve turbines."

"...(apparently the) cause was that migrating birds were drawn to lights left on at the facility’s electrical substation in cold foggy weather. The birds, it is theorized, were galvanized and disoriented by the bright lights and circled until they died and fell out of the sky."

This article also provides an interesting chart on bird mortalities and the various causes.

Grid Connectivity Talk Hosted by Greencape Initiative (Cape Town)

We attended a "Grid Connectivity" talk hosted by the Greencape Initiative in the Cape Town CBD today. Our rough notes on what was covered are given below[for confirmation of the facts, refer to the Greencape Initiative website]:

FIRST, OUR COMMENTS:
It is interesting to note that at events such as this, it has become apparent that there is substantial public interest in smaller projects and home installations. The fact that getting net metering off the ground could be difficult due to the potential risk of loss of income to Municipalities is unfortunate and makes one wonder about the actual purpose of these public bodies (i.e. protecting the public's best interests v being a going concern as if a private company). We do, however, hope that the steps Eskom is taking to allow for IPPs to get RE projects off the ground in SA are going to be fruitful and we think that the Greencape Initiative is a valuable support structure to help this process get off the ground.

OUR ROUGH NOTES:
The main speaker was Riaan Smit, Chief Engineer of Network Planning at Eskom.

Riaan started by reviewing the outcome of the first bidding process for SA's tender for the procurement of renewable energy by Independant Power Producers for which applications were accepted up to 04 November 2011.

149 applications for wind power projects, 122 Solar PV, 9 CSP & 41 applications for 'other' projects were received. Wind was clearly proved the most popular (in terms of the number of applications submitted) with PV following close behind.

In terms of capacity (MW), wind power again came tops, taking roughly 75%.

Rebid progress (started 17 November 2011):
Only 53 bids have been confirmed as received.
Many applications are not meeting the necessary requirements (environmental and other)
[Note: preferred bidders to be announced by the DoE over Cop17 (Durban).]

THE GRID & DIFFERENT RENEWABLE ENERGY TECHNOLOGIES

Challenge:
Where to develop new grid. Lead times of projects etc. New grids need to be built over the next 30 years.

Different technologies - Impact on the grid:
wind - You get the older and newer concepts all with different specs in terms of: power regulation; speed; gearbox; type; inverter, and voltage. There is a need to model the various types (a, b, c and d). Types C & D favoured (DFIG & PMSG[full power electronic converters]).
Ref: africa electricity.com

CSP - discussed two types of energy storage:
steam storage vessel (e.g. Spain example) or salt storage.
Indicated that steam storage "stabilised production during cloud transient - more grid friendly".

TECHNICAL CONCERNS / AWARENESS

1.thermal loading of lines and transformers
2.voltage variations during the normal operation
3. overvoltage studies for RE projects
4. voltage recovery after faults
5. phasing out old networks [instead of fixing existing infrastructure, maybe redo on new network.

(dependant on size and location)

Took Laingsberg wind power facility as an example - expect high voltages; small voltage changes due to line outages.
power factor control characteristic - need to choose correct wind turbine technology [C or d].

Line lengths are a big factor - Longer the line, increase in losses, voltage changes, limit transfer, capacity constrained.

what to do? Thicken[?] up conductor? Ask developers to move sites?

More technical concerns/awareness:
6.reactive power control
7.focus on load modelling
8.short circuit currents. fault level.
9.limit system losses vs maximum use of thermal capacities
10.reliability required by wind, pv, csp, other developers.
11.impact on power quality aspects.
12.transmission system requirements such as voltage stability
13.dynamic studies for various technologies, including mw networks.
14.impact on sub-synchronous resonance for cape network (rotor movement in cape v rotor movement north - can cause resonance).
15.voltage sags due to breaker operation
16.cable/transformer inrush currents
17.influence on ripple control systems.

CURRENT ESKOM ACTIVITIES:
Staff went to Denmark to visit two facilities for 3 weeks to gain practical experience. Feedback is that we are not as far behind as what was anticipatied. The main focus during this visit was skills development and new documentation.

Grid access unit established - customer service interface and applications.

Distribution master plans and network development plans to cater for RE scenarios. What to expect? Which applications will be approved? How to plan for networks in future.

Distribution self build policy and guideline - expect for it to be available Dec 2011.

Transmission updating generation connection capacity assessment future scenarios - A follow up of GCCA-2012. Making some changes to this. Should be available middle next year (scenerious up to 2040) [IRP going on to 2013]. Will build different scenarios, including less nuclear scenario to see if replaced by RE how it will be.

STILL NEED TO ADDRESS requirements for small renewable energy projects (based on NRS 097-2). Smaller i.e. 1mw and bigger.

Nothing yet for smaller than 1MW. Commented that maybe get the bigger ones goings and then tackle 100kw (household). Maybe next year. NRS 097-2 - making provision for smaller project technical requirements.

Smart grid working group.
people say smart grid(s) are the answer.
For this reason, this group has been established.

LESSONS LEARNT
company "A" does not transfer cost estimate from Eskom to company "B"

Mismatch between property ownership/rights and actual servitude requirements.

Mismatch between Eskom technical solutions offered and developer documents
point of utility coupling - gaps identified

developers risk project if scope not clearly defined and agreed with Eskom mismatch between developer EIA own solutions vs Eskom practical solution - eg cannot just rebuild new line on existing servitude while supplying customers.

Clear indication of self built with time lines/lead times to be well defined.

Q&A:
1. EIA time lapse - Can use of cables make it easier? - A: If the EIA needs to improve route - then it won't make it easier.

2. Someone from the floor said that NERSA has condoned roof top - unqualified access to grid for anything below 100kw. A:Rian says that nothing has been approved. If NERSA condones then it is something still to be developed, perhaps next year.

Another response to question 2 above: Someone added that we are talking about net metering and that local authorities are working together to try and achieve this. There is no problem with it, but we just haven't worked out the regulatory environment for it. Once this is in place, Eskom has to execute it, but to get this in place will take time. NERSA does the regulating, but at the end of the day, it must be dealt with on a local authority level. To get anything through, it will have to be sent through National Treasury. Local authorities make their revenue from electricity sales and Treasury may be weary of implementing systems which may lead to having to bail out local authorities that go bust.

3. Developers are not allowed to combine (resources?). DOE issue.

4. How to handle intermittent load of RE. Example of how Germany and Netherlands have good integrated networks and why gas can play a role as it does there, in allowing for quick response. Ramp rate of solar might also help. Noted that it is said that ramp rate in Britain is not a big issue. Example of sports event or royal wedding intermission times when there is major consumption peak (use of kettles, etc) and how the grid handled it. It is a matter of conventional and reserves being properly managed. Problem in SA is that we don't have reserve to allow for this.

Renewables sector makes local content pledge as SA unveils new green deal

South Africa's emerging renewable-energy industry committed to a minimum local content level of 35% for the initial roll-out of renewables projects, but indicated that steps would be taken to raise that level towards government's aspirational target of 75% over time.

The commitment was made in a new 'Green Economy Accord', which was signed by government, business, labour and organised community groups at a ceremony held in Cape Town on Thursday.

Vac-from-the-Sea (Plastic Recycling, green art and raising awareness about ocean pollution)

On International Coastal Clean-Up Day, plastic was collected at Hout Bay Harbour by 50 divers. The plastic debris collected was then handed over to local artist and eco-warrior, Simon Max Bannister, to construct South Africa’s first Vac from the Sea artwork in a Woodstock studio in Cape Town. By melting the plastic and using a heated spray gun Simon applies different coloured plastics onto a re-cycled vacuum cleaner to highlight our unique coastal Cape Town position where the hot and cold currents of the Atlantic and Indian oceans meet. The underlying purpose being to raise awareness about the necessity of plastic recycling and to empower people to take responsibility for ensuring a cleaner ocean and beaches.

Greenpeace Confronts Eskom - End coal addiction and embrace renewables today

07 November 2011 -

"Greenpeace activists today dropped a banner from a crane inside the construction grounds of ESKOM’s latest colossal coal-fired power plant, Kusile - reading ‘Kusile: climate killer’. At the same time, other activists have locked themselves to gates at the plant’s front entrance - protesting with banners saying ‘green jobs now’ and ‘no future in coal’ – calling on ESKOM, the utility company, to stop its coal addiction and instead invest in renewable energy projects in South Africa."

Solardome closes production facility after 42 years

"Solardome, the oldest solar water heater (swh) manufacturer in the Western Cape, will be closing its production facility at the end of November 2011.
This family owned business, founded in 1969 by Gustaf Lindenberg and run by his son, Tertius, has been producing high quality durable swh systems for 42 years. Solardome has been a landmark in the swh industry, advancing research into innovative technology, product development and most importantly creating valuable jobs in this sector.
Tertius lays the blame for the closing of their production facility at the door of the regulatory environment in this country.
At least three more swh manufacturers in the Western Cape are at the point of making the same decision as Solardome.
Since the implementation of the Eskom swh incentive programme in 2008, the industry has been through incredible flux. This programme has brought with it new regulatory costs and often unclear policy or programme changes that caused knee jerk reactions to the market. Had the programme managed to stimulate the demand for swh’s this higher regulatory cost might have been absorbed. After three years of the programme, the installation of high pressure swh’s has grown from about 16,000 to about 30,000 units per year. Even though this is a reasonable percentage growth, we are working from such a low base that it cannot be considered significant. Furthermore, if compared to the more than 500 000 standard geysers installed every year in South Africa, it is clear that the market is still operating at well below its potential. What is even more significant is that the number of suppliers of swh’s has in the same time grown from 45 to more than 500. This programme has managed to convince new businesses (mostly importers) to enter the market, but has failed to stimulate the demand in the same way.
Prior to the implementation of the swh programme approximately 50% to 70% of swh’s installed in South Africa was locally manufactured. At the outset concern was raised by several local swh manufacturers about the future viability of the industry. As part of the terms of reference of the programme, there was a commitment to implement a local manufacturing component to the calculation of the subsidy value within one year from the launch of the programme. This local content multiplier was to be implemented no later than 2009. This local content multiplier was however only announced in June 2011, but was later cancelled. It was announced that a revised structure would be implemented in October 2011. In September 2011 the implementation of the multiplier was postponed to January 2012.
On the eve of our country hosting COP17 and with the supposed promotion of renewable energy, reduction of carbon emissions and especially local economic development, it is a tragedy that a swh manufacturing business that has been in operation for more than 40 years has to close its doors.
It is probably too late for Solardome, but something has to change so that we don’t look back in a year’s time and see that every last one of our factories have closed and the only swh’s on the market are imports."

Life Cycle Cost of Coal Power

"A new Harvard University study examines the life cycle cost of coal power including all the resulting environmental and health expenses and found that although the coal itself might be cheap, the price of generating power from it is not. The study found that coal power actually costs the U.S. somewhere between $345 billion and $500 billion each year.

The study says that if all of those expenses were included in people's electricity bills, it would double to triple the cost of coal power, adding $0.09 - $0.27 per kWh, making it no longer the cheapest source of electricity, but one of the most expensive.

Some of the hidden expenses outlined in the study are elevated rates of cancer and other diseases in coal-mining regions, environmental damage to those areas (including water and air pollution), loss of tourism dollars and costs related to climate change.

The full study titled "Full cost accounting for the life cycle of coal" will be published in the Annals of the New York Academy of Sciences soon.
