the network can currently accommodate widespread micro-generation penetration at levels up to 3kWp (rural) and 4kWp (urban).

idc wrote: » Been trying to figure out the 30% export limit and reading both docs it looks like they have worked out a form of average yearly usage for annual power demand (kWh) and also one for heat demand in kWh. They have this for all the different sector use cases. For domestic it is 5220 kWh. 30% of this is 1566. So I'd expect this is how cap would work. Meaning all domestic users can export and be paid for max of 1566kWh before cap is applied.

Makes zero sense to me. Maybe I've missed something. ** You may have his the voltage threshold per string meaning you'd need another inverter

Based on the assessment report, the recommended policy option is an option that includes a Clean Export Guarantee(CEG). The advantages of a Clean Export Guarantee is that it can be provided at near cost-neutrality as the rates are provided by suppliers based on wholesale electricity prices, which also aligns with the European objectives of the recast Renewable Energy Directive. Moreover, a CEG is inherently able to provide incentives for self-consumption, energy efficiency and avoids the risk of overcompensation, which are all objectives set under the Climate Action Plan. The long-term objective is to have an arrangement that provides a market-based payment that incentivises export of electricity when the peak system demand occurs through optimising demand side time-of-use of appliances, so as to reduce the costs of supporting non-renewable back-up generation. Suppliers would then be able to offer time-of use tariffs that vary for different periods of the day and this would optimise micro-generation for system demand. This requires a system of time-of use tariffs and a deployment of Smart Meters that is not available in the Irish electricity market today but should be planned for over the lifetime of the MSS. In the interim,the CEG can be supported through an interim settlement arrangement based on a manual process, and therefore a minimum tariff is being proposed that reflects the average wholesale Day Ahead Market Price (DAM). As the CEG will not be able to meet the viability gap for the lowest cost technologies in any sector until technology costs reduce further, it is recommended that the CEG is supplemented by a Clean Export Premium(CEP) in the first years to support deployment of new renewable micro-generation. In line with the CEG, a minimum tariff by sector based on the viability gap of the lowest cost technology is being proposed. As the CEP is defined as bridging the difference between the viability gap and the CEG provided for new installations, and the technology costs are expected to reduce, there is also a planned phase-out of this subsidy over time, thereby reducing the risk of policy uncertainty or overcompensation.
CEG = SEG: A Smart Export Guarantee (SEG), which is an obligation on licensed electricity suppliers of a specific size to offer an export tariff to renewable generators with eligible installations. The suppliers can decide the level of the export tariff as well as its type and length. This could mean there could be a variety of different SEG tariffs available and generators may consider switching to suppliers with the most favourable SEG CEP = FIP: Under a feed-in premium (FIP)scheme, generators receive a premium on top of the market price of their electricity production. Premiums can either be fixed (at a constant level independent of market prices) or sliding (with levels varying in line with wholesale electricity prices). Fixed FIP schemes are simpler in design but there is a risk of overcompensation in the case of high market prices or under-compensation when market prices are low. In the case of slidingFIP schemes, the regulator faces some risk in case electricity prices decrease, as support levels fluctuate with changes in electricity market prices. On the other hand, the regulator does not risk having to pay for overcompensation, as is the case under a fixed FIP scheme. The sliding FIP scheme does however make the scheme more complex, thereby adding additional administration costs.

idc wrote: » How do you think they will monitor generation in that case? Currently the only official meter is the one where electricity enters the premises. How will they monitor a multitude of different inverters/batteries inside each house. Realistically it would need to be monitoring of the dc cables. Monitoring electricity coming out of a combo battery/inverter is no good as you'd also need to account for people filling battery from mains. Also am sure someone on one of the other PV threads mentioned how it would be easier to cheat the system if they had a meter at the fuse board inside the house for calculating pv generation!
Given the variety of different use cases within a sector and the lack of available demand data for these use cases, it was necessary to make several assumptions to determine the demand which is detailed below. The following table summarises the annual demand assumed across each sector.
Using these annual demands, annual hourly demand profiles are determined to examine supply vs demand and generate self-consumed and exported power proportions.
