Wind and solar are wholly reliant on gas.
It does not matter how many turbines or solar panels you have on the grid when there no light or wind they generate nothing and must be 100% backed up by a combination of gas, coal and nuclear (via inter-connector). All these guys talking about batteries and pumped storage can never make-up the regular failures of gas and solar. Remember batteries don't generate power, after conversion losses they store it and are necessary on the grid to manage the unexpected fluctuations in the afore mentioned technologies while other reliable generation sources are bought on-line. Pumped storage is an economics play, relying on cheap night power generation and used to meet demand surges in the morning. Pumped storage fails technically during extreme cold spells and the economics of it become doubtful with more solar being put on the grid due to the solar "duck curve".
Electricity demand is predictable, depending on random weather events on the other hand is increasing expensive to manage.
Net Zero means we are paying for the destruction of our economy and society in pursuit of an unachievable and pointless policy.

They are telling you why they are putting in batteries, random energy is destabilising grid operations and grid management and infrastructure costs are increasing as a direct consequence. Do you know what is involved with solar on the grid? at night you need reliable power sources that must be rapidly spun down as the sun rises, then when the sun sets they must be spun up rapidly again - that is expensive and a complex operation because the both wind and solar are diffuse and intermittent.
Greencoat commissions Fluence battery storage system for Irish wind farm
The proprietary Gridstack product is designed for frequency regulation, flexible peaking capacity and enhanced transmission and distribution services. It also includes intelligent controls and an edge-to-cloud communication platform for faster frequency response.
RWE’s largest battery storage project goes live in Monaghan, Ireland
Deployment of battery storage like Lisdrumdoagh, will be capable of a rapid response to frequency changes, importing or exporting electricity from the grid as needed, and helping efficiently stabilise the grid, while guaranteeing reliable electricity supply for users.
Ireland's First Synchronous Condenser System to Stabilize Irish Grid
The synchronous condenser, a key component of the ESB's Green Atlantic @ Moneypoint project, will be the first in the country and incorporate the world's largest flywheel used for grid stability. The facility will enable an increased integration of wind power into the Irish grid by providing sufficient inertia for frequency support, short-circuit power for system strength, and reactive power for voltage control. Commissioning of the new plant is planned for mid-2022.
EirGrid, Electricity and Turf (Amendment) Bill 2022: Second Stage
However, the most immediate factor affecting security of electricity supply in Ireland over the coming years is a potential generation capacity shortfall that was identified in EirGrid's all-island generation capacity statement published in September 2021. This potential capacity shortfall arises in periods of peak demand when there are low levels of wind generation and interconnection available to the system. The shortfall has arisen largely due to non-delivery of previously contracted capacity, increasing electricity demand and the increasing unreliability of existing plant.
What is happening in Ireland is happening across Western Europe (Critically nuclear in France because they export power to their neigbours) and to an extent the USA, but also Canada and Australia. The old plants have come to the end of their design life and they are are being run down with no new investment. They are NOT designed to work efficiently with intermittent, diffuse and costly generation schemes. To try and counteract that the CRU in Ireland has to pay gas plants to provide standby capacity. Every one of those turbines have to be replaced after 20 years, do our think they can put in bigger turbines on site? The existing concrete and steel foundations are not designed for that. There is the nuts idea to put turbines out to sea on the Atlantic, the lifespan of turbines at sea is probably around 12 years if that, the maintenance costs of equipment at sea rise rapidly. None of this is cheap.
Net Zero means we are paying for the destruction of our economy and society in pursuit of an unachievable and pointless policy.
